Additionally, Fluke appears to be removing critical reviews from their corporate website. I posted a review of this product pointing out this feature limitation and it was removed within a week.
In short, if you need average voltage or current, you will need to look at a different product.
This meter is the top meter in the 320 series. It has features (not in the 323, and 324 meters) that were important to me, like frequency (measured with the clamp-on, not the probes), used for VFD drives, higher Ohm scale and DC Amps (which is not a premium on other brands).
The unit is dead accurate and fast. All readings are spot on, without calibration. The volts/amps RMS work great on dirty NYC sine waves, and cleaned up VFD digital waves.
The exterior is durable, the operation is predicable and to the point.
Very reliable, and I feel safe with it.
The price is high, almost to high, compared to the 323&324 models
You can get cheap meters from Fieldpiece & UEI and better meters from Sperry, Amprobe, Hioki, Agilent that are cheaper with more features, but Flukes are the best built (besides Simpson), with the best components --- like capacitors.
The amperage only goes to 400 Amps, which is kind of low.
Temperature probe is not "K" type, but plugs into the probe sockets.
(Sorry if I pissed the Fieldpiece meter fans, I don't like them)
Its really handy when working on an air conditioner on the roof and needing to know if fuses are good or bad--but not wanting to open the fuse box with 230V going into it. (the fuse is on the AC unit). So voila, you clamp onto the wire and instantly you know if anything is flowing through that wire. If yes, fuses are good. If no, fuses might be bad, but at least you know quickly, easily, and SAFELY.
It also has an alarm to beep if a short or open circuit (which can be turned off).
You can spend more, but you can't get better. Just ask any of us who use these in our careers and any number of us will vouch for FLUKE quality and reliability.
One question recently asked about this meter was if you can measure current using the test leads (series connected current measurement. The answer is "no," and the manual specifies to disconnect the test leads before measuring current using the clamp jaws.
Speaking of the manual, it's pretty useless... Instead of text describing the features, it uses cryptic pictograms to attempt to convey complex ideas. Head to Youtube to see videos of how to use the meter if you're unsure. If you've used a similar meter in the past, it's pretty easy to figure out how to work this meter.
I recently did some testing of a 3 ampere circuit breaker to determine the overcurrent trip point. I used an HP DC power supply (with built in current measurement) and a Fluke 87-5 connected in series to monitor current (just to verify accuracy). For fun (and to satisfy my curiosity), I also clamped the Fluke 325 onto the test lead. Unsurprisingly, the three meters (power supply, 87-V, and 325) all matched within 0.10 amperes of each other. Very gratifying and reassuring to see such demonstrated accuracy.

This is a fine product for measuring current or voltage, but the ohm function is a joke. I build coils for a living and consistent and reliable readings are key. Read morePublished 1 month ago by Brad
