5.1 Powering the Meter

1. Set the function switch to any position to switch on the meter.
2. If the battery indicator 📄 shows that the battery voltage is low or if the meter does not power on, replace the battery. See section 6.2 Battery Replacement.

5.1.1 Auto Power Off

The meter enters sleep mode after 30 minutes of inactivity. The meter beeps three times 20 seconds before powering off. Press any button or turn the Rotary Switch to prevent the meter from powering off. The auto power off time-out is then reset.

5.2 Manual AC/DC Selection

When measuring voltage, press the MODE button to select AC or DC voltage.

5.3 Auto Range

Auto-Range is the only mode of operation for Capacitance; ranges are automatically selected by the meter. Insulation Resistance tests allow for voltage test selection using the rotary switch.

5.4 'Smart' Out-of-Range Warnings

If the input is over/under the full-scale range, the display will show >x or <x, where x is the high or low end of the full-scale range.

5.5 Data Hold and Auto-Hold Modes

These two modes are discussed in detail below. In the Settings menu, if Auto-Hold is set to OFF, the meter will operate in the standard Hold mode. If Auto-Hold is set to ON in the settings menu, the meter will operate in the Auto-Hold mode.

5.5.1 Data Hold Mode

In Data Hold mode, press the HOLD button to capture the measurement that is shown on the main display.

To exit the Hold mode, press the HOLD button again.

5.5.2 Auto-Hold mode

If Auto-Hold mode is switched ON in the settings menu, press the HOLD button to activate Auto-Hold mode (the 'H' display icon will appear flashing). In Auto-Hold mode readings are

captured in the say way as in standard Hold mode. The difference is that the captured reading, displayed on the smaller, secondary display digits, will update whenever a reading 50 digits higher or lower than the captured reading is measured. To exit the Auto-Hold mode press the HOLD button.

5.6 Voltage Measurements

1. Set the function switch to the position.
2. Insert the black probe lead into the COM terminal and red probe lead into the V terminal.
3. Use the MODE button to select AC or DC voltage measurements.

5.7.1 PI/DAR Test

Note: PI (Polarization Index); DAR (Dielectric Absorption Ratio)

1. Select the PI or DAR test as described in section 5.12.1 Selecting modes.
2. Press the TEST OK button to test.
3. Press the MODE button to show the test time at the upper reading area. (LCD will show CLOCK icon and the elapsed time). PI is a ten-minute test and DAR is a one-minute test.
4. The test will stop automatically, and the result (ratio) will be shown on the main display area. The PASS/FAIL LED will indicate the test result (Green for PASS, and Red for FAIL).

5.8 Earth Bond Resistance Measurements (ZERO Ω)

1. Move the function dial to the Earth-bond resistance position (ZERO ); the Earth-bond

resistance icon will appear.

1. Insert the black probe lead into the COM terminal and red probe lead into the ZERO/Ohm/Insulation terminal.
2. Before testing, short the ends of the probes and press the MODE button. The ZERO icon will appear on the display and the offset value will be stored. If the test leads are not shorted or if there is residual resistance, the display will show the >2.00 ohms (this indication could be due to faulty leads, improper test lead insertion, or meter problem. Tests should not be attempted until root cause of the high resistance is determined.
3. Connect the test leads to the Device under test.
4. Press TEST OK to run a test.
5. To lock the test ON, press the HOLD/LOCK button (the LOCK icon will appear) and then press TEST OK to test continuously.
6. Press TEST OK again to stop the test.
7. Note that the Earth Bond Resistance Measurement mode can also be used to measure standard resistance to 40kohms

NOTE: The 99-point Data Record memory function cannot be activated in the usual way while using the Earth Bond Resistance function (since the TEST OK button is used for testing in this case and not for saving readings). The last reading, however, is held on the display and can then be saved as described in the Extended Functionality section below under Section 5.12.7 Data Recording Mode.

