    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 use a clamp meter to measure AC/DC voltages?
    It is important to note that there is a risk of electric shock. When measuring high voltages, extreme care should be taken to avoid electric shock. Do not attempt to use this clamp meter on voltages higher than DC/AC 600V rms.

    • Press the measurement function selection key to DC or AC voltage measurement.
    • Connect the black lead to the COM probe socket and the red lead to the INPUT probe socket.
    • Read the measured value from the LCD. The polarity display will show the polarity of the terminal to which the red test is connected.

    Clamp Design for Non-Invasive Measurements
    The clamp design enables non-invasive current measurements by clamping around the conductor, eliminating the need for direct contact. This is a crucial safety feature, minimizing the risk of electric shock and streamlining the measurement process.

    Reliable digital clamp meter provides plenty of light for my work
    The AC digital clamp meter is very accurate and has a wide range of measurement capabilities. The clamp meter's built-in torch is also ideal for working in darker environments.
