Q1: What is a clamp meter?
Q1: A clamp meter is a device used to measure current conveniently and safely. It is very efficient to measure current without using test leads. To measure
current, all you have to do is place a wire in the jaws of the clamp meter. When current flows through a conductor, a magnetic field is created. The device helps to detect magnetic fields so that it can provide corresponding current readings, the sisco clamp meter can also be used as a multimeter.
Q2: How a clamp meter works?
A2: Clamp meters work on the principle of magnetic induction and measure alternating current without contact. Like every conductor, the current flowing
through the wire creates a magnetic field. Hall effect sensors detect the magnetic field produced by the current, which in turn creates a small voltage
across the sensor.
Q3: How often does a clamp meter need to be calibrated?
A3: A clamp meter typically needs to be calibrated annually to ensure it continues to measure within sisco's specifications.
Tips: Clamp meter NCV function
Set the functional range switch to the NCV position. At this time, the digital clamp meter displays 'NCV' and '----' symbols, and the top of the clamp meter is close to the mains phase line, power switch, and socket waiting for the object to be measured. When the detected voltage is greater than 110V (AC RMS), the meter will light up the corresponding signal strength indicator (high, medium, low) according to the detected signal strength, and the buzzer will alarm at different frequencies.
