Description: Multi-functional transistor tester is used for automatic detection of NPN and PNP transistors, N-channel and P-channel MOSFET, diodes, thyristors, resistors, capacitors or other devices. Easy and convenient to operate. You deserve it! Features: Can be widely used to detect NPN and PNP transistors, capacitors, resistors, diodes, transistors, N-channel and P-channel MOSFET, IGBT, JFET, triacs and batteries. It can also detect zener diodes and has its own calibration function. After the test, align the IR remote control with the "IR" indicator, then press the button on the remote control. If the detector decodes successfully, the data code and the infrared waveform are displayed. The display is 3.5 x 3cm TFT full color screen. Lightweight, compact, convenient to carry. Specifications: Display: 3.5 x 3 cm / 1.38 x 1.18 inches TFT screen Diode range: less than 4.5V Zener diode: Transistor detection area: 0.01-4.5V; Zener diode Detection area: 0.01-30V Three-terminal thyristor switch range: IGT less than 6mA Capacitance: 25pF-100mF Resistance: 0.01-50MΩ Inductance: 0.01mH-20H Battery: 0.1-4.5V Product Size: 8.8 x 8 x 2.8 cm / 3.47 x 3.15 x 1.10 inches Package Weight: 140g Functions: Transistor Tester: Automatic detection of NPN and PNP bipolar transistors, N-channel and P-channel MOSFETs, JFETs, diodes (including double diodes), N- and P-IGBTs, resistors (including potentiometers), inductors, capacitors, thyristors, triacs and battery (0.1-4.5V) Automatic detection of zener diode(0.01-30V) Self test with automatic calibration IR decoder: Support Hitachi IR coding IR waveform display Infrared receiving instruction Other function: Measurement results using TFT graphic display One key operation Auto Power Off (Shutdown Time Settable) Built-in high capacity rechargeable Li-ion Battery Li-ion Battery voltage detection Support Chinese and English Package List: 1 x Transistor Tester 1 x Electronic Component Group (Randomly Send) 3 x Test Hook (Randomly Send) 1 x USB Cable Note: 1. Before test, discharge the electronic components to protect the detector. 2. When the voltage and internal battery voltage is less than 3V, please charge it before use. 3. Please use a 5V battery or USB interface to charge. 4. The color in the pictures may slightly differs from the actual item due to the light shooting and different displayers. 5. The measurement allowable error is +/- 1/3 cm.
