Operating method:

Start-up, Shut down:

  • To start up the tester switch the power key to AC or DC gear. Once switched on the power key the LCD begin to display.
  • To shut down the tester switch the power key to OFF gear.
  • To reduce the battery consumption the leaker shut down automatically after starting up for 5 minutes.
  • LCD send the flick notice the leaker is going to shut down automatically after flickering for 30 seconds.
  • By pressing HOLD key when LCD is flickering the leaker will continue to work for 5 minutes.
  • If the tester power off automatically the gear should be power off first and then start-up the tester.

Calibration:

When measuring the current, choose AC or DC gear. 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.

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 again HOLD key 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 display Unit 1 data storage automatically and press again the HOLD key 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 return to 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.

Electrical Signs:

  Extremely dangerous. Operators should follow the safety rules. There would be dangers of electric shock to cause personal injuries or casualties.
