Introduction: What is the LCR T7? The LCR T7 is a popular, multi-function handheld tester primarily designed for hobbyists and electronics repair technicians. It is a modern iteration of the classic AVR-based component testers (like the famous “Transistor Tester” by Markus Frejek and Karl-Heinz Kübbeler). The device automatically identifies and measures resistors, capacitors, inductors, transistors, diodes, FETs, SCRs, and more. make clean make This generates TransistorTester
