possibility of reading millivolts(a.c.) with a voltmeter.

Greetings and thanks Conrad.

tonequester here. I actually had a guy from another forum advise me about Hamfests. I tried to Google for anything around the Kansas City area, but had no luck then. I'll check that option again though. The advice about turning your back on something that you want is well noted. I appreciate ALL of your tips, Sincerely, tonequester.

I'm returning back to this topic because I realized that this questions has been fundamentally answered in the wrong way. Quite simply, you don't state how much accuracy or precision you want. I often find that for me precision is more important that accuracy because I am doing relative comparisons, more than needing exact values. Typically when I am making measurements, I am doing comparative so when I measure 2.00004V, I want that same value to always read 2.00004V. I don't care if it is actually 2.00004V or 2.11103V just that the precision is the same. So for things like mV AC I use either my Keithley 199 or my UT61E. The Keithley has high resolution and better accuracy (0.15%+-200 counts for the 300.000mV range), while the Uni-T UT61E is a damn good all around hand held for the price (under $60 with 20,000 count resolution).

Greetings PedroDaGr8.

I have printed off your post for future reference, hopefully not to far away. I appreciate your time. I get "the drift" about accuracy vs precision. i guess that at the point I am at present, accuracy would be my more immediate goal. I'm not doing any thing one would consider relative. Some troubleshooting from scratch, at times without schematic. Also, still modding/experimenting with guitar and tube amp. Bouncing back and forth not only between guitar and amp, but between buying parts/components and test equipment/tools of the trade. Thanks again for your helpful advice. It's greatly appreciated. I'm beginning to get into a lot of "new territory now ! tonequester out.

One other thought. I have lots of meters to read down to a mV and below, but don't use them that often. What I use all the time is the high gain plug-in for my scope. That goes down to 10 uV/division and I use it to investigate noise and ground issues with audio equipment. IMO, a high gain preamp for your scope would be more useful than a meter. Just be sure to include some low pass filters. 😎

Greetings Brian Oshman.

Thanks for the recommendation for the Simpson 260. My dad has always sworn by Simpson meters, and I do believe that most who would know, would feel the same when talking analog meters. I have found analog meters to be a "must have" for many applications. I will be looking at getting a QUALITY one soon, and I will check into the model that you suggest.

Thanks for your advice, and glad to "meet" you here !
