Measurement
1) Power on
2) Switch AC/DC key to choose the kind of measurement.
3) Adjust zero
4) Release the toroid lever to open clamp mouth and clamp measured conductors.
5) Read LCD display data. In case OL A symbol was displayed, it means that current of measured
line is beyond the maximum limit of this leaker; with this case, please choose leaker with much
higher range limit.
Clamp positive wire and negative wire together is to measure leakage current of DC
circuit. (Note: 2 wires)
Clamp live wire and null line together is to measure AC leakage current. (Note: 2 wires)
Clamp earth wire is to measure grounding line leakage current. (Note: single wire)
Clamp main wire is to measure the current. (Note: single wire)
4. Hold, Storage, Access Reading and Deleting
1
）
Pressing HOLD key for a short time in the course of measurement (less than 3 seconds), DH
symbol will display, the leaker will hold current measuring data and automatically stored in the
memory with a code; press HOLD key again to release the hold state, and the leaker continues
its measuring; in case stored data reached to 60 groups, press HOLD key again, the
“
FULL
”
symbol will display, which means storage memory is full; press HOLD key to cancel
“
FULL
”
flickering and return to measuring mode.

）
Long press HOLD key to enter into data access mode and display Unit 1 storage data
automatically; and then press HOLD key again to turn the page of stored data; null will display
when there is no data in stored in the memory, power off the meter to exit data access mode.

）
After entering into data access mode, press HOLD key for more than 3 seconds will clean up all
stored data; when the leaker displaying
“
dEL
”
symbol, it means that it has finished clean up
process, and then return to measuring state automatically.
5. Data Upload
Make good connection of computer and the tester with RS232 communication wire, switch on the
tester and run monitoring software. If the connection is successful, then it can read the stored historical
data, upload to company, preserve and print.
