4.3 Test Result
Only in the measurement display interface can start high voltage to measure DUT, its test parameters must be
set in the measurement interface.
Figure 4-4 Test is Qualified
1)
After the test is boot-up, two big characters displays on the middle of the screen is the real-time test data.
The upper part is output voltage of high voltage, unit of withstand voltage is kV.
The lower part is measured current value of the test low-end or insulation resistance value of DUT.
2)
The middle area at the bottom of the screen is displays the test status and judgement result.
The right side at the bottom of the screen is displays the left time of high voltage test. If user select the
continuous test, then it will display the test time not greater than 999.9s.
3)
Judgement of test result
a)
For the withstand voltage test, the test result of the upper/lower limit of striking current can be judged at
any time.
b)
For the insulation resistance test, it will judge the result when the test time is near to close.
4)
Description table of failed test and abnormal protection
Judgement Result
Description
Over the upper limit
It indicates the measured value is greater than the upper limit.
Over the lower limit
It indicates the measured value is less than the lower limit.
Short-circuit
The output current of the instrument is greater than the setting current limit
of the internal, which is unalterable.
Electric arc
When testing AC/DC withstand voltage, the current arc is over the upper
limit of electric arc.
Groud failed
Groud is break off and failed.
the lower limit of charge
When testing DC withstand voltage/insulation resistance, the current is
lower than the setting minimum charge current.
Overvoltage
Output voltage is greater than the setting output voltage.
