[Discontinued] DIY LCD GM328 Transistor Tester Diode ESR Meter PWM Square Wave Generator restock_form 1x SainSmart SD RAMPS BreakoutDescription: 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. Notice: Before measuring capacitance, the capacitor must be discharged, otherwise very likely damage the meter. Be sure to disconnect the power from the circuit
