M328 Diode Triode Capacitor Resistor Transistor Tester ESR Meter Multi-Function Tester with Test Board

Description This is a kind of fine quality transistor tester one button operation automatically turn off the power increase the power switch avoids battery power consumption during storage and shutdown Automatic detection of PNP and NPN bipolar transistors N P channel MOSFETs JFETs diodes dual diodes thyristors thyristors resistors capacitors inductors Automatically detect pin definitions You can have a try Features 1 Turn on the tester s power switch the LCD will not light up press the test button TEST button and the LCD will light up 2 If testing devices with high capacitance inductance and high voltage drop it is recommended to test the test interface of the tester 3 Try not to use the test line to avoids large errors caused by the resistance of the test line itself 4 The tester is not suitable for applications with high measurement accuracy 5 Measureable components various diodes capacitors resistors triodes thyristors MOS tubes etc 6 It is only used to measure electronic devices and cannot be used to test power devices high power mos thyristors etc 7 The instrument has been calibrated at the factory users do not need to calibrate themselves can be used directly 8 Built in 3 7V lithium battery 12864 graphic LCD display test results 9 One button operation automatically turn off the power increase the power switch avoids battery power consumption during storage and shutdown 10 Automatic detection of PNP and NPN bipolar transisto
