4.3.3 Insulation Resistance Test Mode
Figure 4-14 IR Test Setup
Setting item
Range
Default
Explanation
MeasVolt
0.050~5.000kV,
0 —CLOSE
CLOSE
(no test)
Set the voltage required for the insulation
resistance test.
Must be changed from CLOSE to
a voltage for the step to become valid.
Lowlimit
0.1M~50GΩ
1.000MΩ Set the insulation resistance low limit.
Hi Limit
Low limit~50GΩ,
0 —CLOSE
CLOSE
Set the high limit of the insulation resistance,
which is greater than the low limit of the
insulation resistance or Close.
Ramp Time
0.1~999.0s,
0 —CLOSE
CLOSE
Set the time required to rise to the set voltage.
If the ramp time is CLOSE, the voltage ramp is
completed during the first cycle of the test.
MeasTime
0.3~999.0s
0 — Continue
3.0s
Set the measurement time for the insulation
resistance test.
0 indicates that the test is continued until STOP
key is pressed.
Fall Time
0.1~999.0s,
0 —CLOSE
CLOSE
The ramp time it takes to drop from the set
voltage to low voltage.
CLOSE means that when the test time is over, the
voltage output is cut off directly. (The DUT may
still be charged).
MeasRang
Auto,
10mA,
3mA,
300uA,
30uA, 3uA, 300nA
Auto
Set the current measurement range of the
insulation resistance. When in Auto, it will
automatically switch to the corresponding range
according to the change of the test value. The
fixed range is fixed to the selected range.
