4. Setup

4.1 Battery Installation

1. Locate the battery compartment on the rear of the meter.
2. Open the battery compartment cover.
3. Insert the provided rechargeable batteries, ensuring correct polarity (+/-).
4. Close the battery compartment cover securely.
5. Charge the batteries using the provided charger before first use.

4.2 Connecting Test Leads

1. For most measurements, connect the black test lead to the "COM" (Common) input jack.
2. Connect the red test lead to the appropriate input jack based on the desired measurement function (e.g., "VΩHz" for voltage/resistance, "HV" for high voltage insulation testing).
3. Ensure connections are firm and secure before proceeding with any tests.

5. Operating Instructions

5.1 Power On/Off

Rotate the central dial to any function setting to power on the meter. To power off, rotate the dial to the "OFF" position.

5.2 Insulation Resistance Measurement

1. Connect the test leads to the "HV" and "COM" input jacks.
2. Rotate the dial to the desired insulation test voltage (e.g., 100V, 250V, 500V, 1000V).
3. Attach the test leads to the circuit or component under test.
4. Press and hold the TEST button to initiate the measurement. The display will show the insulation resistance value.
5. Release the TEST button to stop the measurement and discharge the circuit.

5.3 Dielectric Absorption Ratio (DAR) and Polarization Index (PI) Test

These functions assess the quality of insulation over time.

• DAR: Compares insulation resistance values at 1 minute and 30 seconds to assess insulation quality.
• PI: Compares insulation resistance at 10 minutes versus 1 minute to evaluate insulation performance.

1. Select the desired insulation test voltage.
2. Press the REL PI/DAR button to cycle through DAR and PI modes.
3. Press and hold the TEST button. The meter will automatically perform the timed measurements and display the calculated DAR or PI value.

6. Maintenance

6.1 Cleaning

Wipe the meter's surface with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure the meter is powered off and disconnected from any circuits before cleaning.

6.2 Battery Care

Recharge batteries when the low battery indicator appears. If the meter will not be used for an extended period, remove the batteries to prevent leakage.

6.3 Storage

Store the meter in a cool, dry place, away from direct sunlight and extreme temperatures. Utilize the provided carrying pouch for protection.
