Introduction

The Fluke 1750 Power Recorder is a comprehensive yet easy to use system for power quality investigations. The 1750 Power Recorder, referred to hereafter as simply “the Recorder or the Product,” consists of a power recorder instrument, a wireless handheld Personal Digital Assistant (PDA) for control and setup, and a powerful yet easy to use PC application, Power Analyze. Four 400 A current probes are provided as standard equipment (not included in Basic version). A wide range of flexible and clamp-on current probes are available from Fluke.

Key features of the 1750 Power Recorder are:

- No PC needed for setup

Using the included wireless-enabled Personal Digital Assistant (PDA) as a controller, you do not need a PC to configure the Recorder, troubleshoot connections, preview data, or download the recorded data. Downloaded data goes onto the SD memory card plugged into the 1750, not directly to the PDA. The range of the PDA with the wireless link is about 5 meters (16 feet) from the Recorder. This range is dependent on the electrical interference in the location.

- Simplified test lead connections to the power network

Simply connect a voltage probe to a conductor on each phase that you want to record. On the current inputs, the Recorder automatically identifies what type of probe is connected. The Recorder then configures its measurement system appropriately for the model of current probe you are using.

- Connection diagrams for the supported power network configurations (delta, Wye, and others) appear on the handheld PDA controller. Once you make connections, you can view live readings and a phasor diagram on the PDA to confirm the connections. If a phase channel is wired incorrectly, you can swap the phase to another channel by changing an internal Recorder setting using the PDA, and then reconfirm correct readings.

- Internal Uninterruptible Power Supply (UPS)

An internal NiMH (Nickel-Metal-Hydride) battery pack and charging system maintain data capture continuity through power interruptions of approximately 5 minutes or less.

• Automatic disturbance capture

The Recorder uses an automatic, self-learning threshold routine, which means you do not have to set any event threshold limits before you start recording. You detect and display power quality events (disturbances) using the Power Analyze software on a PC after the event has been captured. You define thresholds for events after data is stored on the PC. This is called the "event detector" in the software. It does not make permanent changes to the data file, so you can experiment with different thresholds after the fact without worrying about losing data.

With these features, there is little else required to set up and start recording the data to conduct a power quality survey. Should you want to extensively analyze collected data, the procedures described later in this manual review the transfer of data from the Recorder to the PDA, and finally to a PC. Data may then be analyzed using Power Analyze on a PC. Extensive online help is provided in the Power Analyze software on the product CD shipped with the Recorder.

Installing the Power Recorder at a Facility

This section describes the steps you need to take to set up the Recorder at a facility and begin a recording session.

Work Flow

There are three distinct stages for a recording session.

- Setup

Setup, hookup, and verification of connections and measured signals. This is when you will want to clear the Recorder memory (not required, but best practice because data download when finished only contains your new data). This is a good time to change any recorder settings. Edit the measurement description now or after downloading the measurement data and insert annotations and/or an optional START mark into the recorded data stream. Annotations are messages or notes you insert into the data stream during a recording session.

• Interim checkup, mid-recording session

At this time, you may want to re-check all the live input signals, and download the data recorded since the beginning of the recording session. This does not interfere with ongoing recording in any way. Annotation capability is always available during the recording session.

• End of recording session

You can re-verify if desired, correctness of live data and then download data, power off the Recorder, and pack up for transport.

Installing the Recorder

1. Position the Recorder within 2 m (6 ft) of the monitoring location.
2. The Recorder can be set on the floor or a table, or attached and secured to a pole or other mounting surface. The Recorder can be oriented vertically or horizontally.
3. Connect the Recorder to a 100 to 240 V ac power source, 50 or 60 Hz.
4. Plug the power cord into a properly-grounded wall outlet.

Caution

To avoid damage to the Recorder:

• Ground the chassis as appropriate according to your power connection before you do anything else.
• Connect the power cord to the Recorder using the appropriate supplied adapter.
• Connect the power cord to a properly grounded wall outlet.
• Be sure to plug the power cord into the Recorder panel BEFORE connecting it to an outlet.

After a minute, or two, all LEDs should flash ON, then OFF, and then each should turn ON and OFF in sequence. The LEDs will then remain on if you make secure test lead connections and there is sufficient voltage and current.

1. Turn on the PDA and tap the Power View icon to launch Power View.

If a Recorder is within range and is not password protected, it should appear in the drop down menu just below the main title bar on the PDA. You may need to select Browse for recorder when first connecting. Select the recorder you want to browse to with the PDA stylus. Upon selection, the Home screen for live data appears.

