Small common mode choke (ferrite core):
1.39 mH result
Turn around get first 1.20 mH, then next measurement same direction 1.39 mH
Turn around again gets 1.20 mH and then 1.38 mH

Mains transformer low voltage coil 246 mH
Turn around 158 mH and next measurement same direction 234 mH
Tunr aroun 169 mH and next 245 mH

Another signal transformer 0.53 mH
Other way 0.52 mH next 0.53 mH

The unit is very handy however it has problems with certain type of Triacs.

I bought one of these from eBay ages ago when they were really cheap. It’s so useful for quick checks when assembling circuits. I love mine

It is a cheap tester and good for quick tests but I also use a curve tracer and other more expensive test equipment . I do not trust it completely The Unit is OK for a quick test, diodes, caps resistors as well as inductors. However, the Tester I have will show a PNP such as a bdx 34x c as a NPN. It often makes the mistake of identifying the correct polarity of a darlington. I do not trust it at all in that respect. Regular bipolar, Mosfet check ok. 4401, 2n2222 and other small signal all check properly except mpsa13 npn darlington small signal T092 checks as a PNP one time and an NPN another time! . Have used it hundreds of times and it the only other flaw is that the bottom of the display where the #3 probe on the video is .. that is washed out. A good value for a cheap tester.
