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.

• Loop input select (L-N, L-PE).
• Voltage input select (L-N, L-PE, N-PE).
• Insulation test: (L-N, L-PE, N-PE)
• RCD current rating (10, 30, 100, 300, 500, 1000 mA or VAR).
8
RCD Current multiplier (x1/2, x1, x5, AUTO).
