WiFi and WiFi/BLE-to-USB Adapter

The USB adapter enables the wireless connectivity of the Logger:

• Connection to the Fluke Connect™ smartphone app for easy asset management and data sharing.
  • Data transfer to Energy Analyze Plus PC software.
• Display and store data of up to 2 modules of the Fluke FC 3000 series together with the instrument data into logging sessions (requires WiFi/BLE or Bluetooth adapter feature, available with firmware version 2.0).
  • Stream all data to the Fluke Connect Cloud
• Manage assets and share data with the Fluke Connect smartphone app.

To install adapter sin the Logger:

1. Remove the three screws in the battery door. See Figure 1.
2. Remove the battery door.
3. Remove the battery.
4. Insert one or two WiFi/BLE adapters into the battery compartment with the serial number facing towards the front of the Logger and gently push until the adapter snaps into the USB socket. About 3.5 mm (0.14 in) of the metal shield should be visible.
5. Connect the USB Bluetooth adapter on either the internal or external USB port.

Figure 1. Adapter Installation

Magnet Hanger Kit

Use the Magnet Hanger Kit to hang the Product. See Figure 2.

Figure 2. Magnet Hanger Kit
Caution
Always use two magnets to hang the Product.

Voltage Test Leads

Voltage test leads are four-core, flat, test leads that do not tangle and can be installed in tight spaces. On installations where the access to Neutral is out of reach with the three-phase test lead, use the black test lead to extend the Neutral lead.

For single phase measurements use the red and black test leads.

iFlexi Current Probe

The iFlexi Current Probe works on the Rogowski coil (R-coil) principle that is a toroid of wire used to measure an alternating current through a wire encircled by the toroid. See Figure 3.

Figure 3. R-Coil Operation Principle

The R-coil has advantages over other types of current transformers:

• It is not a closed loop. The second terminal is passed back through the center of the toroid core (commonly a plastic or rubber tube) and connected along the first terminal. This allows the coil to be open-ended, flexible, and able to be wrapped around a live conductor without disturbing it.
• It has an air core rather than an iron core. It has a low inductance and can respond to fast-changing currents.
• Because it has no iron core to saturate, it is highly linear even when subjected to large currents, such as those used in electric power transmission or pulsed-power applications.

1742/1746/1748

Users Manual

A correctly formed R-coil, with equally spaced windings, is largely immune to electromagnetic interference.

Use the cable markers for easy identification of the four current probes. Apply the markers on both ends of the current probe cable. See Figure 4.

Figure 4. Test Leads with Color Coding

Storage

When not in use, keep the Logger in the protective storage bag/case. The bag/case has sufficient space for the Logger and all the accessories.

If the Logger is stored for an extended period of time or is not in use for a long time, you should charge the battery at least once every six months.

• Windows 7 32/64-bit, Windows 8 32/64-bit.

Note

Windows 7 Starter edition and Windows 8 RT are not supported. Energy Analyze Plus also works on Windows XP systems, but is not specifically tested because XP support is discontinued.

How to Connect to Energy Analyze Plus

The Logger supports several interfaces to connect to the PC:

• USB cable
• Ethernet
  • WiFi - direct connection
  • WiFi - connection to infrastructure

Note

WiFi connectivity requires that a radio certification for the WiFi or WiFi/BLE adapter is available for your country. Check www.fluke.com for availability.

After one or more connections are established, Energy Analyze Plus software shows the Logger in the list of found devices. Choose the Logger to setup and/or download measurement data from.

USB Cable

To connect the PC to the Logger:

1. Turn on the computer and the Logger.

2. Make sure Energy Analyze Plus Software is installed. The software installation also installs the required drivers.

3. Connect the USB cable to the USB ports of the computer and the Logger. See Figure 9.

Figure 9. Power Logger to PC Connections

1. The USB cable connection uses a network communication over USB (Remote NDIS network) with Internet Protocol IPv6. When you connect the Logger with the RNDIS network interface, a serial port "USB Serial Port (COMx)" appears in Windows device manager. This serial port is for production and service/calibration purposes only.

Note

Make sure IPv6 is enabled on your Windows system.

Ethernet

Use a commercially available Cat 5 or higher Ethernet patch cable to connect the Logger to your LAN (local area network). A communication over Ethernet requires that each device has a unique IP address. Two options exist: Either a device obtains an address from a DHCP server or the device uses a static, user-configured address.

