This Multi-Purpose Transistor Tester is your all-in-one electronics diagnostic tool! Features a 128*160 TFT color display for easy reading of measured data and graphics. Powered by a 9V battery (not included). All components are protected by a case for convenient portability. Automatically detects NPN and PNP transistors, N-channel and P-channel MOSFETs, diodes, thyristors, resistors, capacitors, and other devices. Automatically tests component pins and displays them on the LCD screen. Measures gate threshold voltage and gate capacitance of MOSFETs. Measures bipolar transistor current amplification factor and base-emitter threshold voltage. Simple two-button operation with automatic shutdown to conserve power. Fast detection time: only 2 seconds (may take up to 1 minute for bulk capacitor detection). Note: Ensure capacitors are discharged before testing.
