Fluke 323 true-rms clamp meter

Fluke 323 clamp meter

Many HVAC technicians have a wide assortment of multimeters, but the Fluke 323 true-RMS clamp meter is a great general-purpose meter for problem-solving. This meter has been dropped from great heights and dragged into numerous crawl spaces. We had one that was covered in paint containers sprinkled for hours and we thought it counted.

The next day the meter was driven and has never failed to work correctly since. We bought the first meter for field work. And this is one that is still used today.

Of course, a multimeter is an essential element in your toolbar for almost any task. Being able to get an accurate text about a system’s electrical aspects helps you pinpoint problem areas. This helps to isolate where problems may occur. Where does the juice need to go? Is it a component that is bad, or the electricity so far? Are the wiring enough to handle the amperage?

These are all essential functions. This helps ensure that the system serves its purpose to provide people with comfort or to provide refrigeration. More importantly, it is also essential to make sure that the system is working safely – preventing equipment erosion, or worse – fire or explosion.

What Can It Do?

If you haven’t used a clamp meter yet, the idea is simple: two jaws open so you can place the device around a cable or any other area you want to measure and clamp together. This means that now the jaws are just around him, and reading can be taken. It is the safest and fastest method of measurement and provides a greater accuracy level than a few other instruments.

Fluke is a manufacturer that provides clamp meters and other equipment. So you have the knowledge and quality advantage and lots of satisfied users who testify to the performance and value of this little tool. The general response is a precise and easy-to-use device that does the job designed to do this, including the entire board’s accurate reading.

The Fluke 323 has received a very favorable review indeed, with users pointing to its effectiveness in measuring AC currents with a high level of accuracy – be aware that this tool will not measure DC currents.

It is also noteworthy that this model brings the test lead; users and manufacturers strongly advise for the most accurate reading of voltage and resistance. The clamp itself must be used for reading. Other comments on the note raise concerns about digital LCD readouts, which are clear enough and large enough to give you the information you need. The Fluke 323 is not backlit, which can be a problem in confined or awkward spaces, but some models provide a backlit readout for very little extra expense.

Key Features

  • True RMS Detection
  • Soft Case
  • Audible Continuity Sensor
  • Meets CAT III and IV requirements

The Fluke 323 In-depth Review

The Fluke 323 is known for its great features and strong build. It consists of a true RMS detection meter and meets electrical safety standards. Because of this, the multimeter is capable of measuring voltage, continuity and amperage. It also provides accurate text when observing both linear and linear loads regardless of wavelength size. Also, it consists of a melody continuity sensor and a low battery sensor to make it more audio-friendly. This helps the user to quickly detect continuity, making it easier to save accurate measurements. When saving battery power for later use.

Packages and Accessories

If you are also interested in regular multimeters, you may want to check out Fluke’s combo pack that includes 323 clamp meters with 117 multimeters.

There are a number of products available to the right of the manufacturer that complement your Fluke 323 selection. They come in boxes of 6 or 50.

You can also buy electric lead with a clamp meter. The TL223 pack contains 3 test leads and 3 alligator clips.


The Fluke 323 True-RMS Clamp Meter measures blood pressure, voltage and continuity. The MPV meter is one of the most powerful tools in the arsenal of HVAC technicians for problem-solving. This may indicate whether a component has power on. It also helps to show how much the motor or compressor is running before you snap your finger twice.

This clamp meter measures resistance up to 400 ACP AC current, A / C or D / C voltage up to 600 volts and up to 4 kHz. The resistance feature also includes an audible continuity indicator to test ohms at hard-to-access spots that make it difficult to see the display.

This meter is running a lot for this. Let’s look at some of its strong points:

  • This tool is a true-RMS meter. True-RMS meters are an industry standard due to their ability to read distorted waveforms due to nonlinear loads such as variable speed motors.
  • Ahold button to record the latest readings and an audible indicator for continuity make this meter easy to use in situations where it may not be possible to look directly at the display.
  • Clamp meters are easy to hang with the tool, allowing both hands to be free while solving problems.
  • It’s a name-brand meter at an affordable price – and they toss in a soft carrying case for boots.


  • This meter is not equipped with a backlight for easy visibility in low light conditions. And we all know that we are often in this situation.

Benefits of using the Fluke 323 Clamp Meter