The default setting of the Logger is to obtain an IP address from a DHCP server automatically. The Ethernet LED (4) flashes when a link has been established but no IP address is assigned. Once the Logger IP address is assigned, the LED is steady green. Navigate to the Network Configuration of the remote control client to identify the assigned IP address, subnet mask and gateway.

Optionally, you can configure a static IP address, subnet mask, and gateway. Be sure that the LAN supports static address assignment. A connection to the device is only possible if the IP address range of the computer matches with the IP address of the Logger. The range is specified with the subnet mask. For example, a Logger with an IP address 192.168.0.100 and a subnet mask of 255.255.255.0 is accessed by a PC only when its IP address is any address between 192.168.0.1 and 192.168.0.254 except the Logger address.

The Logger allows a Ethernet point-to-point connection between the Logger and a PC. The Logger has Auto-MDI-X support to switch automatically between 1:1 for a device-to-LAN connection and cross-over mode required for a device-to-device connection. A cross-over cable is not required. The Logger and PC self-assign IP addresses in the range of 169.254.x.x automatically after the timeout to receive an IP address from a DHCP server expires.

Note

During the typical timeout of 1 minute, Windows shows the status "Identifying" in the network status. Windows may show an exclamation mark in the network status icon indicating that the connection does not provide Internet access. This is normal.

The Logger communicates with the Fluke Energy Analyze Plus software on following ports:

Type Port Number

TCP 80 (HTTP)

TCP 443 (HTTPS)

TCP 18571

UDP 123 (NTP)

UDP 18571

The software installer for Energy Analyze Plus automatically adds exceptions to the Windows firewall. If a third party firewall is used, add the ports and the application fea.exe to the exception list.

WiFi Direct Connect

With the built in USB WiFi Adapter you can wirelessly control the Logger and download measurement data to the Energy Analyze Plus software. The WiFi direct connection uses WPA2-PSK (pre-shared key) with AES encryption.

To make a WiFi connection:

1. If not already, enable the WiFi Hotspot on the Logger.

A green WiFi Hotspot LED indicates that the connection is active. If the LED is off, the WiFi/BLE-to-USB is not installed. See WiFi and WiFi/BLE-to-USB Adapter.

1. On the client, go to the list of available WiFi networks and look for a network with the name: "Fluke174x" for example: "Fluke1746<12345678>.

2. At the prompt for WiFi passphrase, enter fluketools.

Depending on the operating system of the client, the passphrase is also called Security Key, Password, or similar. After a few seconds, the connection is established.

A blue WiFi Hotspot LED indicates an established connection with a client.

Note

Windows checks if the WiFi connection enables an Internet connection. This may take up to one minute until the Logger is accessible. A missing Internet connection is indicated by "No Internet" in Windows 10 or with an exclamation mark in the WiFi icon on Windows 7. This is normal since the Logger is not a gateway to the Internet.

WiFi to Infrastructure

With a second WiFi-to-USB adapter the Logger can connect to a WiFi access point. No security and WPA2-PSK security is supported. This connection requires a DHCP service running in the access point to assign IP addresses automatically.

Note

This feature requires the WiFi-Infrastructure license.

To connect to an access point:

1. Select the access point from the list of found SSID (Service Set Identifier - name of the access point) or enter the name of a hidden SSID.

2. Enter the passphrase (8 to 63 characters) of the access point.

A blinking green WiFi LED (8) shows while the Logger tries to establish a connection to the configured access point. This takes usually a few seconds. A solid green LED indicates the connection is ready. Consult the remote control tool for a field strength indication of the access point. If the WiFi symbol shows only one to two green bars, the WiFi connection might be unreliably. Reasons for a permanently blinking LED or blinking after the LED was solid green already:

• No access point configured.
• The configured access point is out of reach.
• The password is incorrect.

In all cases, see the remote control tool for more details.

- Load Study: For convenience, some applications require you to measure only the current that makes the connection to the point to measure.

Typical applications are:

• Verify the circuit capacity before adding additional load.
• Identify situations where the allowable load can be exceeded.

Optionally, a nominal voltage can be configured to get pseudo-apparent power readings.

Load Study (no voltage measurement)

Nominal Voltage

Select a nominal voltage from the list. If a voltage is not shown in the list, enter a custom voltage. On energy studies, the nominal voltage is required to determine the limits for dips, swells, and interruptions.

The nominal voltage on load studies is used to calculate the pseudo apparent power:

nominal voltage x measured current

Nominal Frequency

Set the nominal frequency to be the same as the power line frequency, 50 Hz or 60 Hz.

