What is a clamp meter?

Unlike traditional multimeters, which require you to break the circuit, clamp meters let you measure current by simply clamping around a single wire. This makes them especially useful for troubleshooting and maintenance in live electrical systems, such as in industrial machinery, HVAC units, and electrical panels.

How do I choose a load current clamp meter?

Choose an AC load current clamp meter for ordinary measurement applications, or a leakage current clamp meter if you need to measure leakage currents caused by insulation defects or current flowing in a ground wire for electrical equipment.

Do you need a clamp meter?

For example, in order to measure a battery used in an automobile or uninterruptible power supply (UPS), or a photovoltaic cell, you’ll need a clamp meter that can measure DC current.

How do you measure a clamp meter?

Most clamp meters have a dial that allows you to select what you’re measuring: A (Amps): To measure current. V (Volts): To measure voltage. Ω (Ohms): To measure resistance. Some meters may also have additional features such as continuity testing or diode testing. Turn the dial to the appropriate setting based on what you want to measure.

Where should a clamp meter be placed?

Position the wire in the center of the clamp for maximum measurement accuracy. Clamp meters designed to measure load currents can only be clamped around one wire. Be careful not to clamp the instrument around multiple wires at the same time as doing so will prevent proper measurement.

Can a clamp meter be inserted into the input socket?

When measuring current, the test lead can not be inserted into the input socket. When you hold the clamp meter to measure, you should keep the fingers behind protection ring of meter body. Before on-line resistance measurement, you should turn off the power for all circuits and discharge all capacitors.
