Figure 4.3.3 IR setup interface
Instruction:
VOLT:
0.050~1.000kV
Voltage value of IR test
UPPER:
0.1M~50.00G
High limit value of IR
OFF
No judge for high limit value of IR
LOWR:
0.1M~50.00G
Low limit value of IR, it must be smaller
than the upper limit value.
OFF
No judge for low limit value of IR
TIME:
0.1~999.9S
Test time of IR.
OFF
No limit for testing time
RISE:
0.1~999.9S
Rise time of insulation voltage.
OFF
Default=0.1S, time conformity with
testing time
FALL:
0.1~999.9S
Fall time of insulation voltage.
OFF
Cut off voltage output after testing. (the
DUT may be electrically charged)
RANG:
AUTO
Auto-range mode. The range changes
with the test value.
TH9320
2uA, 20uA, 200uA,
2mA, 10mA
Fixed range mode. I=U/R can be used to
estimate the accelerated the test speed and
the increased test accuracy according to
the range.
TH9310
1uA, 10uA, 100uA,
1mA, 5mA
NOTE:
When RANG is set as AUTO, the min. range switch time is 0.6s. Please pay attention to it!
Current acquisition lags 20ms behind the voltage acquisition, so the displayed resistance
value in rise time is smaller than the normal and the resistance value in fall time is larger than the normal
value. Hereby is instruction for your reference.
