Transistor Tester GM328A Diode Capacitance ESR Voltage Frequency Meter PWM Square Wave Signal Generator SMT Soldering
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.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 0.01ohm, can be measured up to 50M ohmFor the following 2100ohm 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.Colour:blueMaterial:PCBPackage Contents:1 set x GM328A Transistor Tester(The accessories are shown in the picture)Only the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
