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.

① The presence of AC voltage can be detected. This function operates

automatically when the test button is not depressed, i.e., in the up position.

NOTE:This tester has not been designed to indicate the presence of an
external DC voltage.

② Connect the earth clip of the test probe (black) to the EARTH and the line

probe (red) to the LINE side of the circuit under test.

③ Take the reading on the AC voltage scale.

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.

●

When the test button is pressed with the range selector switch in the

insulation position, take care not to touch the tip of the test probe and the

circuit under test where a high voltage is present in order to avoid possible

shock hazard.

●

Never make measurement 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.

Conduct the voltage warning check before measurement to ensure that the

circuit under test is de-energized.

① Check the voltage which can be applied to the circuit under test and set the

range selector switch to the desired nominal output voltage range.

② Connect the earth clip of the test probe (black) to the earth terminal of the

circuit under test.

③ Put the tip of the line probe (red) to the circuit under test.