5.9 Continuity Test

Warning: Do not do diode, resistance or continuity tests before removing the power from capacitors and other devices under test during a measurement. Injury to persons can occur.

3. Insert the black probe lead into the COM (negative) terminal and the red probe lead into the positive V terminal.
4. Touch the tips of the probes across the diode or semiconductor junction under test. Make a note of the value on the display.
5. Reverse the polarity of the probes, by interchanging the probe test locations.
6. Touch the tips of the probe across the diode or semiconductor junction under test. Make a note of the new value on the display.
7. The diode or semiconductor junction can be evaluated as follows:

If one of the readings displays a value (Typically 0.4.00 to 0.900 V) and the other reading displays a value (-0.400 to -0.900 V), the component is good.

If both readings display OL, the component is either open or shorted.

Use Continuity mode to determine if it is open or shorted.

5.12.6 Silent Mode

In Silent mode, the alert beeper is disabled. Silent mode does not affect the continuity beeper.

Select and enable Silent mode as described in section 5.12.1 Selecting modes.

5.12.7 Data Recording Mode (99-point)

The meter has 99 memory locations for the storage of measurement data.

Select and enable MEM mode as described in section 5.12.1 Selecting modes.

Use the arrow keys to cycle through the mode options: SAVE, LOAD, and CLEAR shown on the secondary display.

SAVE: The data on the main display is saved to a memory location indicated by the '88' in the upper display area.

LOAD: The data stored in the memory location (identified by the '88' indicator) is displayed.

Use arrow keys to scroll the memory locations. Use the button to exit the LOAD mode.

CLEAR: The data in all memory locations is erased.

5.13 Keypad Lockout

In Lockout mode the meter ignores all button presses except HOLD. The auto power off function, see section 5.1.1 Auto Power off, is disabled in Lockout mode.

Press and hold the HOLD/LOCK button for 3 seconds to enter/exit the lockout mode. In lockout mode, the lock indicator is displayed. Do not confuse Lockout mode with the test lock feature used for continuous Insulation Resistance testing (see Section 5.7 Insulation Resistance Measurements).

5.14 Streaming Measurement Data using METERLINK

5.14.1 General

You can stream measurement data to a mobile device using the METERLINK app. The app is available from the Apple Store ^® (iOS) or from Google Play ^™ (Android).

5.14.2 Procedure

1. Download the METERLINK app to your mobile device and open the app.
2. Power the meter and select the desired measurement mode.
3. Press the meter's Bluetooth button ✪ to enable communications.
4. Follow the instructions and prompts on the METERLINK app screens.

6.1 Cleaning and Storage

Clean the meter with a damp cloth and mild detergent; do not use abrasives or solvents.

If the meter is not to be used for an extended period, remove the batteries and store them separately.

6.2 Battery Replacement

The Battery symbol flashes with no 'bars' when the batteries have reached a critical level of 7.0V. The symbol stays active and visible while the LCD is powered.

The meter displays readings within specifications while the low battery indicator is on. When this is no longer possible, the display must be blanked. The meter powers off before it displays an out of tolerance voltage.

1. To avoid electrical shock, disconnect the meter if connected to a circuit, remove the probe from the terminals, and set the function switch to the OFF position before attempting to replace the batteries.
2. Unscrew and remove the battery compartment cover.
3. Replace the six standard AAA batteries, observing correct polarity.
4. Secure the battery compartment cover.

Never dispose of used batteries or rechargeable batteries in household waste. As consumers, users are legally required to take used batteries to appropriate collection sites, the retail store where the batteries were purchased, or wherever batteries are sold.

6.3 Fuse Replacement

The fuse accessed via the battery compartment cover. The fuse is rated 440mA/1000V, ceramic fast blow with a minimum Interrupt Rating of 10kA.

6.4 Disposal of Electronic Waste

As with most electronic products, this equipment must be disposed of in an environmentally friendly way, and in accordance with existing regulations for electronic waste. Please contact your FLIR Systems representative for more details.
