Is the BM235 multimeter enough for audio and PSU work?

Just noticed the new Brymen 869s has the ability to measure ac + dcV and ac+dcA, in addition to the usual ac and dc ranges.

If you have to buy one dvm, buy a good one, and you can go wrong with Fluke. there are a lot available used on ebay, they are built to last a lifetime, keep their accuracy, meet their specs, and are safe, especially on HV if you work on tubes. I bought an expensive one 20 years ago and it is still my most usefull piece of test gear. Btw worked for 10 years in a calibration lab, and Fluke were some of the best!

My first Fluke 8060 was from '86. A few years later I picked up another on eBay at a very good price mainly
because the listing had spelling errors in the title and wasn't getting any views/bids. The seller wasn't happy
but I got the meter. I was testing some new video boards from the assembler and checking the 5V reference
supply which always read 5.000 but 3 in a row measured 4.998. The references were Analog Devices
AD588KQ ceramic case 1mV max error. It was the eBay meter so I opened it and touched up the calibration
which is the only time I've touched up a meter but I still wonder who fiddled it up. The first Fluke was and still
is spot on. I thought the original (my every day meter) finally failed so I bought another eBay 8060 in
January this year for $30. I found that when I opened #1 meter to clean the display I missed a spacer around
the LCD which was why it was flaky so now I have 3 8060s, and 8050a and a 5.5 digit unit I never use. I used
the 8060s to calibrate analog audio in a commercial video dub house. At +4 dBm it resolves down to .01 dB
and is flat to 100KHz. Bottom line? Get a Fluke !

One thing to be wary of in high impedance high Voltage measurements is th 11Meg loading of the meter might
alter the reading too much. We had to get the high Voltage probe to measure a 200 Volt supply in a Sony BVP-30
broadcast camera way back when. This is not unique to Fluke but it's important to know.

Yes. It's a Cat IV meter. The 121GW is also fantastic because it can act as a data logger to either an SD Card, or over Blue Tooth.

A meter is not enough. Buy yourself a nice set of Pomona probe leads - alligator clips, grabbers and proper coax <-> banana plug adapters. I always use at least one clip of some sort that I only have one hand on a probe in a chassis.
