Years ago when I did in my MFJ meter, 50 ohms was reading 40 ohms. It was a real chore to change out the bad diode and calibrate.

After making all of the recommended changes, I hooked up my MFJ and got
>650 readings regardless.  When connected to a 75 ohm dummy load, it
reads completely normally, as does shorting the input (R=0_ If I had managed to damage the MFJ with DC voltage on the input, would you expect no readings at all (>650 everywhere)?
