Fluke 323 Clamp Meter- Common FAQs

  • Can you measure the amps correctly?

No, a clamp meter doesn’t measure the amps. You need to buy an AC line splitter kit to measure the amperage.

  • Is the hold feature last or maximum reading?

The Hold feature freezes the measurement. It is the last reading.

  • Does Fluke 323 measure AC or DC amps/voltage?

No, a clamp meter only measures current. So you can check the voltage or resistance directly through this clamp meter.

  • How to measure AC/DC voltage on the Fluke 323?

You just need test leads for AC or DC voltage and resistance measurement.

  • Can you measure a sine wave?

No, you need an oscilloscope device to measure it.

  • Can Fluke 323 measure the starter draw?

No, because it can’t measure high amperage.

  • What is the maximum frequency it can measure?

Maximum 65 Hz

  • Can Fluke 323 measure milliamps?

No, you cannot read this data.

  • Is Fluke’s 323 clamp meter made in the USA?

No, it is made in China.
