2. SAFETY REGULATIONS
2.13 Information on the high voltage
Attention high electrical voltage - mortal danger!
IN DEALING WITH HIGH VOLTAGE THERE IS DANGER TO LIFE!
When performing tests using the device you will be working with a high
voltage up to 5000 Volt AC or 6000 Volt DC. If the device is fitted with
options, significantly higher voltages can occur.
There is mortal danger
when working with high voltage!
Follow DIN EN 50191 (DIN VDE 0104). The EN standard regulates the
operation of test systems and test benches.
Attention high voltage:
The contact elements used for the HV and IS
test (test probes etc.) must be designed for the maximum voltage supplied
by the device.

2.14 Discharging test objects with internal capacitance
Attention discharge currents - mortal danger!! particularly in the case
of test objects with internal capacitance (capacitors).
Particularly during tests with
DC , test objects with internal capacitance
can store large amounts of charge . After disconnecting, this charge
may be dissipated via the operator‘s body (if the test object is touched in
the appropriate place).
If the test object is left connected to the tester after switching off the high
voltage, it will discharge automatically via the tester. If this discharging
is prevented (disconnection), potentially fatal discharge currents may be
produced.
Discharging via the device
After the end of the test (end of test time), the test object connected is auto-
matically discharged. For this purpose a discharge resistor is connected inter-
nally and the voltage across the resistor read (residual voltage measurement).
The discharging is undertaken using an internal resistor until a voltage of
3000 V is reached, the device then connects a 1 MOhm resistor in parallel.
If the voltage doesn‘t underrun a residual voltage of 60 V within - 10 s at DC
