Standby current is only 20naÂ£Â¬ the standby time is long.Â£Â» 9.Support late automatic calibrationÂ£Â¬ and ensure the accuracy. 10. Single button operationÂ£Â¬ quick and convenient. Main Function:(New add function: Boot automatic detection function) 1. One key to bootÂ£Â¬ one key testÂ£Â¬ automatic recognition device typeÂ£Â¬ automatic switching rangeÂ£Â¬ automatically shut down after the test. 2. Shutdown standby current minimum is only 20naÂ£Â¬ ultra long standbyÂ£Â¬ the standby power consumption can be ignoredÂ£Â¬ and can be used in battery powered. 3. Automatic detecting the PNP and NPN type bipolar transistorÂ£Â¬ NÂ£Â¬ P channel MOSEFTÂ£Â¬ JEFTÂ£Â¬ two level pipeÂ£Â¬ dual two stage tubeÂ£Â¬ thyristor SCR (SCR)Â£Â¬ three tubesÂ£Â¬ resistorsÂ£Â¬ capacitors (electric discharge must be done first before measurement of capacitance)Â£Â¬ the capacitance ESR value 4. Automatic detect pin layout and given a label according to the actual sequence. 5. The threshold voltage and current measurement of bipolar transistor amplifying coefficient and the emitter junction leakage currentÂ£Â¬ ICE. 6 Darlington transistor can be through the high threshold voltage and high current amplification factor identification. 7. The bipolar transistorÂ£Â¬ MOSFET protection and detection two tubes and the forward voltage drop Uf. 8. To detect threshold voltage VT of MOSFET and measure the gate capacitance value C. 9. Detection and transistor and MOSFET protection class two tube magnification and the determination of the base dataÂ£Â¬ to confirm emitter transistor the forward voltage 10. Support two resistance measurement at same time and symbol displayÂ£Â¬ a maximum of four digit display. The display of resistance symbol two end is the tester probe number connection (1-3). So the adjustable potentiometer can also be measured (if the potentiometer to adjust to its endÂ£Â¬ the tester can not distinguish the middle and both ends of the pin) 11. The resistance measurement resolution is 0.1 ohmsÂ£Â¬ the highest measurement value is 50M ohms. 12. The highest four digit display-capacitor capacitance value range from 25pf (clock 8M Hz clockÂ£Â¬ 50pf@1MHz) to 100mF. The resolution can reach 1pF (@8MHz clock). 13 Measure the capacitance the capacitor equivalent series resistance of the 2UF numerical above (ESR) Â£Â¬the resolution is 0.01 ohms and display two digit numerical. 14. Display right direction signs of two two level Â£Â¬ and display the forward voltage drop. 15. LED detection is two level pipeÂ£Â¬ flashes continuously several times during the testingÂ£Â¬ double emitting two tubes detected as the double diode. 16. It can test the zener diodeÂ£Â¬ if the reverse breakdown voltage is lower than 4.5V it shows two pieces diodesÂ£Â¬ and it can be confirmed by the voltage. The probe around the diode symbol is the sameÂ£Â¬in this caseÂ£Â¬ you can identify the diode true anode by the threshold voltage at 700mV more or less! 17.It can measure the single diode reverse capacitance values. Bipolar transistor also can be measuredÂ£Â¬ and then must be connected with the base and collector or emitter. 18.The connection of the whole bridgerequires can be measured only one time. 19. The maximum of capacitor test is 1000000ufÂ£Â¬ the best testing range is 0.2nF~7000uFÂ£Â¬ if the test value is below the 25pf capacitorÂ£Â¬ and a diode in parallel manner or at least 25pf shunt capacitor. After get the measured resultsÂ£Â¬ then use it to minus parallel capacitor solute. 20. The inductance test range: 0.01mH~20HÂ£Â¬ more than 20HÂ£Â¬ less than 2100 ohm resistance could be identified as inductanceÂ£Â¬ the measurement results show only a single inductorÂ£Â¬ and display the inductance value. 21. The test time is about two secondsÂ£Â¬ large capacitance and inductance measurement time will be extended as the actual value. 22. Automatic shutdownÂ£Â¬ after the test it has been show test results about 3 secondsÂ£Â¬ then shut down. 23. It can be extended fixture after testing deviceÂ£Â¬ this fixture needs self DIY or purchase it.
