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.

1. Set the function selector switch to AC600V. Connect the earth probe (alligator
clip on black lead) to earth of the circuit under test and the line probe (red) to
the other side as shown below. If the circuit is not earthed, connect the earth
probe to an appropriate conductor.
2. Do not press the test button or the remote control switch. Take the reading on
the AC voltage scale.
3. Set the function selector switch to the OFF position.

6-2 Insulation Resistance Measurement
The insulation resistance function is used for insulation check on electric
appliances, wiring systems, etc.
The circuit under test must be disconnected from mains and de-energized before
attempting to make measurement. Check the maximum voltage that may be
applied to the circuit under test.
Note:
¡In some cases, insulation resistance values are not stable, causing the reading
to vary during measurement.
¡The instrument may generate a high pitch tone during measurement, but this is
not a failure.
¡If the circuit under test has a large capacitive load, it may take some time before
the reading becomes stable for the final value.
¡On insulation resistance ranges, DC voltage is supplied through the earth lead
and the line probe lead, with the earth lead having positive polarity.
The earth lead should be connected to the earth conductor in the circuit under
test. Such connection is known to be more suitable for insulation testing since
insulation resistance values measured with the positive side connected to earth
are typically less than those taken through the reversed connection.
DANGER
¡When the test button or the remote control switch is pressed with the
function selector switch set to an insulation resistance range, never touch
the tips of the probes or the circuit under test, where a high voltage is
present in order to avoid possible shock hazard.
CAUTION
¡Do not perform insulation tests on an energized circuit to avoid possible
damage to the instrument or the circuit under test.
1. Check that the circuit under test is de-energized.
www.GlobalTestSupply.com

17
2. Check the maximum voltage that may be applied to the circuit under test. Set
the function selector switch to an appropriate insulation resistance range.
3. Connect the earth probe (alligator clip on black lead) to the earth terminal of the
circuit under test. If the circuit is not earthed, connect the earth probe to an
appropriate conductor.
4. Connect the line probe to the circuit under test and press the test button or the
remote control switch.
5. Take the reading on the scale for selected insulation resistance range.
6. Release the test button or the remote control switch. Leave the earth lead and
the line probe connected to the circuit under test. This will allow the Auto-
discharge function to dissipate charges built up by the circuit during insulation
measurement. Discharging can be checked by the AC voltage reading.
DANGER
¡To avoid possible electric shock hazard, never touch the circuit under test
until charges stored in the circuit are completely discharged.
¡Leave the earth and line probes connected to the circuit under test until
the meter pointer returns to the left end of the scale. Never touch the
circuit before discharging completes.
7. Set the range selector switch to the OFF position.
Caution: The circuit breaker for
the circuit under test
must be turned OFF.
