Figure 4.3.3 IR setting interface
IR test parameters are as follows:
VOLT
:
0.050
~
1.000kV
Insulation test voltage value
UPPER
:
0.1M
~
10.00G
Upper limit of IR
OFF
Do not judge the UPPER limit of the insulation
resistance
LOWR
:
0.01M
~
10.0G
Lower limit of IR, should be less than Upper limit
TIME
:
0.1
~
999.9S
IR test time
OFF
Unlimited test time
RISE
:
0.1
~
999.9S
Insulation voltage rise time
OFF
Default=0.1S, Integration with test time
FALL
:
0.1
~
999.9S
Insulation voltage fall time
OFF
Directly cut off voltage output at the end of the
test(The DUT may be charged)
RANG
:
AUTO
Automatic range mode; Improve test accuracy
ST9320 series
2uA, 20uA, 200uA, 2mA, 10mA
Fixed range mode: can use I=U/R to estimate the
range to speed up testing
ST9010 series
1uA, 10uA, 100uA, 1mA, 5mA
Fixed range mode: can use I=U/R to estimate the
range to speed up testing
Note:
1.
The instrument judges the upper and lower limits at the end of the test. The current short
limit is keeping working!
2.
When in auto range, due to range switching, the minimum test time is 0.6S.
3.
Due to current and voltage acquisition timing effects, voltage rise time and voltage fall time
show significant deviations in resistance values, hereby explain for your reference.
