Insulation Resistance Test
Manual Test
1. Connect the Black Earth test lead to the Earth
connector and the Red test lead to the LINE and
COM connectors.
2. Set the Function Selector switch to the desired
insulation test voltage.
3. Connect the test leads to the device under test.
4. Press and hold the PRESS TO TEST button to
run the test. The buzzer will beep during the
test.
5. Read the measured value on the LCD display.
6. Release the button to end the test and
discharge the device. While the circuit is
discharging, the
icon will
flash. The measured value, HOLD and the
measurement time will remain in the display.
7. Press the STOP button to clear the display.
8. Set the Function Selector switch to OFF position and remove the test leads from the circuit.
Locked Test
1. Repeat steps 1 to 3 as above.
2. Press and turn the PRESS TO TEST button to the lock position to run the test. The buzzer will
beep during the test.
3. Read the measured value on the LCD display.
4. Rotate the PRESS TO TEST button to the PRESS TO TEST position to end the test and
discharge the device. While the circuit is discharging, the
icon will flash. The
measured value, HOLD and the measurement time will remain in the display.
5. Press the STOP button to clear the display.
6. Set the Function Selector switch to OFF position and remove the test leads from the circuit.
