Feature:1. 160x128 COLOR DISPLAY: Capacitance inductance meter display unit uses 160x128 color display with 8x20 characters, 16bit color depth, and graphic display of component symbols.2. ONE TOUCH MEASUREMENT: The Resistor transistor tester is controlled by a rotate encoder switch for one touch measurement and automatic shutdown.3. IDENTIFY TRANSISTORS: Test NPN and PNP transistor co emitter current amplification coefficient, base and emitter threshold voltage, collector and emitter leakage current at cut off. Emitter threshold voltage and high current amplification factor identify the triode.4. BATTERY POWER SUPPLY: Use 9V laminated battery power supply, also can use power adapter power supply, the whole machine current about 30mA, after shutdown current about 20nA.5. APPLICATIONS: Automatic detection of NPN and PNP transistors, field effect tubes, diodes, double diodes, thyristors, SCRs, automatic judgment of the transistor pin distribution.Specification:Item Type: GM328 Transistor TesterMaterial: PCBDisplay PX: 160x128Number of Characters: 8x20Color Depth: 16 BitsAdditional Functions: Including Frequency Measurement, Voltage Measurement, Waving Generator, Pwm Generator, Infrared Remote Control Decoding, Infrared Remote Control Encoding, Temperature Sensor Test, Temperature and Humidity Sensor Test, Color Selection, Debugging Calibration, Continuous Test, Etc.Color: Black.Package List:1 xGM328 Transistor Tester
