DIY LCD GM328 Transistor Tester Diode ESR Meter PWM Square Wave Generatorbrand: SainSmart SKU: 101-30-255
Multi-functional transistor tester for automatic detection of NPN and PNP transistors, N channel, P channel, MOSFET and JFET, diodes, dual diode, thyristor, automatic identification of the transistor pinout. It also can be used for frequency measurement and PWM signal generator.
Before measuring capacitance, the capacitor must be discharged, otherwise very likely damage the meter.
Be sure to disconnect the power from the circuit board when testing the components on the circuit board, the test equipment have residual voltage is not allowed.
