ITEM NAME:Multifunctional Lcd Gm328 Transistor Tester Diode Capacitance Esr Voltage F X7F5 Multifunctional Lcd Gm328 Transistor Tester Diode Capacitance Esr Voltage F X7F5 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.Rotary switch control, a key measurement for convenient use. 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. Measure FET gate threshold voltage and gate capacitance.Automatically test the pins of a component and show on the display.Digital LCD display for easy readings, can display measured data and image. 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. Display: 160*128 LCD Current: Approx. 30mA Capacitance Measurement: 25pF~100mF Capacitance Resolution: 1pF DC Voltage Measurement: Up to 50V Notice: Before measuring capacitance, the capacitor must be discharged, otherwise very likely damage the meter.
