DC Earth Continuity Tests

Class 2 (unearthed) appliances

This test cannot be performed since no earth connection is present in
the appliance plug.

Test Description

This test is to ensure that the connection between the earth pin in the
mains plug of the appliance and the metal casing of the appliance is
satisfactory and of sufficiently low resistance.

The test current is applied between the earth pin of the mains supply
plug and the earth continuity test lead clip.

User Selectable Settings

Each press of the SELECT button will allow you to cycle through the
user selectable settings; test duration 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 (--).

When a fixed test duration is set, the time will be divided into two
equal periods. During the first period a test current of +200mA will be
applied. During the second period a test current of –200mA will be
applied.

If a continuous test duration is set then, the first press of the
START/STOP button will generate a +200mA test current
continuously. Pressing the START/STOP button again will stop the
test. Pressing the START/STOP button a third time will generate a –
200mA test current.

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.
