Automatic detection of NPN and PNP transistors, n-channel and p-channel MOSFET, diode (including double diode), thyristor, transistor, resistor and capacitor and other componentsAutomatic test the pin of a component, and display on the LCDIt can detect the transistor, MOSFET protection diode amplification coefficient and the base to determine the emitter transistor forward biased voltageMeasure the gate and gate capacitance of the MOSFET threshold voltageIt can simultaneously measure two resistors and resistor symbol is displayed. It can measure a single diode reverse capacitanceIt can be in the correct order and the diode symbol display two diodes, and gives the diode forward voltageIt can measure capacitance of 30pF-100mF, resolution 1pFIt can be obtained with a single measurement rectifier bridge connectionNotice:Before measuring capacitance , the capacitor must be discharged , otherwise very likely damage the meterOne -button operation, automatic shutdownOnly 20nA shutdown currentAutomatic identification components pin arrangementMeasuring bipolar transistor current amplification factor and base - emitter threshold voltageVia the base - emitter threshold voltage and high current amplification factor to identify transistorsMeasuring the gate MOS FET threshold voltage and the gate capacitanceEeverse breakdown voltage is less than 4.5V Zener diode can be identified128x64 big Backlight LCD display,only 2mA when stand byTest range:Inductors, capacitors , diodes, dual diode , mos, transistor, SCR , the regulator, LED tube , ESR, Resistance,Adjustable potentiometerResistance:0.1 Ohm resolution, maximum 50M OhmCapacitor:25pf -100,000 ufInductors:0.01mh-20HProtection Case:This case is a protective fitting for LCR-T4 transistor inductor capacitor ESR meter multifunction tester.Type:With CaseColour:YellowMaterial:PCBSize:63x71mm Package Contents:1 * Transistor Tester1 * Acrylic shell Only the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
