Basic functions: 1. one-button operation, automatic shutdown. 2. shutdown current is only about 20nA. 3. Adopt 8MH crystal. 4. can automatically detect NPN, PNP bipolar transistors, N-channel and P-channel MOS FET, JFET, diodes, dual diode, thyristor small power unidirectional and bidirectional thyristor. 5. automatic identification pin arrangement of components. Current amplification factor and base 6 measuring bipolar transistor - emitter threshold voltage. 7. can be extremely via the base - emitter threshold voltage and high-current amplification factor identification Darlington transistors. 8. protecting diodes can detect bipolar transistors and MOS transistors. 9. measuring MOS FET gate threshold voltage and gate capacitance. 10. can simultaneously measure two resistors and resistor symbol is displayed. 4-digit display with decimal value 11 on the right. Resistance symbol is displayed on both sides of the pin number. So you can measure the potentiometer. If the potentiometer wiper position will not be transferred to a certain extreme, we can distinguish between the middle and both ends of the pins. 11. resistance measurement resolution is 0.1 ohms, 50M ohms can be measured. 12. can measure capacitance. Capacitor symbol is displayed on the right display values can be displayed with a decimal four values. Can measure the capacitance of 30pF-100mF resolution 1pF. 13. 2uF more capacitors can measure the value of the equivalent series resistance ESR. The two values can be displayed with a decimal, resolution 0.01 ohms. 14. Two diodes can be displayed in the correct order and a diode symbol, and gives the diode forward voltage. 15. LED is detected as a diode, a higher forward voltage. Combo of the LED is recognized as two diodes. 16. reverse breakdown voltage is less than 4.5V zener diode can be identified. 17. can measure a single diode reverse capacitance. If the connection base and collector of the bipolar transistor or the emitter of a pin, or the reverse can be measured or the collector junction capacitance of the emitter junction. 18. with a single measurement can get connections rectifier bridge. 19. Although the measurement limit capacitance of 25pF, but you can be measured by the measured capacitance with a known volume of at least 25pF capacitor in parallel, then the measure will result in parallel capacitance obtained by subtracting Specification: Material: electric components Color: multicolor Board Size: 7.8*6.8*0.2cm Package included: 1 x DIY/Mega328 Diode Capacitance ESR Meter