Voltage Ratio (only in energy studies)

Configure a ratio factor for the voltage inputs when a potential transformer (PT) is in series with the voltage connections such as when you want to monitor a medium-voltage network. The default value is 1:1.

Current Range

Configure the current range of the attached sensor:

• Auto
  When set to Auto, the current range is set automatically and depends on the measured current.
• Low Range
  Low Range is 1/10 of the nominal range of the attached current sensor. For example, the low range of an iFlex1500-12 is 150 A.

- High Range

High Range is the nominal range of the attached current sensor. For example, 1500 A is the nominal range on an iFlex1500-12.

Note

Set the current range to Auto when you are not sure about the maximum current during the logging session. A specific application can require you to set the current range to a fixed range rather than Auto. This can occur because the Auto range is not gapless and may lose too much information in the case of a highly fluctuating current.

Current Ratio

Configure a ratio factor for the current sensors when a current transducer (CT) is used to measure the much higher level on the primary side at a substation or step-down transformer that has a built-in metering current transformer.

Use the current ratio to increase the sensitivity of the iFlex sensor. Wrap the iFlex sensor around the primary conductor, for example 2X, and enter a ratio factor of 0.5:1 to get correct readings. The default value is 1:1.

Harmonics Calculation Method

Select the harmonic calculation method to apply according to IEC 61000-4-7. The Logger applies a FFT (Fast Fourier Transformation) every 10/12 cycles (typical 200 ms), that delivers spectral components (bins) every 5 Hz from dc up to 12 fs. fs is the sample frequency of the A/D converter, for example, 10.24 kHz. The standard allows three different ways to calculate the harmonics from these 5 Hz components: Harmonic Components, Harmonic Sub-Groups, and Harmonic Groups.

Overview.

	Harmonics Interharmonics
Harmonic Components(required for measurements according to certain standards, such as IEEE519 or IEC 61000-3-12)	RMS value of a single 5 Hz component	RMS value of all bins between two harmonics
Sub-Grouped Harmonics (default)(for IEC 61000-4-30 compliant measurements, such as EN50160)	RMS value of the harmonic frequency and adjacent bins	RMS value of all bins between two harmonics
Grouped Harmonics	RMS value of the harmonic frequency and 12 of the interharmonic spectrum to both sides	not available

Harmonic Components. The fundamental h01 and harmonics h02 ... h50 are represented by the bin of the harmonic frequency.

The interharmonics ih01 ... ih50 are calculated from all spectral components between two consecutive harmonic frequencies.

Examples:

• On a 60 Hz system, the h02 at 120 Hz is represented by the bin no. 24 (120 Hz / 5 Hz = 24).
• The harmonic h03 at 180Hz is represented by the bin no. 36 (180 Hz / 5 Hz = 36).
• The interharmonic ih02 is represented by the bins no. 25 – 35 (125 Hz ... 175 Hz).

Select Harmonic Components for measurements according to standards that require the harmonics components measurement according to IEC 61000-4-7 or IEC 61000-3-12.

Sub-Grouped Harmonics. The fundamental h01 and harmonics h02 ... h50 are the RMS average of the bin of the harmonic frequency and one adjacent bin to each side.

The interharmonics ih01 ... ih50 are composed of the remaining seven bins for 50Hz systems or nine bins for 60Hz systems between two adjacent harmonics.

Examples:

• Select Harmonic Components for measurements according to standards that require the harmonics components measurement according to IEC 61000-4-7, for example IEEE 519 or IEC 61000-3-12.
• The harmonic h03 at 180 Hz is represented by the bin no. 35, 36, and 37 (180 Hz / 5 Hz = 36).
• The interharmonic ih02 is represented by the bins no. 26 – 34 (130 Hz ... 175 Hz).

Note

Many power quality standards, such as EN 50160 and GOST 33073, refer to IEC 61000-4-30 Class A measurement methods that require Harmonic Sub-Groups.

Grouped Harmonics.

The fundamental h01 and harmonics h02 ... h50 are the RMS average of the bin of the harmonic frequency and half of the bins between two adjacent harmonic frequencies to both sides. The center bin between two harmonic frequencies is included in both harmonics with 50 %. Bins between h01 and h02 are not included.

Interharmonics are not available when the selection is grouped harmonics.

