Description
AITRIP Transistor Tester GM328A Voltage Frequency Waveform Meter LCD Display R Inductance Square Signal PWM Diode Capacitance Generator Multifunctional sy Operate Resistor
Use 9V battery(not included), can also use DC power(DC 6.8-12V)
Automatically detects NPN and PNP transistors, FET, diodes, dual diode, thyristor, SCR, automatic identification of the transistor pinout.
Can be used as signal generator and frequency meter: frequency range from 1Hz-2MHz and can generate 1%-99% PWM(pulse width modulation) signals.
Main chip is the DIP, easy for electronic enthusiasts to DIY or update the main chip.
Notice: Before measuring capacitance, the capacitor must be discharged, otherwise very likely damage the meter.
