Nice little tool,

Where have this been all my life! This small device is the greatest tool in my lab! It automatically detects the passive device and tells you the value. It’s so easy to use, features resistoance, capacitance, inductance readings with high accuracy. It’s very ergonomic and very thoughtfully designed. Better than your traditional multimeter and is a MUST HAVE!

These are awesome nice and small with inductors included in the test I find them to be more accurate than my uni t one and the case is a great addition to keep them dust free and safe.The unit has a 3 set frequency test condition which if it is slightly out you can set a different frequency and I have tried this and it does work quite well,There is a spare set of tips and they are right angled,I am happy to give these 5 stars as I think they are awesome.

Works great. Perfect for identifying tiny SMD parts. Easy to read display. User documentation (English version) is adequate, but a little hard to follow.
