5. Operating Instructions

5.1 Insulation Resistance Measurement

To measure insulation resistance:

1. Ensure the device under test is de-energized and isolated from all power sources.
2. Connect the test leads to the device under test as per the specific test requirements (e.g., between conductor and ground, or between two conductors).
3. Turn the rotary switch to the desired insulation test voltage (500V, 1000V, 2500V, or 5000V). The display will show '000' or a similar standby indication.
4. Press and hold the TEST/STOP button to begin the test. The HV indicator lamp will illuminate, indicating high voltage output.
5. Read the insulation resistance value on the LCD display.
6. Release the TEST/STOP button to stop the test. The HV indicator lamp will turn off, and the device will automatically discharge any residual voltage.
7. For continuous measurement, you can press and hold the TEST/STOP button.

5.2 AC Voltage Measurement

To measure AC voltage:

1. Turn the rotary switch to the '750V AC' position.
2. Connect the red and black test leads across the circuit or component where you want to measure AC voltage.
3. The AC voltage reading will be displayed on the LCD.

5.3 Using the Backlight and Data Hold

• Backlight: Press the LIGHT button to turn the display backlight on or off. This is useful in dimly lit environments.
• Data Hold: Press the HOLD button to freeze the current reading on the display. Press it again to release the hold function and resume live readings.

6. Maintenance

6.1 Cleaning

• Wipe the meter's casing with a damp cloth and mild detergent. Do not use abrasive cleaners or solvents.
• Ensure the meter is completely dry before storage or next use.

6.2 Battery Replacement

When the battery indicator appears on the LCD, replace the batteries promptly to ensure accurate measurements. Refer to Section 4.2 for battery installation instructions.

6.3 Storage

• If the meter will not be used for an extended period, remove the batteries to prevent leakage and damage to the unit.
• Store the meter in a cool, dry place, away from direct sunlight and extreme temperatures.
• Use the provided carrying case to protect the meter from dust and physical damage.
