Start Measurement

If you have changed the transformer ratio at the test instrument, a

popup window appears prompting you to enter this new setting

to the connected current clamp sensor as well.

i: Prompt regarding

currently selected

transformer

ratio at the

tester

Clamp

: Selective earth resistance measured with clamp

Probe

: Earth resistance measured with probe, comparative

value

Note

The following diagram appears if the

2-pole adapter is connected

incorrectly.
