Voltage Detection Unit

Category: ID: 1860

1. new boot voltage detection
2. automatically detect NPN and PNP transistors, n-channel and p-channel MOSFET,
diode (including double diode), thyristor, transistor, resistor and capacitor and other
3. automatic test the pin of a component, and display on the LCD
4. can detect the transistor, MOSFET protection diode amplification coefficient and
the base to determine the emitter transistor forward biased voltage
5. measure the gate and gate capacitance of the MOSFET threshold voltage
6. use 12864 LCD liquid crystal display (128 * 64 characters)
7. high speed test, component test: the validity in 2 seconds (except in larger
capacitor, large capacitance measurement also need a long time, the measured time
is 1 minute is normal)
8. a key operation, the boot test, one-click fix.
9. power consumption shutdown mode: less than 20 nA
10. automatic shutdown function, can avoid unnecessary waste, to save battery
power, improve the battery life.
11.Boot working current is not big, can use the 9 v battery power supply, eliminating
the booster with lithium electricity link,
