Description: Brand new and high quality. Function: Multifunctional transistor tester for automatic detection of NPN and PNP transistors, FET, diodes, dual diodes, thyristors, SCR, automatic identification of transistor pin position. It can also be used as a square wave signal and PWM signal generator. Digital LCD display for easy reading, can display measured data and graphics. Rotary switch, one-button measurement for convenient use. The primary circuit is DIP, easy for electronics enthusiasts to DIY or update the primary circuit. Uses 9V battery (not included), can also be used for DC power (for DC 6.8-12V). Automatic shutdown, shutdown current is only about 20nA. Automatically identifies NPN and PNP transistors, FET, diodes, dual diodes, thyristors, SCR, automatic identification of transistor pin position. Tests the current amplification factor of NPN and PNP transistors, base-emitter threshold voltage, collector-emitter leakage current. Supports 2 resistor measurements, displays its positive and negative, turn-on voltage. Resistance measurement maximum resolution 0.01Ω, can be measured up to 50MΩ. Automatically tests the pins of a component and displays on the screen. Measures FET gate threshold voltage and gate capacitance. For the following 2100Ω resistor, while measuring its inductance, measurement range from 0.01mH - 20H. Can be used as a signal generator and frequency meter: frequency range from 1Hz-2MHz and can generate 1%-99% PWM (pulse width modulation) signals. Note: Before measuring capacitance, the capacitor must be discharged, otherwise, it is very likely that the meter will be damaged.