Examples:

• On a 60 Hz system, the harmonic h03 at 180 Hz is represented by the bins 31-35, 36, 37-41, 50 % of bin no. 30 and 50 % of bin no. 42
• The harmonic h04 at 240 Hz is represented by the bin no. 43-47, 48, 49-53, 50 % of bin no. 42 and 50 % of bin no. 54

The advantage of the measurements using grouped harmonics is to cover the entire spectrum without the need to store memory-consuming interharmonics. Make sure to apply this measurement only if the applicable standard requires this measurement method.

Flicker

The Logger supports the assessment of Flicker severity according to IEC 61000-4-15.

Select the lamp-model voltage applied within the Flicker measurement algorithm. Make sure the lamp model selection matches the Nominal Voltage setting unless the measurement includes the use of voltage transducers. In this case make sure to select a lamp-model voltage that matches the Nominal Voltage definition of the associated low voltage grid.

Configuration of Events

Voltage Dips

On single-phase systems, a voltage dip begins when the voltage falls below the dip threshold, and ends when the voltage is equal to or above the dip threshold plus the hysteresis voltage. See Figure 10.

Figure 10. Characteristics of a Voltage Dip

On polyphase systems, a dip begins when the voltage of one or more channels is below the dip threshold and ends when the voltage on all measured channels is equal to or above the dip threshold plus the hysteresis voltage.

Choose nominal or sliding reference voltage. A sliding reference voltage uses measured values filtered with a 1-minute time constant and applies usually only for medium and high voltage systems.

Parameters to configure:

• Limit
  The threshold limit value is defined as % of nominal voltage or sliding reference. The default value is 90 % and the hysteresis is 2 %.

Voltage Swells

On single-phase systems, a swell begins when the voltage rises above the swell threshold, and ends when the voltage is equal to or below the swell threshold minus the hysteresis voltage. See Figure 11.

Figure 11. Characteristics of a Voltage Swell

On polyphase systems, a swell begins when the voltage of one or more channels is above the swell threshold and ends when the voltage on all measured channels is equal to or below the swell threshold minus the hysteresis voltage.

Choose nominal or sliding reference voltage. A sliding reference voltage uses measured values filtered with a 1-minute time constant and applies usually only for medium and high voltage systems.

Parameters to configure:

- Limit

The threshold limit value is defined as % of nominal voltage or sliding reference. The default value is 110 % and the hysteresis is 2 %.

Voltage Interruptions

On single-phase systems, a voltage interruption begins when the voltage falls below the voltage interruption threshold and ends when the value is equal to or greater than the voltage interruption threshold plus the hysteresis. See Figure 12.

Figure 12. Characteristics of a Voltage Interruption

On polyphase systems, a voltage interruption begins when the voltages of all channels fall below the voltage interruption threshold and ends when the voltage on any one channel is equal to, or greater than, the voltage interruption threshold plus the hysteresis.

Note

On polyphase systems, the event is still classified as a dip when the voltage of only one or two phases falls below the interruption limit.

Parameters to configure:

- Limit

The threshold limit value is defined as % of nominal voltage. The default value is 5 % and the hysteresis is 2 %.

Rapid Voltage Changes

Rapid voltage changes (RVC) are quick transitions of the RMS voltage between two steady states. Rapid voltage changes are captured based on RVC threshold. RVC threshold are set as percentage of the nominal voltage and the threshold level is calculated over the preceding 100/120 U_rms(1/2) values. (100/120 is defined as 100 values for 50 Hz nominal or 120 values for 60 Hz nominal.) An RVC Event is detected when the arithmetic mean of 100/120 U_rms(1/2) values falls outside the an RVC threshold. When a voltage change crosses the dip or swell thresholds, it is considered a dip or swell and not a rapid voltage change. The event list shows the voltage step, transition time, and Vmax. See Figure 13.

Parameters to configure:

• Trigger on/off
• Limit

The voltage Threshold limit value is defined as % of nominal voltage. The values is typically in the range of 1 % to 6 %. The RVC hysteresis shall be less than the RVC threshold and is typically 50 % of the RVC.

Waveform Deviation

The Waveform Deviation trigger monitors the differences in the waveforms of consecutive voltage cycles. Each sample magnitude of the last cycle is compared with the sample magnitude of the actual cycle. The trigger starts when the difference exceeds the configured limit and ends when the difference is lower than the threshold minus the hysteresis. If a waveform deviation triggers starts within one second after the previous waveform deviation trigger ended, it is combined to one event.

