Use A Digital Clamp Meter

Using a digital clamp meter is an uncomplicated and safe way to measure current in a circuit. Unlike regular meters, the clamp type does not put the meter into the circuit, but measures the field induced by a current passing through the clamp. It is suitable for moderate (<480V) voltage and current applications.


Instructions


Measuring Current with a Digital Clamp Meter


1. Remove power from the circuit, if possible. Working on a hot circuit involves extra risk to the user and all equipment involved.


2. Isolate a wire carrying the current you wish to measure.


3. Open the clamp portion of the meter and then close it around the wire (and only that wire) you wish to measure current passing through.


4. Set the clamp meter to read the current type (AC or DC) and the expected range in milliamps or amps. If you don't know the range, guess high, and dial down as needed.


5. Return power to the circuit and read the digital display, writing the value down to avoid repeating the process. If the reading fluctuates, give it a minute to settle down.


6. Remove power from the circuit. Then remove the clamp meter.
