## Description

Note:Please make sure that capacitors are discharged before testing.Specifications:Case Color: GrayDisplay: 1.8&quot; TFT Color DisplayMaterial: PCB + PlasticShutdown Current: 20nAResistor Test Range: 0.5&#x3A9;-50M&#x3A9;Inductor Test Range: 0.01mH-20HCapacitor Test Range: 25pF-100000uFItem Size: 13.5 * 7 * 2.2cm / 5.3 * 2.76 * 0.86in Item Weight: 99g / 3.5ozPackage Size: Approx. 16 * 8 * 2.5cm / 6.3 * 3.15 * 0.98inPackage Weight: 102g / 3.61ozPackage List:1 * Transistor Tester (battery not included)

## Features

- Two-button operation, automatic shutdown to avoid unnecessary waste.
- 128*160 TFT color display for easy readings, can display measured data and graphics.Powered by 9V battery(not included)
- Automatically detect NPN and PNP transistors, N-channel and P-channel MOSFET, diodes, thyristors, resistors, capacitors or other devices
- Short detection time: only 2 seconds. It is normal to cost 1 minute for bulk capacitor detection.Automatically test the pins of a component and display on the LCD.
- Measure the gate threshold voltage and gate capacitance of the MOSFET; Measure bipolar transistor current amplification factor and base-emitter threshold voltage
