5. Polarization index or insulation absorption ratio (see figure 7)
The wiring measurement method is quite similar to the insulation resistance measurement, just set it as
polarization index or absorption ratio; With a short press on the button,the screen displays DAR (absorption
ratio), time ratio (TIME2:TIME1) is simultaneously set as 1min: 15s;with the second short press, the time ratio
(TIME2:TIME1) for insulation polarization index is set as 1min: 30s; with the third short press, the screen
displays PI(polarization index) and currently the time ratio (TIME2:TIME1) is set as 1Omin: 60s; and with the
fourth short press,the PI/DAR (polarization index/ absorption ratio) test function is canceled.The test can be
conducted by pressing the test button after selecting a required time ratio.
6. Use of comparison (See figure 7)
The wiring measurement method is quite similar to the insulation resistance measurement, just need to set
it as the comparison function. “PASS” will be displayed when the measured insulation value is larger
than the set value, and “NG” will be displayed when the former value is less than the later one; press the
button to select the required comparison value, such as 100K, 200K,300K,400K,500K 1M, 2M, 3M,4M,
5M,10M, 20M, 30M,40M, SOM, 100M, 200M, 300M 400M,SOOM,1G,2G,3G,4G,SG and 10G.
Comparison value.
7. Use of data storage function
1.Save the measured value:with a short press on “SAVE”, save the current measured value, meanwhile the
saved number on the display screen increases by one group,with a maximum of 99 groups;
2. Recall the measured value: enter the data recall mode by pressing “RECALL”,then view the saved data by
means of the “Up/Down” button.
3. Clear the saved measured data: press “RECALL”± to enter the data recall mode, after a long press on
“SAVE/CLEAR”about 3s,the screen would display’’CLR”:t, indicating all saved data being cleared.
8. Power gear
To power off, tum the rotary switch to “OFF”.
9. Automatic power-off function
There will be blanking display on the screen and the instrument enters micro-power consumption state if not
turning rotary switch of pressing the button within 3 min.If need to awake the instrument, just tum the rotary
switch to “OFF”± and then to another measurement gear.
