I have a Fluke that's prolly 20 years old and a Wavetek that's at least 15. I've read that cheap DMMs may give faulty readings when the batteries are dying. That's not true for mine. Is there a good, middle of the road DMM that I can buy for my son, that doesn't get weird when the batteries start going south? _______________________________________________
what's middle of the road?There's a lot of DMMs in the $100 or thereabouts range that are quite nice. The old Wavetek 27XR beloved of coilers (measures capacitance!) 10 years ago has been discontinued but there's Meterman and Amprobe that are quite similar, if not better, and in the same price range. I think the Wavetek Meterman 35XP is the new one at about $80.
The $10 DMMs from harbor freight and similar discounters aren't bad and they are truly sacrificial.
What features/accuracy do you want? The $10 specials may have 4 digits on the display, but the accuracy and repeatability may not justify it. OTOH, if you just want to know if it's a 1k or a 5k resistor, and not distinguish between 1.123 and 1.124 k, then they're fine.
