4. Judgement of test result
(1) Judgement system
High limit
Analog comparator.( For short-circuit
detection, set value internally fixed. )
High and low limit
Digital comparator.
(2) Adjustable range
High limit AC:0.1~110.0mA (low limit + 1 digit or more)
DC:0.1~11.0mA (low limit + 1 digit or more)
Resolution 0.1mA (0.1~110.0mA, for DC up to 11.0mA)
Low limit
AC:0.0~109.0mA (high limit – 1 digit or less)
DC:0.0~10.9mA (high limit – 1 digit or less)
Resolution 0.1mA (0.0~109.0mA, for DC up to 10.9mA)
Note1
: Low limit setting can be ON/OFF
Note2
: High and low limit value for the AC withstanding voltage test
and the same for the DC withstanding voltage test are
memorized as independent item with each other.
(3) Judgement condition
High limit value
＞
Leak current
＞
Low limit value … GOOD
High limit value
≦
Leak current ………………………. HIGH NG
Low limit value
≧
Leak current ………………………. LOW NG
Note:
Output time of GOOD judgement can be switched to
continuous or 0.2s.
For the AC withstanding voltage testers, the leak current due to the
capacity distribution in the high voltage cable, jig and so on can
cause the judgement error.
Please determine the judgement criterion value, taking this leak
current into account.
The following values are the referential values on condition that the
wiring is made, keeping the distance between HIGH voltage side
cable (red) and LOW voltage side cable(black) of the attached high
voltage cable (5880-25-020).