If more than one Recorder is within range, these will appear in the drop down menu list.

1. If you have previously established password protection for the Recorder, you must type the correct password in the Password text box and click OK. (Password protection is established for a specific Recorder using either the Setup Password menu in Power View or the Power Analyze software).

Connecting the Recorder to the Wiring

After you have set up the Recorder you are ready to connect the voltage leads and current probe or flexi-probes to the power network being tested. Refer to the Power Type diagrams provided on the PDA or in this manual.

⚠ Warning

To prevent possible electrical shock, Flexi-probes should not be applied or removed from hazardous live conductors.

In most cases, you should install the current probes first. Because they are clamped around wires, current probes are usually more secure than voltage probes. Examine the conductors you are about to connect to and determine if you should attach the current probes to the phase wires or busbars before you connect the voltage probes.

1. Select and attach the appropriate current probes to the Recorder.
2. Select and attach the appropriate voltage test leads and probes to the Recorder.

Note

If your power connections require potential transformers (PTs) or current transformers (CTs), you can use the ratio settings in Power View to set the Recorder to display readings as they exist on the primary side of the PT and CT (for example, 12000 V).

1. Connect the Recorder to the wiring by first connecting the measurement ground test lead to the distribution system ground, and then the neutral probe to neutral.

2. Connect the ground current probe to the distribution system ground and the neutral current probe to neutral, with the arrow on the current probe pointing towards the load (away from the source) in each case.

3. Connect the remaining current probes to the power network.

• The arrow on the current probe should point toward the load.
- Use the color-coding on the leads to help you connect the probes to the correct phases, neutral and ground.

1. Connect the remaining voltage probes.

Note

Make sure the voltage probes and current probes are paired correctly, Phase A (L1) voltage to Phase A (L1) current and so forth. Calculations are made in pairs and cannot be changed after data is recorded. The leads for the voltage probe and current probe of the same color should be attached to the same phase wire or busbar.

1. Check the LED for each phase to make sure a connection is established.

2. When a phase LED is ON or lighted, you know that the connection is active and that voltage and current is within the normal range.

3. When a phase LED is BLINKING, you are connected but the voltage or current is exceeding the normal range or exceeding the range of the probe that you are using.
4. When a current LED is OFF or unlit, there is insufficient current present in the line.

Verifying Your Connection

Before you leave the Recorder to accumulate data at the facility, double-check the connections.

• Make sure the current probes are secured and completely closed around the conductors and that the voltage and current LEDs are steady-on.
• Use the PHASOR screen on the PDA or PC to verify that the voltage and current connections are correct. You can swap the connections using Power View if they are incorrect.

Finishing Up

After making any corrections to the connections, recheck the PHASOR diagrams to confirm your connection. Make sure the nominal voltage, nominal line frequency, and power type (delta, wye, other) are correct before you leave the Recorder. It is a good practice to insert a Start Mark when you are finished with all settings so you can download data and ignore useless readings and events common at the beginning probe connecting activities. You can also use the “Erase Memory” function and measurement

descriptions such as company, name, and measurement purpose. This can be done at this point or after downloading the measurement data.

Managing Recorded Data

Recorded data resides in the Recorder on an internal non-physically accessible flash memory circuit. The transfer of recorded data to the SD card in the Recorder's SD slot is automatic when you insert the SD card or you request a download action using the PDA. Downloading to a PC running Fluke Power Analyze Software (included) using the Ethernet cable is recommended and the fastest way to retrieve data from the Recorder.

Note

To stop the automatic copy from the SD card memory, go to Menu >Tools >1750 Internal Memory or Menu >Tools >1750 SD Memory.

It is never technically necessary to erase internal memory. When the Recorder has new data to record, it does so automatically, overwriting the oldest data (circular memory). You can erase internal memory for security reasons, or if you want to simplify what you will be seeing in the download data screen. The start and end times will represent one recording session when old data is erased.

Note

Data is not removed from internal Recorder memory until you erase it using Power View software on the PDA or Power Analyze software on your PC.

Power Type Diagrams

The wiring illustrations included cover the standard power configurations that are selectable in Power View or Power Analyze software. The diagrams are provided as an aid in making the correct test lead connections. Power type diagrams are also included on your PDA and can be referenced when you are setting up nominal power on the Recorder.

