DollaTek DIY GM328 Transistor Tester LCD Diode Capacitance ESR Voltage Frequency Meter PWM Square Wave Signal Generator

• Digital LCD display for easy readings, can display measured data and graphics.
• Rotary switch control, a key measurement for convenient use.
• Main chip is the DIP, easy for electronic enthusiasts to DIY or update the main chip.
• Use 9V battery(not included), can also use DC power(DC 6.8-12V).
• Automatic shutdown, shutdown current is only about 20nA.

DollaTek trademark Reg.NO:013726393 Features: Automatically detects NPN and PNP transistors, FET, diodes, dual diode, thyristor, SCR, automatic identification of the transistor pinout. Test NPN and PNP transistor common-emitter current amplification factor, the base-emitter threshold voltage, off the collector - emitter leakage current. Support 2 resistors measurement, show its positive and negative, on-state voltage. Resistance measurement maximum resolution 0.01Ω, can be measured up to 50MΩ. Automatically test the pins of a component and show on the display. Measure FET gate threshold voltage and gate capacitance. For the following 2100Ω resistor while measuring its inductance measuring range from 0.01mH - 20H. Can be used as signal generator and frequency meter: frequency range from 1Hz-2MHz and can generate 1%-99% PWM(pulse width modulation) signals. Notice: Before measuring capacitance, the capacitor must be discharged, otherwise very likely damage the meter.
