Digital Transistor SMD Components Tester Diode Triode Capacitance Inductance Meter

Description: 
The instrument is a small electronic enthusiasts, developers, electronic maintenance and production plant research and development of small instruments. Can be measured in-line devices, but also test chip devices, can be measured a variety of diodes, transistors, MOS tube; can determine the device type, the polarity of the pin, the output HFE, valve voltage, the junction capacitance of the FET, measurable capacitance and resistance. 

Features: 
1. Two key operation, automatic shutdown. 
2. A key operation, boot test, a key to get. 
3. Automatically test the pin element and display them on the LCD. 
4.1602 LCD screen with LCD (12864 LCD backlight). 
5. Test speed, active ingredient test: 2 seconds (in addition to the larger capacitor capacitance measurement also takes a long time, the measurement time is one minute is normal). 
6. Only 20na off current. 
7. Automatic detection of NPN, PNP bipolar transistors, N-channel and P-channel MOS field-effect transistors, junction type FET, diodes, diodes, thyristors, low power unidirectional and bidirectional thyristors. 
8. Automatic identification element pin arrangement. 
9. Bipolar transistor current amplification factor and base-emitter threshold voltage measurement. 
10. Identify the Darlington transistor by the base emitter threshold voltage and the high current amplification factor. 
11. Detectable bipolar transistors and MOS transistor protection diodes. 
12. Gate MOS FET threshold voltage and gate capacitance measurement. 
13. Two resistors and resistor symbols can be measured simultaneously. The right shows a decimal value of 4. Both sides of the resistor symbol show the number of pins. So you can measure the potentiometer. If the potentiometer wiper does not move to extreme positions, we can distinguish between the middle and the ends of the needle. 
14. Resistive measurement resolution of 0.1Ω, can measure 50MΩ. 
15. Can measure 325pf-100mf capacitor, resolution 1pf. 
16. 2uf More capacitors can measure the equivalent series resistance at the same time. Two can be displayed in decimal values with a resolution of 0.01Ω. 
17. Two diodes can be displayed in the correct order and the diode symbol, and the diode forward voltage is given. 
18. The LED is detected as a diode with a higher forward voltage. The combination of LEDs is identified as two diodes. 
19. Reverse breakdown voltage less than 4.5v zener diode can be identified. 
20. Can measure a single diode reverse capacitance. If the bipolar transistor is connected to the collector and emitter of the base and pin, the collector or emitter junction reverse capacitance can be measured. 
21. Can be connected with a single measurement rectifier bridge.

Instructions: 
1. Press the 'boot / test' can be achieved boot and a test function, multiple tests can be repeated by this key; measured after 20 seconds, no operation automatically shut down. 
2. The instrument provides patch, plug-in and external table three measurement methods, each way 1,2,3 feet are the same correspondence. 
3. The device does not need to distinguish between the order of discipline, the measurement will be completed after the completion of each pin corresponding to the device function. 
4. The instrument printed on the back of the electrolytic capacitor corresponding to the ESR typical reference table, the table is for reference only, please refer to the data published by the manufacturers. 
5. Calibration. 
Short to 1, 2, 3 test points, press the 'boot / test' button, the screen prompts whether to enter the calibration, in 2 seconds by 'power on / test' button to confirm, enter the calibration. 
After the screen prompts to disconnect 1, 2, 3 test points, continue after the break until the end of the prompt calibration. 

Precautions: 
Be sure to discharge the instrument before testing the capacitor, otherwise it may damage the instrument. 
When using the adapter, use an adapter with a DC 9V-12V (including 9V, 12V) voltage range. 
The instrument will not charge the battery, when the battery power is less than 6V, please replace the battery. 
When the capacitor is discharged, it can be discharged without power on. 

Packing Included: 
1 x ESR02PRO Digital Transistor Tester (Battery is not included); 
1 x English User Manual.
