    Q1: What is a clamp meter?
    A1: 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?
    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: How to measure AC current with a clamp meter?

    A clamp-on meter is a special digital multimeter with a clamp-on head for measuring current. So when using the clamp meter head to measure AC current, make sure the test probe is removed from the clamp meter. Then follow the steps below step by step.

    • Turn the measurement function selection dial to AC current.
    • Press the trigger to open the clamp, extend the wire to be measured into the center of the clamp, and then slowly release the trigger until the clamp is completely closed.
    • Read the measurement result from the LCD.
