(1) Check the voltage which can be applied to the circuit under test, and set the Function switch to a desired insulation resistance range. (2) Connect the Earth cord (black) to the Earth terminal of the circuit under test. (3) Place the tip of the Line probe (red) to the circuit under test. Then press the “PRESS TO TEST” button. The buzzer sounds intermittently during a measurement. (4) When the green LED illuminates, read insulation resistance on the outer scale (for high range). Use the inner scale where the red LED illuminates. # Caution Always turn off the Breaker ...
