Do my eyes deceive me? Looking over the specifications, this $200 meter has WORSE accuracy than a $40 Fluke 101? Why? How?

Asked by: JosephW
Accuracy comparisons are based on the functions you are looking for in a meter. For instance, the Fluke 101 can not measure amps but the Fluke 323 can read amps up to 400 AC.

Asked by: Misha
Yes, the Fluke 323 True RMS Clamp Meter comes calibrated from the factory. If you require a traceable certification of calibration, you will need to request that service at the time of purchase.

Does this amp-meter compensate when reading Pulse Width Modulation output from VFD's? if so what is the KHz range of it. IF not do you have a handheld meter that can measure amps accurately on amps like the Mark 5 series does on voltage.

Asked by: PWM curious

The user manual shows it reads uf. Does it?

Rated 4 out of 5 by from Comfortable to handle and hold. I’m a first time Fluke user and was wondering if there is a printable online user instructional to enable me in making full use of this tool. Thank you for the follow-up.

Rated 2 out of 5 by from Not the quality I thought it would be ! Purchased model 323 used it twice and on third attempt the unit was dead! I owned it about 3 years, to be honest it spent most of its life on my boat. Totally disappointed I wanted a quality product, sorry for the bad news!

Rated 1 out of 5 by from 3 years old meter with a critical error Bought this meter 3 years ago maybe used 10 times. Went to use today First time in about a year. Meter came up with a critical error. Not what I expect from a fluke model. I would not buy Or recommend this fluke model. Fluke let me down when I needed it. I called fluke representative and was told out of warranty you got to buy another one I can’t help you. Buy another meter. Another meter that showed me dependability

Rated 5 out of 5 by from Excellent product! Using this in the field (in an HVAC capacity) has been wonderful and reliable, I would like to see some new innovations or products that utilize a smaller clamp that allows me to fit the device in tighter spaces, as measuring amperage in disconnects is a little cumbersome when line and load leads are tight. Otherwise it's a wonderful durable product that hasn't let me down.
