Number Measurement Function
1
Starts the selected test. The TEST key is surrounded by a “touch pad”. The touch
pad measures the potential between the operator and the tester’s PE terminal.
If you exceed a 100 V threshold, the
W symbol above the touch pad is illuminated.
2 Set RCD variable trip current.
3 Illuminates when > 100 V is detected on the touch pad.
4 Zero the test lead resistance offset.
5 Turns the backlight on and off.
6
Turns the tester on and off. The tester will also shut off automatically if there is
no activity for 10 minutes.
