Operation 6-1 AC Voltage Warning Function DANGER ● Never make measurements with the battery compartment cover removed. CAUTION ● Never press the test button if the live circuit warning lamp is lit or the warning buzzer sounds. This may damage the circuit. Voltage check can be made with the range selector switch at any position. -
Page 13: Insulation Resistance Measurement
6-2 Insulation Resistance Measurement DANGER ● Always test the circuit or equipment to ensure it is surely de-energized before measurement according to the instruction of 6-1. ● To avoid electrical shock, measurements must be performed on de- energized circuits only. ●... - Page 14 ④ Check the circuit under test is not energized as follows. Connect the test probe to the circuit under test and read a voltage value. If the circuit is live, the meter indicates the voltage, the live circuit lamp is lit, and warning buzzer sounds.

required test voltage when providing a steady state current of 1mA. The minimum allowable resistance level is 0.25MΩ for the 250V test, 0.5MΩ for the 500V test and 1MΩ for the 1000V test. ● Principle of Insulation Resistance Measurement Resistance value can be obtained by applying a certain high voltage to the resistance (insulation resistance) and measuring the flowing current. - Page 16 CAUTION ● Never press the test button if the live circuit warning lamp is lit or the warning buzzer sounds. This may damage the circuit. ● In case that an additional operating circuit is connected in parallel to the circuit under measurement, the measurement error might be caused due to the effects of impedance of the circuit connected in parallel or transient current.