Available power type settings are:

• One-Phase Plus Neutral (Figure 4)
• One-Phase IT No Neutral (Figure 5)
• One-Phase-Split Phase (Figure 6)
• Three-Phase Wye (Figure 7)
• Three-Phase Delta (Figure 8)

Communicating with the Recorder Using Power View

The PDA serves as your control panel for the Recorder. The Power View software installed on the PDA is designed to function as a remote front panel for the Recorder, since the Recorder itself is a “black box” with no integral display or external controls other than status LEDs. With Power View installed on the PDA, you are relieved of the burden of having to carry a laptop and Ethernet cable to a remote site when setting up the Recorder, checking its progress, or finishing a monitoring session.

You can alternatively connect to a Recorder from a PC directly using an Ethernet cable or remotely over an IP network. You can then use Fluke Power Analyze to set up the Recorder, view power measurements wherever the Recorder is installed, or download data from the Recorder.

Power View communicates with the PDA using a wireless controller radio interface. There is no provision for a hardwired PDA interface to the Ethernet port on the Recorder. After data is recorded and downloaded to a PC, you can analyze the recorded data using the Power Analyze software.

Navigating in Power View on the PDA

The Menu Bar on the bottom of the Power View screen allows you to quickly and easily configure a Recorder, view live data, and transfer data to the Secure Data (SD) card for viewing and analysis on your desktop computer using the companion Power Analyze software.

Power View Menus

Live

Brings up a list of the live detail views: Scope, Meter, Phasor, Harmonics, and Trend. There are configurable detail views of each type of screen available by tapping the sector of interest or the Live menu. Once a detail view is selected, navigation to all available detail views is accomplished using the Live menu.

Menu > Tools opens the Data Memory Management screens and the Shut Down command to turn off the Recorder. Data Memory Management has screens for downloading to the SD card inserted in the Recorder, erasing the Recorder's internal memory, and erasing the SD card files.

Menu > 1750 Setup brings up the setup screen that allows you to configure the Recorder and set recording period information. Using this function, you can tap the appropriate icon to set the following:

• Clock
• Probe Detect
• IP Address
  • Measurement Description
• Nominal Power
• Phase Swap
• Volts/Current Ratio
• Recorder Name/Password
• Snapshot Period
• Language

Icons on the Menu Bar

and are used to toggle between voltage and current wave forms. Tap either V or A and then Live>Home to see each parameter's detailed data. The PHASOR screen always shows both V & A (volts and amps). is replaced with on the detail views, as voltage and current data can be viewed simultaneously.

In all the detail live view screens, a line selection menu is available using the button at the bottom. This is a checkbox that is used to select the voltage and current channels you want to display.

[NO TEXT]

The Snapshot icon triggers the Recorder to capture high-resolution waveform data and save it in the recorded data stream. This waveform capture is identical to the snapshots taken automatically when you set the “snapshot period” in the 1750 Setup menu.

[Non-Text]

This icon brings up the Annotate screen. Use the annotate menu to enter text or to insert a file name and load it into the recorded data stream in the Recorder. Annotations can be used to make notes, or to insert a file name of an image or audio file. You can enter multiple start and stop annotations. START and stop annotations are not paired and are not restricted to being used as literally “start” and “stop”. Annotations are often done at the start of a power recording session.

azd15f.eps

Home Screen

The Home screen is the top-level screen, accessed when you start Power View or when you tap Live and then Home on the Menu Bar.

The Home screen contains a 1.5 cycle waveform screen, a digital meter screen, and a PHASOR screen. The parameters shown in this screen are not configurable. All phases are shown simultaneously, either all voltage or all current.

If no Recorders are within range, the following screen appears:

azd111.bmp

azd112.bmp

If more than one Recorder is within range, the Recorder selection screen appears. An asterisk preceding the Recorder name means that unit is password protected. If your recorder is not listed, but in range, press "Search New Devices" to update the list.

azd113.bmp

If the selected Recorder is not password protected, the Home screen appears. If password protection is set, the Password screen appears instead.

azd114.bmp

If the password is incorrect the password text field is cleared and then you can re-enter the password. When the password is accepted, the Home screen appears.

Note

A screen to set up password protection for a Recorder is provided in the 1750 Setup menu.

Downloading Data and Erasing Memory

Use the Data menu options to manage the Recorder memory and download recorded data to the SD card plugged into the Recorder's (not the PDA) SD card slot. You are downloading recorded data from the flash memory to an SD card in the Recorder. You can later copy the data to your PC for review using the Power Analyze software.

