Output voltage dureing the insulation resistance test.
The lower limit of
resistance~10.00
G，OFF
The upper limit of the insulation resistance alarm.
The lower limit of the insulation resistance alarm.
(0.1~999.9)s,
continuous test
Test time for delay judement of insulation resistance test.
Rated voltage to rising slowly based on this period.
Rated voltage to falling slowly based on this period.
Set current scale to auto or fixed scale.
If the current range sets to [Auto], the instrument will
automatically select the proper current scale.
If the current range sets to [Fixed], it is necessary to set a
value at the lower limit of the resistance to determine the
current scale, which aims to shorten the test time. It is the
best way for sorting test.
The setting of the minimum charge current.
It is used to detect the test wire or test fixture whether is
normal connected, to make sure the correctness of the test
result. Since the leakage current is usually quite small during
the insulation resistance test, so the lower limit of leakage
current is hard to be the judgement to determine the test
wire or test fixture is correctly connected.
Since DUT is actually with some capacitive, so it can use
charge current of DUT to detect the test wire or test fixture
is normal connected.
Use numeric keyboard to input the numerical value of
the minimum charge current by manual.
To automatically set the numerical value of the
minimum charge current, please connect the
instrument and DUT with test line or fixture, and make
sure that the parameters of output voltage and slow rise
time are completely consistent with the actual test
data.
Explaination
1) The judgement of the upper/lower limit of resistance is only enabled when the delay judgement time is end,
other time is to detect abnormal protection.
