5-3 Battery voltage check
(1) Connect the test lead to the instrument, and set the
Range switch to the BATT. CHECK position.
(2) Press the Test button or Remote control switch.
(3) If the meter pointer does not move to BATT GOOD, replace
the batteries as shown in Section 7 "Battery replacement".
CAUTION
Never keep the Test button pressed or locked during battery
check to avoid battery power drain.
5-4 Power-on-indication LED
On an insulation resistance range or BATT. CHECK range,
when the Test button or Remote control switch is pressed, the

6-1 AC voltage measurement (Mains disconnection check)
The AC voltage measurement function is available on any
ranges.
(1) Connect the Earth probe to the earth of the circuit under
test and Line probe to the other side. If the circuit is not
earthed, connect Earth probe to any appropriate conductor.
(2) Without pressing the Test button or Remote control switch,
take the reading on the AC voltage scale.
AC voltage measurement (Mains disconnection check)
The AC voltage measurement function is available on any ranges.
DANGER
¡
Never make measurement on a circuit in which the electrical
potential exceeds AC/DC300V in order to avoid possible shock
hazard. (Refer to Section 3. "Specification, AC voltage
measurement.)
¡
When testing installation that has a large current capacity, such
as a power line, be sure to make measurement on the
secondary side of a circuit breaker in order to avoid personal
injury.
¡
Do not press the Test button or Remote control switch during
voltage measurement.
¡
Never short live conductors with the tip of a probe to avoid
personal injury.
¡
Do not make measurement with the Battery cover removed.
