4.5.3 Test Sequence
!
Attention!
Make sure that all points of access to the danger zone
have been secured
before testing is started , and that no
persons remain within the danger zone when the system
is made
ready for activation .
➭
Turn the key switch to the “I” position.
The test instrument is switch to the stand-by mode.
The green signal lamps are illuminated.
➭
Check the test parameters.
➭
Press the START key.

Danger: High-Voltage!
Touch neither the test probes nor the device under test
during the voltage test!
A
life endangering high-voltage of up to 5 kV is present at
the high-voltage module test probes!
➭
Position the high-voltage pistol in proximity to the device under
test.
➭
Pull both triggers, but only pull the trigger at the high-voltage
pistol with switch to its initial limit stop.
The test probes are exposed.
➭
Establish contact with the test circuit.
➭
Pull the trigger at the high-voltage pistol with switch to its final
limit stop.
High voltage is now switched to the test probes.
Testing continues until the selected rise time and the test duration
have elapsed.
An acoustic signal is generated by an internal buzzer for the
duration of the test (application of high voltage including rise and
decline).
➭
For subsequent testing of neighboring circuits, release the
trigger until it reaches its initial limit stop, establish contact with
the next test circuit and pull the trigger to its final limit stop.
Testing is started again.
