Establish the connection between the high-voltage terminal and the test objects conductor
which will be tested. To this end, plug high-voltage plug into high-voltage connection socket
and screw it in place.
Connect the connecting cable, which is permanently fitted to the operating unit, to the high-
voltage unit (connection socket
). Connect operating unit to the power supply.
If the device is powered by Mains Voltage from a grounded Mains socket (the yellow
control light lights on), there is no need of additional grounding by the green/yellow
protection ground cable. That’s important to avoid ground loops.
