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: The difference between a clamp meter and a digital multimeter
In the industrial production process, some low-voltage equipment or circuits that are running need to know the current situation at any time, but the equipment must run continuously. In order not to affect the production or bring unnecessary losses, it is impossible to connect the digital multimeter to the equipment in series after power failure and then measure the current in the circuit. Therefore, in order to measure the current without cutting the circuit, a clamp meter was developed based on the basic digital multimeter. Although it is not as accurate as a multimeter, it provides a valid reference standard for maintenance personnel. Moreover, it is easy and convenient to operate. Therefore, the difference between a clamp meter and a digital multimeter is the way to measure current. Clamp meter can directly measure the current in the line, just press the trigger to open the jaws, and put the single line to be measured in the middle of the jaws without disconnecting the power line. And ordinary digital multimeter to measure the current, the multimeter's black and red pointer in series must be connected in series with the power line.
