In this video we get a chance to review the Kaiweets ST100 and ST120 SMATECH meters. These are very affordable and provide us a excellent tool for troubleshooting. Featuring Auto function voltage, ohms and continuity. They also feature diode test, frequency, voltage detection, phase sequence and more. We look at how these two meters help diagnose a board on the bench as a real world test. The meters are small enough to throw in a car glove compartment, truck toolbox and in your small back-up tool bag to take to difficult locations such as rooftop or top of a silo bin if you need to travel light as possible and still have a handy meter. If interested we can also look inside of these meters in another video. I ran out of time for the frequency test and the teardown. If would like to see that, please let me know in the comments. Hope you find this video helpful. Thanks for watching.
