** Time you measured the internal resistance of a DMM when set
to the 200 / 300 mA range.

A typical 3.75 digit meter I have here exhibits a whooping 5.5
ohms !!!

The voltage drop at full reading = 1.8 volts !!

Most of it is due to the 500mA glass fuse employed on that
range.

Your friend is right & you are 100% wrong.



So what make and model of piece of *** is that so i can avoid
buying one?



** Fluke 73 or Fluke 77 and many, many others.

Burden voltage is speced as " 6 mV per mA " on the 32mA and 320
mA
ranges.

Equates to a 6 ohm resistance.

Fuckwit.

I threw away an old fluke 77 years ago. It did ok on voltage on
voltage and soso on resistance. Another overpriced brand name
mediocre meter.
