It weird that it seems to read fine with a 2 ohm leaded 1/4w resistor but not with a soldered 1 ohm smt one.
Yes, very rogues! Why did not they use 1 ohm resistor?
I'm sure it's some kind of firmware bug at a range crossover point maybe.
Yes, maybe a wrong value on one interpolation table, or something like that.
The problem isnt bad enough that I'd toss it in the bin and buy a Keysight meter.
That is relative.
I expect and accept there maybe (will be) firmware problems with cheap gear.
Yes, this is an "economic" instrument, and designed and made in China, but that should not be an excuse.
Maybe they never will recognize this fault, especially if only they can load a new firmware.
Also, if all the IET meters have this bug, what will be their reaction?
