Product description:
This tester has stable performance, can automatically read accurate data, and is easy to use. It is suitable for electronic enthusiasts, electronic developers, designers, and electronic maintenance personnel. The necessary small instruments. It can measure all kinds of resistance, capacitance, inductance, diode, triode, thyristor, MOS field effect transistor; it can judge the device type, the polarity of the pin, the output HFE, the valve voltage, and the junction capacitance of the field effect transistor. It is especially suitable for transistor pairing and identification of mixed surface mount components, and it is also the best partner for amateur DIY.

Main functional parameters
:
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. Support simultaneous measurement and symbol display of two resistances. Both ends of the displayed resistance symbol are the connected tester probe numbers (1-3), and the adjustable potentiometer can also be measured
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@1MHz clock) to 100mF. Resolution up to 1pF (@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~7000uF.
20. The inductance test range is: 0.01mH~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.
Kind tips:
Tear off the screen protector before use for a better display!
Discharge before use! Be sure to discharge the capacitor before the capacitor test, otherwise there will be a danger of burning the machine, and the damage will be at your own risk!
Contrast adjustment method:
After the test result is displayed on the screen, double-click the button to adjust the number displayed in the center of the screen. At this time, single-press the button, the corresponding value will increase, and double-click to save when satisfied. (The reference value is 23-28 is the best)
