PAT400 Series

22

The insulation test probe is connected to all exposed
metal parts to ensure electrical separation from
earth.

3.4.1

Test lead resistance null

The resistance of the Bond lead can be “nulled” to remove the lead resistance from the measured resistance. This is important when
testing very low resistances where the test limit is set to 0.1ohms.
Also, the resistance of an extension lead (IEC or Power cord) can be nulled, if the lead is longer than the Red test lead supplied with the
PAT.

Symbols used:

z

Test lead null is set

z

Extension lead adaptor null is set, see section 3.4.2

z

Both Test lead and extension lead adaptor null are set

To null the test lead resistance of a bond lead:

1)

From the HOME screen, use the RIGHT arrow key to select the SETUP tab.

2)

Press the NULL

z

Hotkey. The Lead Null screen will appear as below:

(If a lead null value is already set the lead null symbol

z

will be displayed)
