Multifunction transistor tester for automatic detection of NPN and PNP transistors, FETs, diodes, double diodes, thyristors, SCRs, with automatic transistor pinout identification. It can also be used as a square-wave signal and PWM signal generator.
Features:
Digital LCD display for easy reading, can show measured data and graphs.
Rotary switch control, one-key measurement for practical use.
The main chip is a DIP, easy for electronics hobbyists to tinker with or to update the main chip.
Uses a 9V battery (not included), can also use a DC power supply (DC 6.8-12V).
Automatic shutdown, the shutdown current is only about 20nA.
Automatically detects NPN and PNP transistors, FETs, diodes, double diodes, thyristors, SCRs, with automatic transistor pinout identification.
Tests the common-emitter current amplification factor of NPN and PNP, the base-emitter threshold voltage, and the collector-emitter leakage current.
Supports measuring 2 resistors, showing their forward and reverse voltage, and their state.
Resistance measurement with a maximum resolution of 0.01R, measurable up to 50M.
Automatically tests the pins of a component and displays them on the screen.
Measures the FET gate threshold voltage and the gate capacitance.
For resistance of 2100R and below, while measuring its inductance measurement range of 0.01mH-20H.
Can be used as a signal generator and frequency counter: frequency range of 1Hz-2MHz and can generate 1%-99% PWM (pulse width modulation) signals.
Notes and remarks:
Before measuring capacitance, the capacitor must be discharged, otherwise it will very likely damage the microcontroller.
