When you short the probes, does the meter read 0.1 ohms?  If not, what does it show?

Measure the resistance between the terminals with the meter off using another meter.

If shorting shows 0.1 ohms, what does it show for a 100, 1k, 10k and 100k ohm resistor?

Hi @Tizi, did you ever get to the bottom of the error? I have exactly the same issue on my MT22...

Thanks!
