Description
Transistor Tester GM328A Graphic Patch Version Transistor Tester Finished Board Auto Detect PNP NPN Bipolar Transistor
Product Description
1. Use the 2015 V1.12 version of the software. 2. The power supply uses 9V stacked batteries. 3. The download interface is a standard 6-line program. 4. 12864 dot matrix LCD screen, rich in content, with pictures. 5. Use 1/1000 thin film resistors for the effect of the relative resistance accuracy, and the rest are also used for 1/100 thin film resistors.
Function
1. Can automatically detect PNP, NPN bipolar transistors 2. Automatically identify the components of the pins. 3. Capacitance can be measured 4. It can detect the protection diodes of bipolar transistors and MOS tubes. 5. It can display the decimal value of 2 and the resolution of 0.01 ohm. 6. Reverse breakdown voltage lower than 4.5V regulator can be identified. 7. Gate threshold voltage and gate capacitance of MOS field effect transistors. 8. It can measure two resistances at the same time and display the resistance symbols. 9. The resolution of resistance measurement is 0.1 ohm, and it can be measured as 50M ohm. 10. Capacitors above 2uF can measure the ESR value of equivalent series resistance at the same time. Two diodes can be displayed in the correct order and diode symbol, while giving the forward voltage of the diodes. Only a single measurement can obtain the connection pattern of the rectifier bridge.
