Would something like this Klein multi meter be adequate for $31, or do you have to spend $100 or more to get something reliable?
There are a few thinks about it I do not like:
1) Combined terminal for mA/uA and Volt
2) The precision is a bit low for LiIon batteries, when it shows 4.20 the actual voltage can be between 4.15 and 4.25 volt.
3) No burden voltage specified for current range, i.e. the mA/uA range might not even be usable for flashlights.
4) The diode test is only 1.5 volt and cannot be used for leds.
I do like that it has auto range, includes a temperature probe and has back light.
