
Display the selected test parameters.

Confirm parameters with [Enter] or cancel with
[Cancel] .
The green illuminated pushbutton [HV On] signals
readiness for connection.

Operate the button [HV On] . High voltage is
connected, the discharge switch is opened.

The red illuminated pushbutton [HV Off] illumi-
nates and signals „High voltage is on“. At the
same time, the green illuminated pushbutton ex-
tinguishes.

To set the test voltage, slowly turn the rotary en-
coder
<Select> clockwise (100 V steps). While
doing so, observe the rise of voltage and current
on the instruments.

The voltage can be read on both the analogue
instrument and on the display.

After the predetermined test voltage is reached,
select the current measuring range with the se-
lector switch. Now you can read the leakage cur-
rent of the test object on the ammeter.
When the maximum output current is exceeded
(10 mA), the overcurrent release trips. Tripping of
the overcurrent release indicates that the test ob-
ject is defective.
When the nominal test voltage of the device is ex-
ceeded (at 52.5 kV), the overvoltage release trips.
Overcurrent Trip!
