One click operation, automatically turning off the power. 2. The shutdown current is only 20nA and supports battery operation. 3. Automatic detection of PNP and NPN bipolar transistors, N, P channel MOSFETs, JFETs, diodes, dual diodes, thyristor thyristors. 4. Automatically detect pin layout. 5. Measure the current amplification coefficient and threshold voltage of the emission junction of a bipolar transistor. 6. Darlington transistors can be identified by high threshold voltage and high current amplification coefficient. 7. Detection of protective diodes for bipolar transistors and MOSFETs. 8. Measure the threshold voltage and gate capacitance value of MOSFETs. 9. Supports the measurement and symbol display of two resistors, with up to four digits and units displayed. The displayed resistance symbol shows the connected tester probe numbers (1-3) at both ends. So Potentiometer can also measure. If the Potentiometer is adjusted to one end of it, the tester cannot distinguish between the pins in the middle and at both ends. 10. The resolution of resistance measurement is 0.1 ohms, with a maximum measurement value of 50M ohms. 11. A capacitor can be detected and measured. Display the highest four digits and units. The value can range from 25pf to 100mF. Resolution up to 1 pF 12. It is possible to measure the Equivalent series resistance (ESR) capacitance of capacitors with a value above 10UF. The resolution is 0.01 ohms and displays two digit values. 13. It is possible to display symbols in the correct direction for two diodes. In addition, the positive voltage drop is displayed. 14. The LED is detected as a diode, and the forward voltage drop is much higher than Normal height. Double light-emitting diodes are detected as double diodes. 15. Zener diodes can be detected if the reverse breakdown voltage is below 4.5V. This will be displayed as two diodes, which can only be determined by voltage. The symbols around the diode of the probe are the same, in this case, you can identify the true anode of the diode by the threshold voltage near 700mV! If there are more than 3 diode type parts detected, establish the number of diodes and display another failed message. This will only occur if the diode is connected to all three probes and at least one is a type diode. In this case, you should only connect two probes and initiate the measurement again, one after the other. 16. Measure the capacitance value of a single diode in the opposite direction. Bipolar transistors can also be measured if you connect the base to the collector or emitter. 17. Only one measurement is needed to find the connection of the entire bridge. 18. Capacitors with values below 25pf are usually undetectable, but can be connected in parallel with a diode or at least 25pf capacitor. In this case, you must subtract the part of the parallel capacitance value. 19. A resistance below 2100 ohms will measure inductance. The range will exceed 20H from 0:01mH, but the accuracy is not good. The measurement results only show a single component connection. _x000D_
