Explains why it can't be used on PCBs.For some reason ~2.5kΩ refers to low impedance, and seems standard for eliminating measurements caused by Capacitive inductance

Depends on the task at hand.sure, but in auto-range mode there is no "setting" of the dial. it can read only up to its max and down to its min, etc.
and i do not disagree with you, one needs to be fairly confident about what it is they are about to measure. crazy bizarre accidents do happen, but hopefully we keep those events rare.
Well reading this thread, I have to say I got what I deserved, but I did buy a Mastech MS2115B True RMS clamp meter. Here I am about 6 months later looking at a blank display. This was a meter I got and kept for convenience, I left in my truck should it ever come in handy when I didn't have my tool bag.
I probably used it about 10 times total (including playing with the new meter) used it on a truck fuel pump and put it away. Brought it out again for whatever reason and nothing but a blank display. Of course I tried new battery.
I contacted the vendor I bought it from, No reply.
I contacted Mastech from an address on their webpage, I did receive a response, they directed me to their US branch.
I contacted Mastech US, No reply.
Lesson learned (again), does anyone know of service center or working contact number or address?
Its a shame, I did like the meter, it was around $70. But $70.00 for 10 uses is a bit high.
Buyer Beware
A word of caution about leaving meters in your vehicles then using them to measure voltage. I was shown a really nasty picture last week where a meter that was always kept in a truck had moisture condensation inside. That caused an arc flash when the user tried to measure voltage. I presume he was on a 480/277 system, but that was not stated, neither was the brand of meter.
