OPERATION
Default Voltage measurement
The
210170
will act as a default voltmeter (0 to 600 V a.c.) with any of the
Insulation test positions selected. The ‘Test’ push must not be pressed when
making a voltage test. Note:- The
210170
is internally fuse protected to 500
V. For fuse protection with supplies above 500 V, use Fuse Probe Kit FPK5.
1.
Select any Insulation test position with the rotary selector switch.
2.
Carefully connect the test leads to the circuit under test. Do not press the
‘Test’ push.
3.
Read the voltage measurement from the voltmeter scale.
4.
Carefully disconnect the test leads.
Low Resistance measurement (
Ω
)
1.
Select
Ω
with the rotary selector switch.
2.
Ensure that all test leads are clean and in good condition, and connect
them to the isolated circuit under test.
3.
Any pointer deflection indicates a live circuit, and testing should be
aborted.
4.
Press the ‘Test’ push, and keep it pressed while turning the generator
handle.
5.
Read the measurement from the k
Ω
scale.
6.
Disconnect the test leads.
Insulation Testing (M
Ω
)
Automatic circuit discharge is effective when the test button is released, and
decaying voltage is indicated by the scale needle until the circuit is
discharged.
1.
Select M
Ω
with the rotary selector switch.
2.
Ensure that all test leads are clean and in good condition, and connect
them to the isolated circuit under test.
3.
Any pointer deflection indicates a live circuit, and testing should be
aborted.
4.
Press the ‘Test’ button, and keep it pressed while turning the generator
handle.
5.
Read the measurement from the M
Ω
scale.
6.
Release the ‘Test’ push and monitor any scale needle movement to
confirm when any discharging voltage decays to zero.
7.
When the circuit has discharged, disconnect the test leads.
