Rated 4 out of 5 by from I need this for work I like Fluke meters and in the past, the amp/ volt meter did not check capacitance. After losing my last meter I decided to spend more than twice as much money and get the meter that will do what I needed. I am glad I did, I can tell this meter is better than a cheaper fluke meter. The dial moves better, the buzz is louder. I got lucky and the leads are better. The one thing that would make this better, I use my meter several times a day just about everyday. Because of that I leave the leads attached. The bag that comes with it is to small if you leave the leads attached. They should make the bag bigger, the bag can help protect it like water or rain.

Rated 4 out of 5 by from Almost perfect I work in commercial/industrial HVAC and this meter checks almost all the boxes for me. The only downside is no magnet and the magnet accessory sold by fluke does not work with it. But Amazon has magnet bars with double sided tape that fixes that issue.

Rated 1 out of 5 by from Disappointed Bought meter in august 2018. Changed batteries for the first time and one of the negative contacts for battery was broken off. Never had the battery cover off before. Called fluke and was told I could ship the meter back to them at my cost and they would send me a new one for a slightly discounted price! Will not purchase another fluke !

Rated 1 out of 5 by from Did not last! I bought the Fluke 324 in August 2019. Meter stopped working in November 2020, showing a display message of "Low Battery". I replaced the batteries with a new set and still the meter won't work! Doesn't matter what batteries I put in the meter.. still doesn't work! For the amount of money I spent on this meter, and the fact that I take very good care of my tools.. I believe this meter should have lasted A LOT longer than it did! According to the Fluke web site, the warranty is for one year. My meter stopped working 3 months after the warranty period!
