Multi-functional transistor tester for automatic detection of NPN and PNP transistors, N-channel and P-channel MOSFET, diodes, thyristors, resistors, capacitors or other devices. Also can be used as square signal and PWM signal generator.
Features:
Digital LCD backlight display for easy readings, can display measured data and graphics.
Micro-controller uses 8MHz external crystal, the measurement accuracy is better.
One button operation, easy for use(long press the button and enter the menu selection).
Main chip is the DIP, easy for electronic enthusiasts to DIY or update the main chip.
Can be powered by 9V battery(not included).
Automatic shutdown, shutdown current is only about 20nA.
Automatically detect NPN and PNP transistors, N-channel and P-channel MOSFET, JFETs, diodes, inductors, resistors, capacitors, thyristors, etc.
Support 2 resistors measurement, also support potentiometer measurement.
Resistance measurement resolution is 0.1 ohms, 50M ohms can be measured.
Automatically test the pins of a component and show on the display.
Measure the gate threshold voltage and gate capacitance of the MOSFET.
Measure bipolar transistor current amplification factor and base-emitter threshold voltage.
Can be used as signal generator and frequency meter: built-in square signals 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.
Users need to add an interface with some components by themselves if they want to measure the frequency(1Hz-2MHz)!