Figure 13. Rapid Voltage Change Characteristics

This trigger is a general-purpose trigger that detects non-stationary phenomena and is perfectly suitable for all kinds of disturbance analysis and troubleshooting, because most of the power quality problems result in a sudden change of the waveform. From the recorded waveforms, in most cases the root-cause of distortions can be identified: Switching of capacitor banks, commutation distortions, and oscillations on the mains supply. In addition, ground shorts in the medium voltage systems with their typical significant waveforms can be identified. See Figure 14.

Figure 14. Waveform Deviation

Parameters to configure:

• Trigger on/off
• Limit

The voltage threshold limit is the maximum deviation of the sample magnitude of the actual cycle to the magnitude of the previous cycle in % of nominal voltage.

Recommendation of values depending on the required trigger sensitivity:

Power distribution systems can carry control signals to remotely switch on and off appliances (also known as ripple control). The control signals are present only at the moments that a remote appliance has to be controlled. The Mains Signaling trigger can capture the occurrence (signal level) of control signals with 2 different frequencies.

Parameters to configure:

• Trigger on/off
• Mains Signaling Voltage (MSV) frequency 1 and MSV frequency 2 in Hz
  • Frequency range is 100 Hz up to 3000 Hz
• Limit

The voltage threshold limit value is defined as % of nominal voltage. The value is typically in the range of 1 % to 5 %.

- Recording time

The event triggers a 10/12 cycle recording of up to 120s.

Inrush Current

Inrush currents are surge currents that occur when a large or low-impedance load comes on line. Normally the current will stabilize after some time when the load has reached normal working condition. For example, the start-up current in induction motors can be 10x the normal working current. See Figure 15. The inrush current begins when the 1/2-cycle RMS current rises above the inrush threshold, and ends when the 1/2-cycle RMS current is equal to or below the inrush threshold minus the hysteresis value. In the event table, the extreme value is the highest 1/2-cycle RMS value of the event.

Figure 15. Inrush Characteristics

Parameters to configure:

• Trigger on/off
• Limit
  The current threshold limit is the 12 cycle RMS value in A. A signal exceeding this limit triggers the event.

Logging Session Setup

Name. The Logger auto-generates a file name with the format ES.xxx or LS.xxx. ES ... Energy Study LS ... Load Study xxx ... incremental file number The counter resets when the Logger is set to factory defaults. See Reset to Factory Defaults for details. You can also choose a custom file name with up to 31 characters.

Description. Enter more details about the measurement, such as customer, location, and load-rating plate data. This description field is limited to 127 characters. After you download a logging session with Energy Analyze software, the description can be also entered or modified.

Trend Interval. Select the time interval when a new average value is added to the logging session. The available intervals are: 1 s, 5 s, 10 s, 30 s, 1 min, 5 min, 10 min, 15 min, 30 min. A shorter interval provides more details at the cost of higher memory consumption.

Examples of when a short interval is useful:

• Identify duty cycle of frequently switching loads
• Energy cost calculation of production steps

Demand Interval. Electrical suppliers use this interval to measure the customer demand. Select an interval to get energy costs and the maximum demand value (average power measured over a demand interval). A value of 15 minutes is normal. If the average interval is unknown, select 5 minutes. You can recalculate other interval lengths offline using the Energy Analyze Plus software.

Note

This value is not available for load studies.

Duration and Recording Start/Stop Date and Time. The start and stop of a logging session can be defined as:

- Start/Stop button

Start/stop the logging session manually with the Start/Stop button on the Logger. The Logger takes the pre-configured settings and records data until the configured duration has elapsed or the Start/Stop button on the Logger is pressed.

- Immediate start

When this option is selected the Logger starts the logging session immediately. The end of the logging session is configured by the duration or by a stop date and time. The logging session can always be stopped with the remote client or pushing the Start/Stop button on the Logger for >3s.

Note

The 3 s (150/180 cycles) and 10 min interval used for power quality graphs, harmonics, and PQ standard assessment according to EN50160 and IEEE519 is synchronized to the clock and starts and stops always at 10 min boundaries. For example, a logging session from 09:05 to 09:35 contains two 10 minute intervals: One interval from 09:10 to 09:20 and one interval from 09:20 to 09:30.

- Configure a scheduled recording

Configure a scheduled recording by the duration and the start date and time or by the start date and time and stop date and time. This is a convenient method for how to set up the Logger to measure a full week profile starting on Monday 0:00 and ending on Sunday 24:00. You can set the duration of the measurement from a list. Maximum configures the maximum possible duration based on the available memory. For a duration not shown in the list, select Custom to enter the duration in number of hours or days. The logging session stops automatically when the time duration has elapsed. You can manually stop the logging session at any time.

