SAFETY WARNINGS

✱ Safety Warnings and Precautions must be read and understood

before the instrument is used. They must be observed during use.

✱ The circuit under test must be switched off, de - energized and

isolated

before Insulation or Continuity tests are made.

✱ Circuit connections must not be touched during a test.
✱ The test button must not be pressed while connecting the test

leads or while changing ranges. (May cause ‘

Live Circuit

Warning‘ to become inoperable).

✱ The ‘Test’ button must not be pressed when making a voltage test.
✱ The Default Voltmeter, ’Live Circuit Warning‘ and Automatic

discharge

are additional safety features and should not be

regarded as a substitute for normal safe working practice.

✱ The 210600 is protected for connection to Power distribution

systems up to 300 V

Line - Ground, and 500 V Line - Line for

Installation Category

III*.

✱ It is recommended that fused test leads are used when measuring

voltage on high energy systems.

✱ After insulation tests, capacitive circuits must be allowed to

discharge

before disconnecting the test leads.

✱ Test leads, prods and alligator clips must be in good order; clean,

and with no broken or cracked insulation.

✱ Replacement fuses must be of the correct size, type and rating.

PERSONS.

OPERATION

Live Circuit Warning

The live circuit warning indicator will illuminate if 60 V or more is detected at
the terminals. Testing should be aborted if lit.

Default Voltage measurement

The 210600 will act as a direct reading default voltmeter (0 to 600 V
a.c./d.c.) in the ‘Standby’ mode (when switched ‘On’, and any of the
Insulation test positions is selected). The ‘Test’ push must not be pressed
when making a voltage test. Note:- The 210600 is internally fuse protected
to 500 V. For fuse protection with supplies above 500 V, use Fuse Probe Kit
FPK5.

1. Turn the instrument ‘

On’ by pressing the ‘On‘/‘Off‘ switch-button once.

2. Select any Insulation test position with the rotary selector switch. ’

V’is

displayed.

3. Carefully connect the test leads to the circuit under test.

Do not press

the ‘Test’ push.

4. Read the voltage measurement directly from the display.

5. Carefully disconnect the test leads and turn the instrument ‘

Off‘ by

pressing the ‘On‘/‘Off‘ switch-button once.

Low Resistance measurement (kΩ)

1. Turn the instrument ‘On’ by pressing the ‘On /’Off ‘switch-button once.

2. Select

kΩ with the rotary selector switch.

3. Ensure that all test leads are clean and in good condition, and connect
them to the

isolated circuit under test.

4. Press the ‘

Test’ push and read the measurement directly from the

display.

5. Disconnect the test leads and turn the instrument ‘

Off‘ by pressing the

‘On‘/‘Off‘ switch-button once.

Insulation Testing (MΩ)

Automatic circuit discharge is effective when the ‘Test‘ push is released, and
decaying voltage is displayed until the circuit is discharged.

1. Turn the instrument ‘

On’ by pressing the ‘On‘/‘Off‘ switch-button once.

2. Ensure that all test leads are clean and in good condition, and connect
them to the

isolated circuit under test.

3. Select the required test voltage with the rotary selector switch.

4. Press the ‘

Test’ push and read the measurement directly from the

display. Overrange is indicated by ‘ ’.

5. Release the ‘

Test’ push and monitor any displayed voltage to confirm

when any discharging voltage decays to zero.

6. When the circuit has discharged, disconnect the test leads and turn the
instrument ‘

Off‘ by pressing the ‘On‘/‘Off‘ switch-button once.