Auto Download

The Auto Download feature copies all recorded data to the SD card without a PDA or PC. Auto Download starts when you insert the SD card and have no connection to Power View or Power Analyze. The SD card status indicator flashes while a copy of the data moves to the SD Memory card.

Note

Do not remove the SD card while the SD status indicator is flashing. It may result in corrupted data integrity of the SD card. The SD card can be safely removed when the SD status indicator is off.

The automatic download can be aborted with Power View by either tabbing on Menu>Tools>1750 Internal Memory or Menu>Tools>1750 SD Memory.

If the download does not start automatically:

1. Verify that neither Power View nor Power Analyze is connected to the device.
2. Watch the SD status indicator. As soon as an SD card is inserted, the indicator flashes green for a short time. This is the indication that the device has recognized the SD card. If nothing happens the SD card is not compatible with the Fluke 1750.
3. Check if the SD card is write-protected. Make sure the slider on the card is not in the LOCK position.

If the SD status indicator flashes when the SD card has been inserted but it does not flash for a longer period of time (>1 second) the available space might be insufficient. Use a new card without any files or delete files on the SD card with the use of the PDA or a card reader.

PDA Download

Tap 1750 Internal Memory in the Data menu to view the Download screen.

azd116.bmp

The Download screen shows a three-phase rms V strip chart with date and timescale shown. This represents the data in the Recorder internal memory. The default settings of the start and stop times is everything in memory. To download ALL, tap the Write to SD button. If you want to trim off data that contains partial information because probes were being connected, select the START mark annotation (if one was entered by the user) as The gray cursor lines right and left with triangular arrowheads at the bottom of the screen show the start and stop times currently selected for download. Green and red flags are START and STOP mark annotations inserted during the recording session. Yellow flags are file name annotations inserted during the recording session, or setup parameter changes that change the data significantly, such as nominal voltage or power type.

azd117.bmp

If the SD storage card already contains data files, it may not have room for the new download. Power View alerts you to this condition and asks if you would like to erase the SD card before downloading.

azd107s.bmp

You can also access the SD card to delete files by selecting Menu>Tools>1750 SD Memory.

You can delete files as necessary, and when satisfied that there is room on the card, proceed to write the selected internal Recorder memory data to the SD card.

azd108s.bmp

When there is room on the card, a message confirming the download will appear.

azd118.bmp

You can also tap the Erase 1750 Memory from the Data menu option which is available under Menu, and tap the Erase All button to erase all power quality data stored in the Recorder. Even then, if you want, you can leave old data in Recorder memory. It will be overwritten automatically when you start your next Recorder session, so it never has an adverse effect on recorded data quality or quantity.

azd109s.bmp

When you choose to Erase All, the following popup caution "Are you sure?" appears on the screen.

azd119.bmp

Note

You can also download data by connecting your PC directly to the Recorder with an Ethernet cable and run Power Analyze in the 1750 Live mode. All of the functions (controller, PDA, and Power View) are duplicated in 1750 Live mode.

Viewing Live Data

The Live menu is used to view live data on the circuits on the circuits for example, Scope, Meter, Phasor, or Harmonics.

azd120.bmp

Scope Screen

The Scope screen shows 1.5 cycle waveform data for the volts and amp lines selected in the check boxes on Phase View screen. Tap the Phase icon ( ) to display the Phase View screen.

azd121.bmp

Meter Screen

The Meter screen shows numeric readings for all selected phases.

azd122.bmp

Phasor Screen

The Phasor screen shows voltage (long arrows with solid arrowheads), current amplitudes, and phase angles. This screen is used to verify proper test lead and current probe connections. You can use the V and A arrows on the upper right of the screen to change the scaling of voltage and current on the PHASOR diagram.

You can easily correct an erroneous Recorder connection by going directly to Menu\1750 Setup\Phase Swap (☑) and using the Recorder to internally invert a CT, swap a voltage or CT phase, or modify a scaling parameter, then return to the screen to verify that the correction has been made. There is no need to touch the cables. See “Phase Swap” later in the manual for additional information.

azd123.bmp

Harmonics Screen

The Harmonics screen shows the magnitudes of the selected phases of V and I. The scale is % of nominal.

The slider control displays harmonics of a higher order up to the 50^th . The V and A scaling arrows are on the screen in the upper right.

