Rated 5 out of 5 by from Great features with Fluke legendary quality. I have a couple Fluke meters, the first I purchased around 1983 and it still works great today so when I needed a clamp meter for a specialty job I went straight to Fluke and am still impressed

Rated 5 out of 5 by from Great clamp meter For the price of the meter and the durability, it is worth every penny. I wish it had more features like the higher dollar clamp meters but again, for the price you pay, you are still getting the best quality clamp meter on the market today! The clamp meter is made quality, accurate on readings and extremely durable.

Rated 4 out of 5 by from Question I have a Fluke 323 but I am having some issues to read current with the clamp, what is the lowest current it can read? Max=400Aac, but min=??

Rated 4 out of 5 by from GOOD METER The meter price is reasonable, it is durable and reliable, but there are a few thing that keep it from being great one. The audible tone needs to MUCH louder and when the meter goes off (it has auto off) you have to rotate the function knob all the way back to the off position then back to the function you are using. Needs a on and off button or, the a function added such as rotate selector knob to the next function to activate it back on.

Rated 5 out of 5 by from Excellent Meter I bought this meter to use at work. My company supplies us with volt meters but they are not the quality of this Fluke meter. I have not found a meter as accurate as this one. You can not go wrong with this Fluke meter.

Rated 5 out of 5 by from Works as required I use the Fluke 323 as my go to meter for around the house. It is a little overkill for what I use it for, but as an Electrical Engineer - I like overkill with my electrical test equipment. I've used it for a few work related projects, it has never let me down.

Rated 4 out of 5 by from Great for the Price I've had this meter for a while and I can say it gets the job done. I really like the clamp, not only can you take amperage readings you can also use it to clamp on the equipment door for convenience. Meters are used for safety as well as information about the circuit and I can truly say I wouldn't trust my life with anything other than a Fluke!

Rated 5 out of 5 by from I love using this tester i use it everyday at work I bought it 2 years ago and I love it they are easy to use and light weight and very dependable

Rated 5 out of 5 by from Excellent Clamp Meter! Works great every time! Very reliable! Amp clamp is awesome for checking amperage when It would be less safe otherwise it has a CAT IV rating under 300V which I mainly use it for, so that gives me great peace of mind when taking readings. I use mine everyday and have no complaints!

Rated 5 out of 5 by from Trust my life with it as a commercial electrician I use this meter on a very regular basis and trust my life with it. I really like the size of this meter over some of the bigger meters that i have used it is small enough that on days that I am constantly using it, it fits nicely in my tool pouches without taking up too much room and still gives just as accurate readings as those bigger more expensive meters i also really like having the clamp even if i am not using it, i really like having the option to hang it in a panel and use it hands free. the price was also great when I bought this meter i believe i paid about 80 for it and have been super pleased, i was looking for a quality meter that wouldn't break the bank while being small enough to carry all day and still give me all the basics that I need to do my job. My only gripe would be that this model has the leads plug in on the bottom. This means you cannot leave the leads plugged in and still fit the meter in its case. So basically, every time I use it, I have to pop the leads back in, and every time I'm done, I have to unplug the leads. I've seen a similar Fluke model where the leads plug in on the front face. On that model you can at least leave the leads plugged in and still fit the meter in its case. Seems like a unimportant detail, but it does make life easier. Just something to note.

Rated 4 out of 5 by from TINY pouch Same Fluke quality as my other meters, but the pouch is too small to leave the test leads plugged in and still close it. Obviously no electrician input on that design. My other Fluke meters don't have this problem.

Rated 1 out of 5 by from ok unless you need to read resistors... it's not really worth the 100 or so dollars especially if your doing fire alarm and need to check resistors...this thing is durable but I really wish I knew it was really really basic. Not worth 100 bucks.

Rated 4 out of 5 by from Very good for high voltage, not so much for low-V Everything about this meter is perfect, except for one thing: the resistance measurement. It's range is only 400-4000 ohms. Pretty worthless for troubleshooting control board and low voltage control resistors. Other than that, it's extremely good. I wish I would have looked at that before buying, but every other meter I had could measure close to 1 mega ohm. Even the cheap ones.
