6.2 Isolamendu-erresistentzia neurtzea
The BT-6688B measures insulation resistance from 0.1 MΩ to 200 GΩ with selectable test voltages.
- Ensure the meter is OFF and the circuit under test is de-energized.
- Insert the red test lead into the "L" terminal and the black test lead (with the large clip) into the "E" terminal.
- Clamp the large test clip to one end of the object to be tested (e.g., ground or neutral).
- Select the desired insulation test voltage (100V, 250V, 500V, 1000V, 2500V, or 5000V) using the rotating switch.
- Connect the red test probe to the other end of the object to be tested (e.g., live conductor).
- Press the "TEST/STOP" button to initiate the test. The "HV" indicator will light up, indicating high voltagirteera.
- Read the insulation resistance value displayed on the LCD.
- Press "TEST/STOP" again to stop the test and discharge the circuit.