If the power type is delta, V phases are AB, BC, and CA (L1L2, L2L3, L3L1 is available as a localized European labeling scheme). If the power type is Wye, V phases are AN, BN, CN, and NG. (N = neutral, G = ground).

124.bmp azd

Trend Screen

The Trend screen shows live data being recorded as a strip chart display of the selected phases of voltage or current. This moment in time is visible on the right side of the graph.

The traces fill the screen in 10 minutes, and continue FIFO (first-in, first-out). This feature is intended to paint a picture of the short-term stability of the power system. The V and A scaling arrows on the upper right work like the scaling arrows on the PHASOR screen.

azd125.bmp

Viewing Phases

In all the detail Live View screen, a line selection menu is available using the button at the bottom. The Phase Selection screen reveals check boxes for selecting the voltage and current channels you want to display.

azd126.bmp

Setting Up the Recorder

To adjust the settings of the Recorder, tap Menu>1750 Setup.

azd127.bmp

The Setup screen shows setup options.

azd140.bmp

From the Setup screen, you can adjust either the recording period information or the Recorder settings. Tap an icon on the Setup screen to view or configure:

• Clock
• Probe Detect
• IP Address
  • Measurement Description
• Nominal Power
• Phase Swap
• Volts/Current Ratio
• Recorder Name/Password
• Snapshot Period
• Language

Setting the Clock

Use this feature to set the PDA clock or clock to synchronize the Recorder with the PDA clock.

azd128.bpm

Probe Detect

This screen shows the types of probes attached to the Recorder current inputs. Current probes are automatically detected.

azd129.bmp

Setting the IP Address

Select Obtain Address Automatically unless your company's IT department has specific requirements that require assigned IP addresses. When this mode is active, the assigned IP Address and Subnet Mask show in gray. The Default Gateway address is not supported and this field always defaults to 0.0.0.0.

azd130.bmp

Adding a Measurement Description

Click on the arrow and select one of the six available captions from the list box and enter the text in the text field below. The number of characters is limited to 50. Click on Insert to apply the changes.

You may change or delete the caption. The maximum possible length for caption text is 20 characters.

To apply changes, click on Apply.

Click OK to close the window and send the measurement description to the device.

azd141.bmp

Configure Nominal Power Values

This window contains the setup for Power Config, Nominal Voltage, and Frequency. It is important to correctly configure these values before the measurement as some calculations are based on these settings and cannot be recalculated after the measurement has been performed. Click on the 3-phase delta icon to display the wiring diagram of the selected topology. The list box of nominal voltage levels contains commonly used voltage levels. Different voltage levels may be entered if required.

azd131.bmp

Using Phase Swap

Rather than having to change the physical connections to the power system, use the Phase Swap feature to make a software-selectable correction without physically switching the cable. You can select from the following:

• Swap any voltage input
• Swap any current input
• Invert any current input clamp

The screen shows check boxes to invert any current probe. Current probes are directional, and selecting “invert” has the effect of removing the probe and turning it around.

If the power type is delta, V phases are AB, BC, and CA (L1L2, L2L3, L3L1 is available as an optional setting). If the power type is Wye, V phases are AN, BN, CN, and NG. (N = neutral, G = ground).

Setting the Volts and Current Ratio

Use this menu to add a ratio factor to the voltage or current input on each phase.

Changing the first “1” in each case if there is a potential transformer in series with the voltage connection such as when you want to monitor a medium-voltage network using PTs and CTs to scale the voltage and current to a convenient level for measuring instruments.

The current ratio applies a ratio to the current input in order to show the current present on a medium-voltage network. This feature is intended to be used for sensing low levels of current to represent the much higher levels on the primary side at a substation or step-down transformer that has built-in metering current transformers.

azd134.bmp

Assign Recorder Name and Password

Use this feature to assign a name identifier to the Recorder and to establish a password for the Recorder. This naming feature is designed to help you keep track of which Recorder is in use. The Recorder name is later associated with the data file that you download from the Recorder.

azd132.bmp

Setting the Snapshot Period - Periodic Waveform Capture Setting

Use the Snapshot Period screen to program the Recorder to take automatic power conditions readings which are then stored in the recorded data stream. These snapshots contain a phasor diagram, waveforms of current and voltage, harmonics profiles, and other data.

