Package Includes: 1 x Transistor Tester (battery not included) Available Models: Model 1: Case Color - Colorful Model 2: Case Color - Gray Features and Specifications: Key Features: 128 x 160 TFT color display for easy readings, capable of displaying measured data and graphics. Powered by a 9V battery (not included). All components protected by a plastic case, making it convenient to carry. Automatically detects NPN and PNP transistors, N-channel and P-channel MOSFET, diodes, thyristors, resistors, capacitors, and other devices. Automatically tests and displays the pins of a component on the LCD. Measures gate threshold voltage and gate capacitance of MOSFETs. Measures bipolar transistor current amplification factor and base-emitter threshold voltage. Two-button operation with automatic shutdown to conserve battery life. Short detection time of only 2 seconds (note: bulk capacitor detection may take up to 1 minute). Notice: Please ensure capacitors are discharged before testing.
