Is this meter capable of measuring milivolts.

Asked by: Jevin
No, the Fluke 325 True RMS Clamp Meter cannot measure millivolts. An alternative is the Fluke 376 FC True-RMS Clamp Meter, which can measure DC millivolts.

Rated 3 out of 5 by from Great Meter, The Test Leads Suck in Cold Weather I have just purchased a Fluke 325 Clame Meter and I love the meter so far but the test leads that come with this meter DO NOT LIKE THE COLD WEATHER! I have purchase a number of meters over the last 30 years and these leads have to be the worst that have shipped with a new meter ever. These leads are as user friendly as trying to drag as wild cat through an antique store by it’s tail (I happen to love cats by the way and would much rathr drags the Fluke purchasing rep by his or her tail rather than a cat). This is really too bad considering the price that Fluke charges for their test equipment compared to other vendors.

Rated 5 out of 5 by from Better than my previous one i had a UEI Multimeter prior to this (pretty much the same functions, but after years of use was beginning to glitch on certain settings). got this model in response to the need to have a very functional multimeter, and i am confident that it will surpass the predecessor. the labels are fairly straightforward, and the automatic scale change is vital when measuring different ohm ranges. i also needed the clamp-on ammeter so i could leave the device on the wire whilst checking other numbers.

Rated 4 out of 5 by from Good instrument, lame manual Basic functionality is as described. However, the "manual" is unintelligible. The pictures don't really work for me. Not sure what they are trying to say.

Rated 5 out of 5 by from 325 True RMS Clamp Meter Excellent meter! I bought the first one through Amazon. It was a cheap Chinese knock-off which I returned. Went to Fluke and bought the real thing! No regrets!

Rated 1 out of 5 by from Poor Quality and Support I have this meter(out of warranty). The battery terminals lost its spring effect making the contacts loose. On requesting the service center for replacement / repair service, they asked me to purchase a new meter for they have no spares and do not repair this meter any more.
