So im looking to pick up a decent DMM? is this something I should look for used or just buy new to avoid problems? Do they lose calibration at all? I'm looking for one that will last a LONG time and do whatever I need. (which isnt much, ive gotten by with a couple $20-$30 range so far.) but you never know what might pop up.
Also is fluke the only way to go? looking to spend around 100, so I figure if a used one is safer I can get a better one cheaper.
My knee jerk is always to buy second hand top quality over new second quality new. In this case, I'm quite sure you can find top of the range Fluke models for under $100. I recommend that approach.
If you decide to go new, there are a couple things you should know about:
1) Most inexpensive models will be made in China or Taiwan. Some are made from old twist ties and cardboard. This can create a real safety hazard.
2) I read several reviews. 2 models stood out: Uni-T and the Chinese Flukes (models 15B/17B).
3) Lead quality and alligator/probe quality is something to consider. Fluke accessories are expensive but generally worth it, safer, and more convenient to use. I eneded up buying a Fluke 15, but spent as much on accessories as I did on the meter.
4) For automotive, where currents and voltages are generally lower, I think you are safer with less DMM. Its when you start dealing with household currents that you need better gear. THAT SAID, you can still hurt yourself with 12V automotive systems.
