Operating method:

Start-up, Shut down:

  • To start up the tester press the POWER Once switched on the power key the LCD begins to display.
  • To shut down the tester press the POWER
  • To reduce the battery consumption the leaker shuts down automatically after start up for 5 minutes.
  • LCD sends the flick notes the leaker is going to shut down automatically after flickering for 30 seconds.
  • By pressing POWER key when LCD is flickering the leaker will continue to work for 5 minutes.
  • If the LCD displays dark after starting up, it is due to low voltage battery and change the battery immediately.

AC/DC switch:

The default measuring of current is DC current after start up the instrument. Press this key to switch the AC and DC current.

Reset:

Adjust the residual magnetism to zero using ZERO key and then conduct the measurement. Adjusting the ZERO key function to zero gives the more accurate result. After booting the meter and before measuring the current keep the jaw close to the DC current wire as shown in figure LCD will show an inductive current because of electric field interference. Clear the residual magnetism after measuring enormous current.

Measurement:

  • Start up the meter. Choose the AC or DC key for the kind of measurement. Adjust the residual magnetism to zero.
  • Release the toroid lever to open the clamp mouth and clamp conductors.
  • Read the LCD data. In case if the display indicates “OL A “ symbol, the current of measured line is beyond the maximum limit of this leaker ,choose the leaker with much higher range limit.

Peak Holding:

Press the HOLD key continuously while measuring the current more than 3 seconds, the leaker captures the peak values of the current. Releasing the HOLD key returns to measuring state.

Hold, Storage, Access Reading and Deleting:

  • By pressing HOLD key for a short time during measurement i.e.) less than 3 seconds “DH” symbol will display, the leaker hold measuring the current and the measured data automatically stored in the memory with a code
  • By pressing the HOLD key again, release the hold state and the leaker continues its measuring.
  • In case the stored data reaches 60 groups press HOLD key again “FULL” symbol denotes to storage memory is full.
  • To enter into data access mode press HOLD key for long time. It displays Unit 1 data storage automatically and press the HOLD key again to turn the pages of stored data. “NULL” display denotes when there is no data stored in the memory. Power off the meter to exit data access mode.
  • To clean up the data, enter into data access mode by pressing HOLD key less than 3 seconds all stored data get cleaned up. When the meter displaying “dEL” symbol, it means it has finished clean-up process, and returns to the measuring state automatically.

Data Upload:

Ensure the connection of PC and the tester with RS-232 communication wire is connected. Switch on the meter and run the software. If the connection is successful it can read the stored historical data, upload the data, store it and print.

The monitoring software has following functions

  • Online real-time monitoring
  • Historical query
  • Dynamic display
  • MIN-AVG-MAX indication
  • Alarm setting and indication
  • Data reading
  • Saving and printing.
