This multimeter DT266 Mainly for measuring DC and AC voltage, AC current, resistance and diode,with continuity buzzer, data hold and insulation test function. is Best device for home repair. It is a good assistant to test and troubleshoot faults that exist in electronic device.

As a measurement principle, clamp meters detect the magnetic field emitted by current flowing in a wire in order to measure the current value. Unlike instruments like multimeters, this design has the advantage of being able to measure current without requiring that the circuit under measurement be cut.

How to read a clamp meter:

Taking a reading

1. Use the rotary selector to set the clamp meter to measure current.
2. Make sure that the range of measurement is correct. ...
3. Open the jaws of the clamp meter and put them around the wire whose current is to be measured.
4. Note the reading on the display.
