3 OPERATING INSTRUCTION
3.1 MEASURING CURRENT
1. Set the rotary switch at desired A
～
range position. Press the trigger to open the
transformer jaws and clamp onto one conductor only( Fig1 ), The transformer jaws
pick up the AC current flowing through the conductor.
2. When only the figure
“
1
”
displayed, it indicates overrange situation and the
higher range has to be selected.

3.2 INSULATION TEST
( Option 500V insulation tester unit )
1. Connect the insulation tester unit V

EXT.
2. Set the rotary switch of clamp meter at 2000M
Ω
position.
3. Set the insulation tester unit range switch to the 2000M
Ω
position.
4. Use the insulation tester unit of the test leads connect its L
、
E input connect to
being tested installation's. (Test installation's must be power OFF.)
5. Set the insulation tester power switch to the ON position.
6. Depress the PUSH 500V push-push switch, the 500V on red LED lamp will light.
Clamp meter display reading is the insulation resistance value. If the reading is below
19M
Ω
, change clamp meter and insulation tester unit to 20M
Ω
range, can be
increase the accuracy.
7. If the insulation tester unit is not use, the power switch must shift to power OFF
position, and the test leads must leave the E.L input connect. That can be increase
battery life and prevent electrical shock hazard.
