New style and high quality Automatic detection of NPN and PNP transistors, n-channel and p-channel MOSFET, diode (including double diode), thyristor, transistor, resistor and capacitor and other components Automatic test the pin of a component, and display on the LCD It can detect the transistor, MOSFET protection diode amplification coefficient and the base to determine the emitter transistor forward biased voltage Measure the gate and gate capacitance of the MOSFET threshold voltage It can simultaneously measure two resistors and resistor symbol is displayed. It can measure a single diode reverse capacitance It can be in the correct order and the diode symbol display two diodes, and gives the diode forward voltage It can measure capacitance of 30pF-100mF, resolution 1pF It can be obtained with a single measurement rectifier bridge connection Notice:Before measuring capacitance , the capacitor must be discharged , otherwise very likely damage the meter One -button operation, automatic shutdown Only 20nA shutdown current Automatic identification components pin arrangement Measuring bipolar transistor current amplification factor and base - emitter threshold voltage Via the base - emitter threshold voltage and high current amplification factor to identify transistors Measuring the gate MOS FET threshold voltage and the gate capacitance Eeverse breakdown voltage is less than 4.5V Zener diode can be identified 128x64 big Backlight LCD display,only 2mA when stand by Test range: Inductors, capacitors , diodes, dual diode , mos, transistor, SCR , the regulator, LED tube , ESR, Resistance,Adjustable potentiometer Resistance:0.1 Ohm resolution, maximum 50M Ohm Capacitor:25pf -100,000 uf Inductors:0.01mh-20H Type:Without Case Colour:Yellow Material:PCB Size:63x71mm Package Contents: 1 * Transistor Tester 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. The measurement allowed error is +/- 1-3cm.
