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?
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: True RMS Zero Input Characteristics of Clamp Meter

To test the measurement of a sine wave signal, the true RMS measurement method has less error than the traditional averaging response method. True RMS clamp meters accurately measure sine waves, but when the signal under test is not being input (AC voltage function selected, input shorted), the AC function may show a reading between 1 and 50. These deviated readings are normal. They do not affect the accuracy of the clamp meter in measuring AC over the specified measurement range. True RMS requires a certain level of input signal to make a measurement. Therefore, the AC voltage and current ranges are specified between 2% and 100% of the full range.
