Fluke 323 vs 324 clamp meter comparison guide
Both the above reviewed clamp meters are best in terms of quality and accuracy. But still they have a lot of major differences. Let’s have a look at some of its major similarities and differences. In addition, both meters measure voltage differently. If you want to check DC voltage then you can also visit my list of 7 best DC clamp meters.
If I have to compare all the features of fluke 323 and 324 then there are many similarities, let's have a look.
Similarities in Fluke 323 and 324
- Both fluke 323 and 324 have true RMS functions, which let them measure non-linear loads.
- Fluke 324 comes with a digital display, as does fluke 323.
- You can measure resistance with both fluke 324 and 323.
- Their package contains the same cat-III standard test leads.
- Both clamp meters have the same cat rating which is cat-iii.
- Fluke 323 and 324 have the same jaw size. (30mm)
- Both fluke 323 and 324 can measure only AC current.
- You can measure current up to 400A in fluke clamp meters.
- AC voltage readings of both clamp meters are the same, up to 600V.
- In both fluke 323 and 324, the option to hold data is also enabled.
- Continuity detection is available in both clamp meters.
Differences in Fluke 323 and 324
- Unlike Fluke 323 which lacks auto-ranging functions, Fluke 324 has automatic ac/dc voltage detection functions.
- Both fluke 323 and 324 can measure only AC current.
- The min max function is also available in both true RMS clamp multimeters.
- Fluke 324 is capable of measuring capacitance.
- Although both clamp meters have the same display but backlight option is only available in fluke 324.
- When it comes to weight, Fluke 323 ( 200 grams) is a bit lighter than Fluke 324 (300 grams).

Conclusion
If you’re looking for a true rms clamp meter then both fluke meters are good enough. Because both true rms clamp meters can measure ac current, which is compulsory for commercial and residential electricians. The major advantage of fluke 324 over 323 is that it has a built-in thermometer device. Moreover, you can get temperature readings in both Celsius and Fahrenheit.
The major electrical measurements like DC voltage, true RMS AC voltage, and current readings can be measured with fluke 324 true RMS meter. If your budget is a bit lesser but you need reliable performance with accurate reading then Klein Cl800 and cl900 also offer the same features.
FAQs- Frequently Asked Questions
Can Fluke 323 measure DC current?
No, fluke 323 can not measure DC current. If you want to measure DC current, DC AC Voltages measurements and capacitance feature then there are many reliable true RMS meters available. I have also made a list of the best clamp meters for electricians.
Is a clamp meter better than a multimeter?
Clamp meters and multimeters both have their own applications. If you want to measure contact temperatures then you need a thermographic camera. But to measure temperatures you can choose any of them. I have made a detailed comparison of multimeters Vs Clamp meters.
How does a continuity checker work in multimeters?
In Clamp meters and multimeters the working principle is almost the same. Both have a ln audible continuity sensor which works with a k-type thermocouple probe. You just have to set the dial to Celsius or Fahrenheit (whichever is available) and plug the thermocouple probe carefully. The electrical difference between thermocouple ends will then be converted into temperature readings in the bigger LCD/analog display.
