About KOOKYE Mega328 Transistor Tester Diode Triode
How to adjust contrast brightness? Visit this link to watch video: https://youtu.be/wEnZgidk6lc Solution: 1. If nothing can be see in front and side view, long press yellow button for 5 second to shutdowm,then long press button for 4 second into contrast(Now nothing still cann't be see ),then short press the button 20 times to adjust the contrast value to 20. 2.If nothing can be saw in front of mega328 transistor tester, sometimes you could tilt the screen and can see the content . Then you can long press the yellow button into contrast to increase it up to 25. 3.When the brightness contrast digit is less than 15 or over 50, nothing can be read in front of screen, you need to adjust the screen contrast value. The maximum contrast value is digit 63 and then it into the minium value. You can press the yellow button to increase it up to the best brightness contrast value 25. 4. Please contact our customer service if have any question about screen contrast. Function: 1.Automatic detection of NPN and PNP transistors, N -channel and P-channel MOSFET, diodes (including dual diode), thyristors, transistors, resistors and capacitors and other components 2.Automatic test out the pin element and displayed on the LCD 3.Can be detected to determine the transistor emitter forward bias voltage of the transistor, MOSFET protection diode and the amplification factor of the base 4.Measure the gate threshold voltage and gate capacitance of the MOSFET 5.1602 lcd display uses LCD (12864 LCD with backlight) 6. High test speed, valid component test: 2 seconds (except in the larger capacitor of large capacitance measurement also takes a long time , the measured time of one minute is normal) 7. One button operation , power-on test , get a key 8. Power consumption off mode : less than 20 nA of 10. Auto power off function to avoid unnecessary waste, saving battery