• None
• 10 minutes
• 30 minutes
  • 1 hour

Note

You can take a snapshot manually at any time at any time while connected over the wireless link to a Recorder. Press the Waveform icon 📋 on any of the View screens to take a snapshot. The message, "Snapshot Acquired" confirms that a snapshot was taken.

azd135.bmp

azd139.bmp

Change Display Language and Phase Identifier

Power View features a localized user interface for English, German, French, Spanish, Chinese, and Italian. Select one of these languages and select your preference of phase identifier as A, B, C or L1, L2, L3. A restart of Power View is required to apply these changes.

azd142.bmp

Working with Annotations

Annotations are optional markers that can be inserted by the Recorder operator to flag a particular point in the data when recording. They are usually inserted on using Power View with the wireless PDA.

azd137.bmp

There are five types of annotations:

- START annotation (green)

The START annotation can be used to signify where important data begins. For example, the operator might want to establish a start annotation after having finished all probe connections and instrument setup, to indicate that any preceding data was preliminary.

Note

You are not limited to using the START and STOP annotations in pairs, or to show a range of data. You can use each as many times as desired to mark a particular point during recording.

• STOP annotation (red)
  The STOP annotation can be used to signify where important data ends.
• File annotation (yellow)
  File annotations contain the name of a picture or audio file relevant to the data. See “Using Image or Voice Annotations” later in this manual.

- Text annotation

Text annotations contain a text note.

• Power Configuration Change annotation

Power Configuration Change annotations are inserted by the system when a change is made to the Power Configuration in the Recorder. These markers only display in the Download dialog box.

To show or hide annotation markers:

- In the Volts/Amps/Hz or Events view, check or uncheck the Annotations option on the view controls.

To open an annotation:

- In the Volts/Amps/Hz view, Events view, or Download dialog box, click on the annotation.

If the annotation is associated with an audio (.WAV) or image (.jpg) file, the application associated with that file will start and open the file. If the file is not in the default directory \My Documents\Fluke\Power Analyze, a dialog box opens so that you can navigate to the file.

Note

If clicking on an annotation marker does not seem to do anything, the Zoom box is probably selected in the graph toolbar, instead of the Select tool. Click the Select tool and then select the annotation.

To see overlapping annotations:

Sometimes annotations are so close to each other that they actually overlap on the Volts/Amps/Hz reference graph. When this is the case, if you click on overlapping annotations, a menu opens and you can select either Open, to open the annotation now on top, or Select Next Overlapping Annotation, to bring the next one to the top.

• To open the annotation now on top, choose Open.
• To bring the next annotation to the top, choose Select Next Overlapping Annotation. To then open that annotation, click on it again and choose Open.

Note

To see overlapping annotations more clearly on the Volts/Amps/Hz reference graph, move the selection cursors so that they just surround the area that contains the overlapping illustrations. The Detail graph adjusts as the cursors move, zooming in to show the area between the selection cursors. You can now see the annotations separately.

Using Image or Voice Annotations

While you are monitoring data with a Recorder, you may find it helpful to take a picture that relates to the power quality data you are recording, or to record verbal comments as you observe the conditions or review the data being measured. You can then associate the image or recording with the data being recorded by adding annotations that reference them.

The PDA includes a microphone for recording notes which are saved as .WAV files, and an optional camera accessory is available on the PDA which will capture images as .jpg files.

You can associate both images and audio files with the data being gathered in the Recorder by inserting annotations and specifying the name of a .WAV or .jpg file. After you download data from the Recorder, you can then move the image and audio files to the PC along with the recorded data (.odn) file.

Note

You can also associate other types of files with the annotation. For example, if you had a .MPG file with a movie, or a .DOC file with associated information. You can enter any file name using this annotation method.

Inserting Image or Voice Annotations

1. Set up the Recorder and begin monitoring.
2. Using your PDA-cam (not available in standard PDA supplied) or another camera, take a picture of what you want to capture.
3. Click the Annotate icon to display the Annotate screen.
4. Move the image or audio file to a location that will make it easier to Transfer it to a PC later, when you download and move the recorded data file to your PC. Place the file into the synchronization folder on your PDA, so that it will be automatically transferred into the sync folder on the PC the next time you dock the PDA.

Turn off the Recorder

The Recorder always has the UPS enabled to allow a 5-minute pass through time on a voltage interruption. When you pack the Recorder for transport, you have the option to shut down the Recorder and disable the UPS before unplugging the power cord.

To turn off the Recorder:

1. Select Menu>Tools>1750 Shut down...
2. Confirm the warning message.
3. Wait until the Power LED is solid green.
   The power cord can be safely unplugged.
