Beginner DMM in $50 for guitar related diy
beachbuminthesun:
I’m at my wits end finding a multimeter that’ll function for everything I want to do. I am just starting out with DIY Ing guitar pedals and making my own tube amps. Heres the recommendations I’ve been trying to it i’ve been trying to adhere too from small bear electronics:
DC and AC Voltage - To 750 volts
500 millivolts voltage scale
DC and AC current - low-current scale, like 2 to 3 milliamps top, as well as a high-current range of several amps.
I also understand that TRMS would be good for testing out amps but I’m not sure if I would be better served by purchasing an affordable oscilloscope (if anyone knows a good value affordable one please jump in).
I was looking at the uní-t UT-139c but it’s not rated past 600 and there’s so many recommendations that it’s easy to get lost. Looking to spend as little money as possible and have a functional unit I won’t have to upgrade for many years.
Thanks

Hi. Welcome to the forum.
Yes, the UniT139 would be a good choice.
You could look at Amprobe multimeters, they are not as cheap as UniT but will be safe and reliable.
If you are interrested in waveforms, then yes a scope would be best.
Not sure if trms is useful for audio work.
Have you considered getting one good meter and one cheap one, like the cheap/free from harbour frieght?

I already have a fairly cheap one, but it is really really basic no name one. But I don't do enough work at the moment to justify anything over $50..

This subforum is more for precision DMMs and whatnot (a bit out of the $50 pricerange), but in the main Test Equipment forum there's a couple of pinned posts that have overview comparisons of dozens of models of multimeter, and since they tend to be of interest to folks on these boards, there should be a thread for most of the ones you'd consider for potential issues/features that they have. If you're going to search, don't use the bar on the top right, use the search icon on the top left, then enter your terms - for whatever reason it finds a lot more stuff than the other search bar.

If you would like to measure audio, a meter with higher bandwidth could be useful. However, these are more expensive (a new reasonable meter would be the Brymen BM857/BM867)
Did you look at the Klein MM600? It is not true RMS, but it goes to 1000V and it is a sturdy meter. The MM700 is TrueRMS variant. Both have lower bandwidth, though (probably around 1kHz).
Greenlee also has some very good 1kV multimeters (re-branded from Brymen), but they are more expensive. Look at the DM-200A, DM-210A, DM-510A.
