Review on ICQUANZX LCR TC1 ESR Tester: A Comprehensive Meter for Transistors, Inductance, Capacitance, and Resistance by John Fuentes

First off if you think you need to buy this and learn how to use it think again as there is absolutely NO documentation as to what whatever it is. There isn't even a manufacturer website where you can find an ant type guide. It took me quite a while to find a YouTube video that explained some of the features. The one I installed was a guy who called himself "Battery Doctor" and compared his characteristics to an older device. Once you figure out what each part of the socket is for, the learning curve will decrease. For example, the top left side of socket number 1231 is where you will do most of your testing, and it is unpolarized, even for diodes. However, if you want to test the zener diode, you must do it in the part marked KAA1 below and in the polarized part of the socket. Anyway, I just wanted it for simple capacitor testing and it does it well. Now I know which part of the socket to use. I only gave 2 stars just because of the lack of documentation. Good luck but be careful
