  2. AC indication
  3. Negative polarity indication
  4. Low battery symbol
  5. Data hold indication
  6. Stored data code
  7. Unit of current indication
  8. Value of current

 Operation

1.    Start-up, Shutdown

  1. Press key to start up, LCD display will be turned on
  2. Press the key again to shut down the meter
  3. After starting up, if the Clamp meter is left idle for 5 minutes, the LCD displays a message that the meter will shut down automatically. After flickering for 30s, it will shut down formally to reduce battery consumption
  4. In case  key is pressed when the LCD was flickering, the meter will continue to work for 5 minutes
  5. In case the LCD display is very low, charge the battery

2.    AC/DC Measurement Switch

The meter defaults to DC measurement after boot up. Press  to switch to AC/DC function. LCD will display DC or AC to corresponding switch function.

3.    DC Calibration

Before measuring DC current, press DCA ZERO key to reduce the residual magnetism to Zero and then conduct the measurement. Rational usage of this Adjust Zero function will make the results more accurate. For example, after boot, before measurement, we can take the jaw close to the DC current wire. LCD will show an inductive current. Press DCA ZERO to calibrate, which deducts the inductive value. This is shown below:

4.    Current Measurement

High voltage, extremely dangerous! Operators shall strictly observe safety rules; otherwise there would be risk of electric shock which causes personal injuries or casualties.
  Dangerous!Please don’t use it to measure current higher than 300 A; otherwise there would be risk of electric shock which causes personal injuries or equipment damages.
  1. Power on
  2. Press  for DC or AC measurement. Adjust Zero before measuring the DC current.
  3. Release the toroid lever to open input toroid and clamp measured conductors. Be careful to see that the two input toroid must be totally closed and the measuring wire is passing through the centre of the jaw
  4. Read LCD display data. In case OL am symbol was displayed, it means that the current of measured line is beyond the maximum limit of this meter; In this case, please choose meter with much higher range limit

  Attention! For your safety, when measuring heavy current, after confirmation of the completion of correct operating test, please move the meter away from measured conductor
In locations where the data is difficult to be read, please use the data holding function. If [DH] symbol is displayed, please discharge data holding state first, and then do the test

5.    Peak Holding

Press HOLD key continuously in the course of measurement (More than 3 seconds), the meter will capture current peak values of lines in this period of time. After releasing the key, it will then return to the measuring state.

6.    Hold, Storage and Access Reading

  1. Press key for a short time in the course of measurement (less than 3 seconds), symbol will display. The leaker will hold current measuring data and automatically store in the memory with a unit ID. Press key again to release the hold state and the leaker will continue to measure data. In case stored data reached to 60 groups, press key again and the “” symbol will display, which means storage memory is full; press key to cancel
  2. Press + keys to enter into data access mode and display Unit 1 storage data automatically. Then press key again to turn to the page of stored data. will display when there is no data stored in the memory. Press key to exit data access mode
  3. After entering into data access mode, press key for more than 3 seconds to clean up all stored data. When the leaker displays “” symbol, it means that it has finished clean-up process, and then returns to the measuring state automatically.

7.    Data Upload

Connect the RS-232 or USB communication wire of the Tester. Switch on the Tester and run the monitoring software. If the software displays that the interface is open and the connection is successful, then the stored historical data can be read, uploaded and preserved.

Monitoring software has the function of online real-time monitoring and historical inquiry, dynamic display with the maximum, minimum and average value indication, alarm value settings and indicator, function of historical data access, reading, storage, print and other functions.

How to Change Battery

  Warning! It is dangerous to carry out test when the battery cover plate is not on its position.
Please pay attention to the polarity of battery to avoid damaging the leaker
Chang the low battery in time
If you expect not to use the meter for a long time, please get off the battery to storage
  1. ” symbol means the battery is low and need to be replaced
  2. Press key to shut down the meter. Before opening the battery cover, please confirm the meter is in off position and then replace
  3. With qualified new battery, special attention shall be paid to the polarity of battery. Cover the battery cover plate
