Basic Parameters: Display: 160 x 128 TFT Display Note:1. One key to start and test, automatically identify the device type, automatically switch the range, and automatically shut down after the test. 2. The standby current is as small as 20na, and the standby power is negligible for long standby time, and the battery can be used for power supply. 3. Automatically detect PNP and NPN type bipolar transistors, N, P channel MOSFET, JFET, diode, double diode, thyristor thyristor (thyristor), triode, resistor, capacitor, capacitor ESR value. 4. Automatically detect the pin layout and give the label according to the actual sequence. 5. Measure the current amplification factor β of the bipolar transistor, the threshold voltage of the emitter junction, and the ICE leakage current. 6. Darlington transistors can be identified by high threshold voltage and high current amplification factor. 7. For bipolar transistors, MOSFET protection diode detection and forward voltage drop Uf. 8. Measure the threshold voltage Vt and gate capacitance C of the MOSFET. 9. Detect and determine the forward voltage of the emitter transistor and the magnification and base of the transistor and MOSFET protection diode. 10. Supports simultaneous measurement and symbol display of two resistances. Both ends of the displayed resistance symbol are the connected tester probe numbers (1 to 3), and the adjustable potentiometer can also measure 11. The resolution of resistance measurement is 0.1 ohm, and the highest measurement value is 50M ohm. 12. The highest four digits of the capacitance are displayed, and the capacitance value ranges from 25pf (8MHz clock, 50pF at 1MHz clock) to 100mF. Resolution up to 1pF (at 8MHz clock). 13. The equivalent series resistance (ESR) capacitance value of capacitors above 2UF can be measured with a resolution of 0.01 ohms and a two digit value displayed. 14. It is possible to display the symbol of the correct direction for both diodes and to display the forward voltage drop. 15. The LED is detected as a diode, it will flash several times continuously during the test, and the double light emitting diode is detected as a double diode. 16. Zener diodes can be tested, if the reverse breakdown voltage is lower than 4.5V it will show as two diodes. 17. The capacitance value of the reverse of a single diode can be measured. Bipolar transistors can also be measured. At this time, the base and collector or emitter must be connected. 18. Only one measurement is needed to find out the connection of the full bridge. 19. The maximum capacitance test is 1000000uf, and the best test range is 0.2nF to 7000uF. 20. The inductance test range is: 0.01mH to 20H, more than 20H, resistance below 2100 ohms will be recognized as inductance, the measurement result only shows a single inductance, and the inductance value is displayed. 21. The test time is about two seconds, and the measurement time of bulk capacitance and inductance will be extended with the actual value. 22. Automatically shut down, after the test, the test result will always be displayed for about 25 seconds, and then shut down. 23. Be sure to discharge the capacitor before testing the capacitor, otherwise the tester will be burned. 24. Types of power devices and amplifiers, transformers, etc. are not allowed to be tested or cannot be tested..
