Probably the TC3 just got too complex for FNIRSI. The transistor tester code itself is an absolute miracle that needed years of debugging and lots of iterations. Putting it into another "all-in-one-wonder" may just be too much.

Hmm, now I have looked for a 5.1k resistor to check this.
The measurement on my TC2 is frighteningly accurate.  ;)
Is this an individual problem with your device?

KungFuJosh:
I never use it for this purpose, but mine detected 1.2k and 8.2k fine. Maybe you should try reflashing the firmware?

Phil1977:
Values <4kOhm and >6kOhm are correctly detected with my device too.

@KungFuJosh: Can you try 5kOhm?

I´ll just stay using a DMM for resistors.

IIRC, we had such an issue with the OSHW firmwares and a few odd testers a long time ago and fixed it by improving the filter for resistors in the diode detection function. My guess would be that someone didn't test that when porting the code (k-firmware in this case) to a different MCU.

Yes. I'll have to find one later though, that value is not in my bins. I'm sure I have one somewhere.

As well you should. LCR or DMM is the right tool for testing resistors. Also a lot easier than clipping things into the TC3.
