Test time
The test time is the duration of an individual test.
By default, manual tests run without a time limit (test time= 0seconds). The test person must
decide on the basis of the currently displayed values whether the test can be completed or not.
By default, the test times of the automatic test procedures are set to 5seconds each. If the test
time for automatic testing is set to ‘infinite’ (0), the “Stop” button must be tapped to complete the
test. In case of another setting, the test will be completed automatically after the test time has
elapsed.
Polarity reversal of the testing voltage
For manual individual tests that require a polarity reversal of the testing voltage, you can carry
out the polarity reversal by tapping the buttons "L<->N" and "N<->L”.
Visual inspection
The device provides three different types of visual inspections:
• Standard visual inspection
• Advanced visual inspection
• Customer-specific visual inspection
A test sample may only be electrically tested if no serious defects have been detected during
the visual inspection.
Standard visual inspection:
The standard visual inspection includes the following questions, the result of which can be
evaluated with "OK" or "Error":
• “Is the Type plate OK and is the test sample provided withall warnings?”
• “Carry out a visual inspection of housing, cables and connectors.”
Advanced visual inspection:
The advanced visual inspection includes 18questions that can be shown or hidden as needed
using the ON/OFFsliders before the visual inspection begins. The visual inspection is started
manually by tapping the "Start visual inspection" button. The result of the visual inspection can
be evaluated for all with “AllOK", or for each question with "OK", "F" for error or “N.A." for not
available.
Customer-specific visual inspection:
The customer-specific visual inspection offers you the possibility to formulate customer-specific
questions and checks. The customer-specific visual inspection is structured like the extended
visual inspection.
