6-1 AC Voltage Measurement (Mains Disconnection Check)

An AC voltage range is provided for mains voltage measurement. If any voltage is

present on the circuit under test in insulation resistance measurement, the display

also reads the voltage before the test button is pressed.

Note:

On any range, the instrument measures and displays AC voltage while the test

button is not depressed. However, when you simply make AC voltage

measurement, not mains disconnection checks, the AC voltage range should be

used. This will avoid possible damage to the circuit under test by inadvertently

pressing the test button or the remote control switch to apply a high voltage.

DC voltage can be measured with the AC voltage measurement function. Take

the reading on the AC voltage scale and multiply it by 0.9. The reading does

not sense the polarity of DC voltage.

DANGER

When testing installation with a large current capacity, such as power

lines, make sure to make measurement on the secondary side of a circuit

breaker in order to avoid possible hazard to the user.

Never apply the instrument a voltage exceeding the limit for overload

protection.

In order to avoid possible hazard to the user, excise extreme caution not

to short live conductors together with the tips of the probes.

CAUTION

Never press the test button or the remote control switch during mains

disconnection checks to avoid possible damage to the circuit under test.
