OPERATION
- Connect input terminal E To GND of test subject. Connect terminal L to test circuit. (Hang terminal L as much as possible. When testing cable, connect COM terminal to GND)
- PUSH the switch to “TEST” to turn ON the unit. LCD displays “1” (NOTE: When LCD displays change the batteries.)
- When press “TEST”, there is high voltage output at terminal “L” and “E”, (Press “TEST” again to stop data hold and return to normal status)
- If LCD display “1” after “TEST” there are two possibilities:
- The measured resistance may exceed the maximum range.
- The unit is connected to a open circuit.
- Note : When press “TEST”, there are high voltage output at “L” and “E”. DO NOT touch the subject resistance or disconnect test leads. The reading may flash but a stable reading or “1” will display.
- If no stable reading is shown, there are four possibilities:
- Connecting cable is too long.
- The humidity of the test environment is higher than standard.
- The outer layer of the subject resistance must connect to “COM”
- The subject resistance is not stable or in a critical state.
