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.