Note

Even when a start date and time has been configured, you must push the Start/Stop button on the Logger.

Connection Verification and Correction

Once the measurement is configured and the voltage and current inputs are connected to the system under test, use the Connection Verification window to confirm the connection.

The verification detects:

• Too low signal
  • Phase rotation for voltage and current
  • Inverted current probes
• Wrong phase map

In the connection verification window:

1. Toggle Current Flow between Generator Mode and Motor Mode.

Usually the current flow direction is toward the load. Use Motor Mode for these applications. Use the Generator Mode when the current sensors are connected intentionally to the generator (for example, during the time energy goes into the grid from regenerative braking system of an elevator or on-site wind turbines).

The current flow arrow indicates the correct flow: a normal condition is shown in Load Mode with a black arrow pointing upwards, in Generator Mode the black arrow points downwards. If the arrow is shown in red, the current flow direction is inverted.

1. Digitally swap phases and invert the current inputs instead of a manual correction:

2. Click on the voltage or current input 1, 2, or 3 to select a phase.

3. Select another input.

4. If the Logger is able to determine a better phase map or polarity, click on Auto Correct to apply the new settings.

Auto Correct is not available if the algorithm is not able to detect a better phase map or when no errors are detected.

Note

It is impossible to detect all incorrect hook-ups automatically. You must verify the suggested modifications carefully before you apply the digital correction. Applications with single-phase energy generation can deliver the wrong results when you apply the Auto Correct feature.

The algorithm creates a sequence with a clockwise phase rotation.

Instrument Setup

This setup section is about the requirements to perform a power or power quality study. The setup will verify that the details of the study are correct and that useful, actionable data is collected for reports.

Instrument Name

You can assign a name to the Logger. This name is attached to the measurement files when you review these files in Energy Analyze Plus software. The default name is FLUKE174x, for example: FLUKE1748<12345678>.

User credentials. This allows to configure custom user credentials to permit access to the device configuration. The factory defaults are:

User name: admin

Password: admin

If you do not know the credentials, download recorded data from the Logger and perform a factory reset with the Start/Stop button during power-on. See Reset to Factory Defaults for more information.

Time Synchronization

Set one of the available clock sources:

Manual. Manually synchronize the Logger clock with the clock of the remote client. In Energy Analyze, it is also called "PC Time".

The clock meets the requirements defined in IEC 61000-4-30 Class A to allow a maximum deviation of 1 s/day when the synchronization is unavailable.

Internet Time. The Logger will contact a time server on the Internet (NTP) and keeps the real-time clock synchronized during long logging sessions. This setting requires a connection to the Internet. See Network configuration for details. Time stamps of resulting logging data will be more accurate than using the manual time synchronization mode also over longer periods, but may not comply with IEC 61000-4-30 Class A requirements.

GPS. Set this option when using the GPS receiver FLUKE-174X GPS-REC. Refer also to GPS Time Synchronization Input for details. For IEC 61000-4-30 Class A measurements Fluke recommends that you use this setting for the best real time accuracy of less than ±1 cycle.

Ethernet Configuration

Use the Ethernet port to configure the Logger and download measurement data with Energy Analyze Plus software. The Ethernet port is also used for the Network Time Protocol (NTP) to periodically synchronize the real-time clock when Internet Time is configured. You can either enter a specific address or indicate that the address is found automatically over the network.

Note

An automatic address is assigned by a DHCP server if one is available on the network. Otherwise, contact the networking or IT department to get access to fixed IP address.

Update Firmware

Note

A firmware update deletes all measurement data.

To update:

1. On a USB drive with at least 80 MB of free space available, create a folder named Fluke174x (no spaces in file name).

Note

Make sure the USB drive is formatted with FAT or FAT32 file system. In Windows, USB drives ≥ 32GB can be formatted with FAT/FAT32 only by using 3rd party tools.

1. Copy the firmware file (*.bin) into this folder. If more than one firmware file (*.bin) is located in the Fluke174x folder, the newest version is used for the update.
2. Make sure the Logger is powered from mains and a connection to Energy Analyze Plus established.
3. Plug the USB drive into the Logger.
4. Select Firmware update from Instrument Settings and follow the instructions.

The firmware update takes approximately 5 minutes. During this time, the Start/Stop LED is blinking white. When the firmware update is complete, the Logger restarts automatically. A solid green or amber Start/Stop LED indicates the Logger is in the restart process.

