Frequently Asked Questions

What is the purpose of a clamp meter?

A clamp meter comes in handy to measure currents in a circuit, and this is done without the need of disconnecting it.

The hinged jaw, which basically ‘clamps’ the testing object, carries out the task. A clamp meter is mainly useful in performing circuit analysis with no external impact on the current circuit.

How can you differentiate between a clamp meter and a multi-meter?

A clamp meter is a device for measuring current only. On the other hand, a multi-meter measures voltage along with certain current associated features. But the difference within these two has faded out due to the newer models that integrate similar features.

What is the role of a true RMS clamp meter?

True RMS clamp meter measures alternating currents, which feature a polarized recurrent flow. For this reason, measuring these with standard tools can be tricky.

For overcoming the problems, a true RMS clamp meter is preferred.

Final Words

Clamp meters are incredible devices that help you in mapping out electric connections without executing invasive procedures.

Remember, that you require sound understanding related to electrical metrics for putting these tools to good usage. Before you select this device, it is always more helpful to invest wisely and think for the long-term.

Hence, before purchasing, make sure of getting something, which satisfies the expectation you have for it. We hope that these reviews have proved useful in finding you the right model for resolving your electrical issues.
