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 Ωwith 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 deection 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
kΩscale.
6. Disconnect the test leads.
Insulation Testing (MΩ)
Automatic circuit discharge is eective when the test button is released, and
decaying voltage is indicated by the scale needle until the circuit is
discharged.
1. Select
MΩwith 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 deection 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
MΩscale.
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.
Refer to Safety Warnings before using the instrument
MEASUREMENT SCALES
Using the Guard Terminal
For basic insulation tests and where there is little possibility of surface
leakage aecting the measurement, it is unnecessary to use the guard
terminal.
In cable testing, there may be surface leakage paths across the insulation
between the bare cable and the external sheathing due to the presence of
moisture or dirt. Where it is required to remove the eect of this leakage,
particularly at high testing voltages, a bare wire may be bound tightly around
the insulation and connected via the third test lead to the guard terminal ‘G’.
The guard terminal is at the same potential as the negative terminal. Since the
leakage resistance is eectively in parallel with the resistance to be
measured, the use of the guard causes the current owing through surface
leakage to be diverted from the measuring circuit. The instrument therefore
reads the leakage of the insulator, ignoring leakage across its surface.