License Activation

To activate a license from a PC:

1. Go to www.fluke.com.
2. Go to the product registration page and select your region, country, and language.
3. Select Brand > Fluke Industrial.
4. Select Product Family > Power Quality Tools.

5. Select Model Name > Fluke 1742, Fluke 1746 or Fluke 1748.

6. Enter the serial number of the Logger.

Note

You must enter the serial number correctly (no blank characters allowed). The serial number is an 8-digit number and is found in the Logger Setup or on the back decal of the Logger.

1. Enter the license key from the license activation letter. The web form supports up to two license keys. You can enable licensed features at a later time by returning to the web registration page.

Note

The activation of the WiFi Infrastructure does not require a license key.

1. Complete all the fields and submit the form. An e-mail with the license file is sent to your e-mail address.
2. Create a folder named "Fluke174x" on a USB drive. Do not use spaces in the file name. Make sure the USB is formatted with FAT or FAT32 file system. (In Windows, USB drives ≥32 GB can be formatted with FAT/FAT32 only with 3rd party tools.)
3. Copy the license file (*.txt) to this folder.
4. Make sure the Logger is powered from mains and a connection to Energy Analyze Plus established.
5. Insert the USB drive into the Logger.

Select New License > Install from Instrument Settings and follow the instructions.

Retrieve Service Data from the Logger

If requested for customer support, use this function to copy all measurement files in raw format and system information:

1. On a USB drive with sufficient available memory depending on the file size of stored logging sessions (max 2GB) create a folder called Fluke174x (no spaces in file name).
2. Create a file CopyServiceData.txt in the Fluke174x folder.
3. Make sure the Logger is powered from mains.
4. Plug the USB drive into the Logger.

All relevant measurement data is copied to the USB drive. During the file transfer the Start/Stop LED flashes white. This may take a few minutes depending on the amount of stored data. You can remove the USB drive when the Start/Stop LED changes color to green. If the LED is amber, an important warning or information is available. See the remote control software, such as Energy Analyze Plus, for details.

Note

Service data is copied to the USB drive when you insert the USB drive into the Logger. Remove or change the name of the CopyServiceData.txt file to disable this feature.

Reset to Factory Defaults

To reset the Logger with Energy Analyze Plus software, click the Factory reset button. A display message prompts you to continue or cancel the reset.

Note

A reset to factory defaults from the remote client does not affect the licenses installed on the Logger.

To reset the Logger to factory defaults with the Start/Stop button during power-on:

1. Turn on the Logger with the Start/Stop button and keep the button pressed for about 5 s until all status LEDs turn red.
2. Release the Start/Stop button.

The status LEDs start to blink green.

1. Press the Start/Stop button again until the status LEDs confirm the factory reset with a solid green color.

The Logger continues the boot process.

Note

A reset to factory defaults during the power-on sequence removes all installed licenses from the Logger.

Caution

When the Start/Stop button is pressed for >8 seconds the Logger performs a soft reset. This is the last option if the Logger is no longer responsive. A soft reset during an active logging session can cause loss of data.

Auto-Copy Data to USB

The Logger supports automatic actions on insertion of the USB drive. This is helpful to gather data from the Logger without the need to establish a connection to the Logger to download the data to the PC.

To enable the auto-copy mode:

1. On a USB drive, create the folder Fluke174x (no spaces in file name).
2. Create a file AutoCopyData.txt in the Fluke174x folder.
3. Make sure the Logger is powered from mains.
4. Plug the USB drive into the Logger.

All recorded measurement data is copied to the USB disk. During the file transfer the Start/Stop LED flashes white. This may take a few minutes depending on the amount of stored data. You can remove the USB drive when the Start/Stop LED changes color to green. If the LED is amber, an important warning or information is available. See the remote control software, such as Energy Analyze Plus, for details.

Note

Measurement data is copied to the USB disk when you insert the USB drive into the Logger. Remove or change the name of the AutoCopyData.txt file to disable this feature.

GPS Time Synchronization

With the optional GPS receiver (FLUKE-174X GPS-REC), the Logger has the best possible real-time accuracy of typically 1 ms and complies to the time synchronization requirements of IEC61000-4-30 Class A.

To use GPS time synchronization:

1. In Instrument Setup configure the Time Synchronization Source to GPS.

The Time LED on the Logger turns red to indicate an invalid time synchronization status and no connection to the GPS receiver.

