Insulation Tests

Test Description

This test is used to verify that adequate insulation exists between the
mains supply pins and earth.

During the insulation test, a 250V or 500V DC voltage is applied
between the earth pin and both the live and neutral pins of the
appliance mains supply plug. The Tester displays the resistance
measured and allows the user to confirm sufficient insulation exists.

For Class 2 appliances, the Earth Continuity Test is used for an earth
return lead.

For appliances which incorporate over-voltage protection, and hence
produce a false failure condition when 500v insulation tests are used,
a 250V test voltage is provided to allow a reading to be taken without
the protection devices generating a false failure.

User Selectable Settings

Each press of the SELECT button will allow you to cycle through the
user selectable settings; test duration, test voltage and test limit. The
currently selected setting will be flashing.

Test Duration
With the test duration flashing, use the cursor keys to step through
the test duration settings. A test duration can be set from 2s to 60s in
1s steps or a continuous measurement indicated by two dashes (--).

Press the SELECT button to change to another setting or press the
START/STOP button to perform the test if the other settings are
acceptable.

Test Voltage
With the secondary display flashing and indicating voltage (v
displayed), use the cursor keys to step through the test voltage
options. A 250V or 500V test voltage can be set.

Test Limit
With the secondary display flashing and indicating resistance (M

Ω

displayed), use the cursor keys to step through the test limits
available and stop with the appropriate limit displayed.
