I had this, it was making too many errors so I gave it to a fellow student.
Very often it will measure single coil inductance of relatively high value (1mh and above) as an IGBT transistor :D

I consider it a toy, and toys are fun. 😉 But it's cool that it can actually do some stuff.

I haven't found a spec sheet, I wonder what it claims it can accurately measure for inductance.

I used to use the TC2, which had a strange interface, then got the TC3 a chance. I am doing a lot of old analog restoration stuff, sometimes just checking, whether one of the components are dead. Indeed it "identifies" components erroneously at first try, but knowing, what I am inserting, it is just "try it again" and it does its job. I double check every now and then parts like capatitors with a multimeter - getting identical results.

So as an inexpensive all-in-all ting, I am quite satisfied with it.

Thanks! That spec sheet either isn't accurate, or there definitely needs to be some more firmware updates. I would guess both. 😉

On my reference board I had no trouble testing 1mH, 10mH, 100mH (1mH is the max on the spec sheet??), but I couldn't test anything lower than 1mH. R and C were both fine for what's in spec, except I couldn't test 100pF.