1. Attach the GPS receiver FLUKE-174X GPS-REC to the I/O Connector (12).

2. Position the receiver at a location with clear view to the sky.

Due to the extreme low signal strength of the satellites, consider an outdoor location for a reliable time synchronization. The acquisition takes approximately 1 minute until enough satellites are identified to use for the time synchronization.

The Time LED turns green when the GPS receiver provides reliable time synchronization.

Glossary

Unbalance (u2) Supply Voltage Unbalance

Condition in a three phase system in which the RMS values of the line-to-line voltages (fundamental component), or the phase angles between consecutive line voltages, are not all equal. The unbalance value is the ratio of the negative sequence to the positive sequence in percent and is typically in the range between 0 % and 2 %.

h01 [V, A] Fundamental Frequency Component

RMS value of the fundamental frequency component of voltage or current. Sub grouping according to IEC 61000-4-7 is applied.

h02 ... h50 [%] Harmonic component of voltage or current.

The ratio of the RMS value of the voltage or current harmonic components h02 ... h50 to the RMS value of the fundamental component h01 of voltage or current. Depending on the selected harmonics calculation method, Sub grouping, grouping or harmonic component is applied according to IEC 61000-4-7.

THD [%] Total Harmonic Distortion

The ratio of the RMS value of the sum of all the voltage or current harmonic components h02 ... h50 to the RMS value of the fundamental component h01 of voltage or current.

THC [V, A] Total Harmonic Content

The RMS value of the sum of all the voltage or current harmonic components h02 ... h50.

The ratio of the RMS value of the voltage or current interharmonic components ih01... ih50 to the RMS value of the fundamental component h01 of voltage or current. Depending on the selected harmonics calculation method, Sub grouping or harmonic component is applied according to IEC 61000-4-7.

TID [%] Total Interharmonic Distortion

The ratio of the RMS value of the sum of all voltage or current interharmonic components ih01 ... ih50 to the RMS value of the fundamental component h01 of voltage or current. Depending on the selected harmonics calculation method, Sub grouping or harmonic component is applied according to IEC 61000-4-7.

TIC [V, A] Total Interharmonic Content

The RMS value of the sum of all the voltage or current interharmonic components ih02 ... ih50.

TDD ^[1] [%] Total Demand Distortion

The ratio of the RMS value of the sum of all the current harmonic components h02 ... h50 to I_L , the maximum demand current.

I_L^[1] [A] Maximum Demand Load Current

The current value is established at the point of common coupling and should be taken as the sum of the currents corresponding to the maximum demand during each of the twelve previous months divided by 12.

This value is required to calculate TDD and to determine the applicable current harmonic limits defined by IEEE 519. This value is a user input in the measurement configuration.

I_sc^[1] [A] Maximum Short Circuit Current at Point of Common Coupling

This value is required to determine the applicable current harmonic limits defined by IEEE 519. This value is a user input in the measurement configuration.

P_ST, P_LT PST is the short term flicker value calculated over defined 10-minute periods. PLT is the long term flicker calculated over defined 2-hour periods.

Example:

Measurement at 120 V/16 A using an iFlex1500-12 in low range. Power Factor is 0.8

Active power uncertainty _P

$$ \sigma_ {P} = \pm \left(\left(1. 2 \% + \frac {\sqrt {1 - 0 . 8 ^ {2}}}{2 0 .}\right) + 0. 0 0 5 \% R _ {\text {Range}}\right) = \pm (1. 5 7 5 \% + 0. 0 0 5 \% \times 1 0 0 0 \mathrm{V} \times 1 5 0 \mathrm{A}) = \pm (1. 5 7 5 \% + 7. 5 \mathrm{W}) $$

The uncertainty in W is ±(1.575 % × 120 V × 16 A × 0.8 + 7.5 W) = ±31.7 W

Apparent power uncertainty _S

$$ \sigma_ {S} = \pm (1. 2 \% 0. 0 0 5 \% S \times \text { Range }) = \pm (1. 2 \% + 0. 0 0 5 \% \times 1 0 0 0 V \times 1 5 0 A) = \pm (1. 2 \% + 7. 5 V A) $$

The uncertainty in VA is ±(1.2 % × 120 V × 16 A + 7.5VA) = ±30.54 VA

Reactive/non-active power uncertainty _Q

$$ \sigma_ {Q} = \pm (2. 5 \% \times S) = \pm (2. 5 \% \times 1 2 0 V \times 1 6 A) = \pm 4 8 \text {var} $$

In case of a measured voltage that is >250 V, the additional error is calculated with:
