Fluke 323 VS. 324 Review: Clamp Multimeter Comparison Guide

Fluke 323 and Fluke 324 both are clamp meters for electrical measurements. The main difference between a multimeter and a clamp meter is that you can use a clamp meter without worrying about cutting the wires. As Fluke 323 and 324 are both from the same series (same company), it is quite confusing to choose between these two. Clamp multimeters measure voltage, currents, continuity, and resistance with great accuracy.

Both these meters will offer you top-notch features and reliable performance with an ergonomic design. So, which one are you going to choose?

Measurement of the electrical difference between two devices that possess voltage in them is known as capacitance. Fluke 323 does not provide capacitance feature, whereas Fluke 324 meter provides capacitance feature. 324 can also measure the capacitance of 0 microfarad to 100 microfarad and 100 microfarad to 1000 microfarad (µF).

Fluke 323 vs 324 vs 325 Review

If you look at these three clamp meters with the naked eye, you can’t see much difference. When you look into the price, you can see there is a great difference. Why so? Because there are certain features unseen in the older versions.

All the versions have some common features. All the 323, 324, 325 clamp meters have AC Current checker up to 400A. Also the AC/DC voltage is same; 600V.

However, there is no capacitance, temperature and backlight are in play in 323 whereas, 324 and 325 both the meters have had them.

Fluke 325 comes with a frequency meter and DC current whereas the 323 and 324 don’t have these features at all.

Key features of Fluke 323 and Fluke 323 Review 2021 [True RMS Clamp Meter] 

Fluke 323 is a basic troubleshooting clamp multimeter for commercial and residential electricians. Fluke 323 Meters measure ac and dc voltage, ac current, resistance, and continuity.

Fluke 323 multimeter

True RMS: As the Fluke 323 is a clamp meter instead of a premium multimeter, this is a great feature to have. What will you do with this feature, anyway? For instance, to get readings from a sine wave, a non tRMS will do the job perfectly. But in the cases of square waves, you will need a true RMS meter to get accurate readings.

What if you want to get readings of RMS value with square waves with a non tRMS meter? In that case, you won’t get 100% accurate results. Well, you will get results. But if you care for accuracy, you should not go for a non tRMS meter. 

Can measure resistance: The 323  which is also noiseless, can also measure resistance. The figure here is 4000 Ohms. Although this figure may seem not much useful, this is not the case here. The purpose of the creation of 323 was to provide you a portable device eliminating every kind of risk. You will be able to measure up to 4000 Ohms. This is quite good and can almost cover every light and home task. 

Can measure Continuity: You can also measure continuity with the Fluke 323. In terms of continuity, you will be able to get readings of any figure that is less than 70 Ohms. Again, these meters are not that good for heavy tasks. You have to use them in your home or to complete any light task. In these cases, the 70 Ohms figure will serve you just fine. 

CAT IV safety rating: For what reasons do you need the CAT safety rating? With a CAT safety rating, you get a rough idea about how safe the meter you are using or going to use. The 323 has a CAT IV safety rating of 300V. Actually, CAT IV is the highest safety rating in terms of practical experiences.

For the most dangerous and highest level of overvoltage, technicians depend on these CAT IV-rated meters. If the device is not CAT IV rated, you can’t do any work when there is an overvoltage issue. That means our 323 is great for even industrial works in terms of overvoltage. 

Features of the Fluke 323 Multimeter:specifications

  • DC and AC voltage readings are 600 V
  • AC current readings are 400 A
  • Measures resistance to 4 kΩ with continuity detection
  • It can read continuity of less than 70 Ω
  • Features a CAT III 600 V, CAT IV 300 V safety rating

Pros and Cons of Fluke 323

Pros

  • Can measure both AC and DC Voltage: Having an all-rounder product is always a plus. And if you have a product like Fluke 323 that can measure both AC and DC voltage, it will be amazing, isn’t it? Can also measure linear or nonlinear loads.
  • Good accuracy: As the 323 is a True RMS ac device, it is more accurate than the devices that are not tRMS. That means 323 Fluke is a born winner. But can you deal with situations where a slight difference in the readings can affect your work with the 323? Well, reviews say you can. 323 is fairly accurate to get the job done if you are craving for accuracy.  
  • Display hold: Fluke 323 has the display hold feature. As there is no Minimum/ maximum (min max )mode to give you a better idea about the reading, you can use the display hold as a proxy. You can freeze the readings manually with the use of the display hold feature. It will come in handy if you are in a dire situation where it is extremely necessary to hold a reading.  

Cons

  • Absence of backlit: This is a big deal-breaker for you if you need to work on night shifts. There is no backlit feature in the Fluke 323 meter to help you in the darks. In this case, either you have to use a separate light source or work on day shifts. And if the situation demand is extreme, you have to look for other options. 
  • The case is a bit tight: Too good is not good sometimes. Though a tight case may help protect the product better, it is not good for swift situations. Maybe you need something a bit flexible to get the job done quickly. The case of the 323 is a bit too tight (slim) for the job.
  • Can’t measure DC-amps: Too pumped with the feature of ability to measure both AC and DC voltage? You should not. Fluke 323 can’t measure DC amps. Disappointed a bit? If this is a serious and deal-breaking point, you must choose another option.  

Does Fluke 323 measure DC current?

No, Fluke 323 cannot measure DC current. In fact, 323 can measure AC/DC voltage, AC current, continuity, and resistance. But still, 323 does not measure DC current. The same goes with the Fluke 324 and 325.

How to use Fluke 323 Clamp Meter?

  1. Turn the dial to A ac or A dc and make sure the measurement is coming from the jaw by seeing the jaws icon on display.
  2. While taking the measurement of DC current, make sure your display is stabilized and push the zero button so that you can get correct readings.
  3. Press the jaw release level first, then open the jaws, and then insert a conductor so that it can be measured inside the jaw.
  4. Shut the jaw and use alignment marks on the jaw to center the conductor.

Check on the display to view the reading.
