When abnormal current is detected during withstanding voltage
test.(Becomes NG for high limit of leak current.)
D
When the time to retain start signal is less than 40ms.
E
When start signal turns OFF in momentary action, during W test.
F
When the overload condition is detected during the DC withstanding
voltage test.

When the abnormality is detected in the DC high voltage power
source circuit during the DC withstanding voltage test.

Solutions
:
A :
Turn OFF the power supply immediately. The
8526
main unit is may be faulty.
Consult us or the dealer.
B :
Interlock input is turned OFF. Review the connection and sequence, and correctly
connect the interlock input.
Press
STOP
switch
②
and make READY status.
C :
The error is given when the connection is ON/OFF and the memory number or the
test mode is changed during the test. Press
STOP
switch
②
and make READY
status, and check the connection or sequence.
D :
In case that the test sample is short-circuited or abnormal current flows, the
judgement for high leak current becomes NG.
In view of priority on safety, the
8526
is designed to firstly check whether the load
(test sample) is short-circuited or not, faster than the measurement.
Consequently, the measured voltage at this moment is the value in half-way of
response and is not correct value. Pay attention to it.
After checking the connection or sequence, or replacing the load (test sample) with
correct one, press
STOP
switch
②
and make READY status.
E :
Press
STOP
switch
②
and make
READY
status.
When the ON time is less than 40ms, the error is displayed.
Make an arrangement to secure the start sequence 40ms or more.
F :
Press
STOP
switch
②
and make
READY
status. Make a connection so that the
start signal can not be OFF during the test, or review the sequence.
G :
In case that the capacity of the test sample is big, un-discharged high voltage may
remain in it.
Turn the power supply OFF and sufficiently discharge the test sample
in a proper way.
H :
Press
STOP
switch
②
and make
READY
status.
In case that the 8526 main unit is heated up, cool it down, leaving it as it is for 10
minutes or more.
If the 8526 is not heated up, another possibility is that the supply voltage
abnormality drops. Check the power source.
I :
Press
STOP
switch
②
and make
READY
status, and turn OFF the power supply.
The 8526 might have been broken down. Consult us or our distributor.
