Hello everyone, I have a problem again.
This time with a Fluke 75.
The error lies in the fact that a value of 0.00 ohms is not possible when measuring the resistance.
If the input is short-circuited, the measuring device starts at approx. 20 ohms and runs to a final value of 1.2 ohms in approx. 1 minute. (see pictures).
I have already tested internally without the connection socket. Same error pattern.
Thus the bushings can be excluded. The cable is new and tested on other measuring devices. It looks like a capacitor is changing?!?!

Does anyone have an idea or knows the problem? I checked the various internal resistances. All OK.
What is also noticeable is a similar problem with the diode/continuity test.
It takes a certain amount of time until the value approaches 0.00.
It won't be quite 0 either.
Continuity testing works immediately and has no problems.
