INSTRUMENT LAYOUT, DISPLAY INFORMATION & SYMBOLS

LCD display area: displaying the measured data and functional symbols.
Functional key area: selecting basic functions. Rotary switch: selecting the measurement function/

Measurement port area:

1. Positive terminal for continuity /resistance measurements
2. Negative terminal for continuity /resistance measurements.
3. Positive terminal for AC/DC voltage measurements and insulation resistance measurements.
4. Negative terminal for AC/DC voltage measurement and insulation resistance measurement.

1. SAVE/CLEAR
   Short press SAVE / CLEAR button to save the current measurement data. Press RECALL to enter measurement recall interface, Press SAVE/CLEAR button for 3seconds, this will delete all saved data “CLR” will be displayed once completed.
   

2. RECALL
   With a short press on the button, the previously saved measured values are retrieved, to exit the function press the recall button.

3. HOLD/
   With a short press on the button, enables the hold measurement mode, press the hold button to disable.
   Press & hold the button for 3 seconds to activate the backlight, either switch the instrument off or press & hold the button to deactivate the backlight.

4. COMP
   The button is used to define the pass/fail comparison value for insulation measurement. “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, 50M, 100M, 200M, 300M, 400M, 500M, 1 G, 2G, 3G, 4G, 5G and 1 0G.

5. Pl/DAR
   The button is used to configure the testing instrument to conduct insulation polarization index or absorption ratio test. 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 1 min: 30s; with the third short press, the screen displays Pl (polarization index) and currently the time ratio (TIME2:TIME1) is set as 1 0min: 60s; and with the fourth short press, the Pl/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. LOCK/TIME
   Is a multiplex button. With a short press on the button, you can set the test time mode. press the test button starts the timer until the test button is pressed again or the test will automatically stop the test after 60 seconds. Press & hold the TIMER/ LOCK button to activate & deactivate the test lock function.
   

7. TEST
   Activates Insulation & continuity/ resistance measurements.

8. Up and down regulation
   Function 1: used to set the insulation measurement voltage output.
   Function 2: used to save the up and down retrieval while recalling the measured data.
