Tips for buying a clamp meter
1: Detection object
According to different detection objects, AC current, DC current, or leakage current to select the model;
2: Detectable conductor specifications
With the testing site, there are different specifications from 21mm diameter to 53mm diameter.
3: Is it necessary to detect the true value?
A clamp ammeter using the average value method cannot correctly detect non-sinusoidal circuits such as motors and transformer circuits. To detect such circuits, a true RMS clamp ammeter should be used.
4: Other functions
Not only can detect the current, but also the detection function and recording output in one model.
Clamp ammeter is referred to as clamp meter. Its working part is mainly composed of an electromagnetic ammeter and a through-core current transformer. The core of the through-core current transformer is made into a movable opening and is clamped, hence the name clamp ammeter. It is a portable instrument that can directly measure the AC current of the circuit without disconnecting the circuit. It is very convenient to use in electrical maintenance and is widely used.
