1. Automatic detection of NPN and PNP transistors, n-channel and p-channel MOSFET, diode (including double diode), thyristor, transistor, resistor and capacitor and other components2. Automatic test the pin of a component, and display on the LCD3. Can detect the transistor, MOSFET protection diode amplification coefficient and the base to determine the emitter transistor forward biased voltage4. Measure the gate and gate capacitance of the MOSFET threshold voltage5. Use 12864 liquid crystal display with green backlightTest ranges:Inductors, capacitors, diodes, dual diode, transistor, SCR, the regulator, LED tube, ESR, Resistance,Adjustable potentiometerResistance:0.1 ohm resolution, maximum 50M ohmCapacitor:25pf -100,000 ufInductors:0.01mh-20H:ELECTRICALModel Number:LCR-T4AC Current:LCR-T4 ESR Meter Transistor TesterMeasuring Resistance Range:0.1 ohm resolution, maximum 50M ohmOperating Mode:LCR-T4 ESR Meter Transistor TesterMeasuring Inductance Range:LCR-T4 ESR Meter Transistor TesterDisplay Type: Digital DisplayDC Current: LCR-T4 ESR Meter Transistor TesterMeasuring Capacitance Range:25pf -100,000 ufOperating Temperature:LCR-T4 ESR Meter Transistor TesterUsing 9V battery (Not included)Tips:The product may be updated constantly, The Actual Product May Have Slight Differences Or Color Differences the color and appearance may be changed, please don't mind. And take a consideration before place the order if you have request for color or appearance.Notice:1. Before using the device to measure the capacitor, please discharge the capacitor first2. The ESR and Vloss of the capacitor are only displayed when they are valid3. On or Off voltage of the FET must be less than 5VColour:YellowMaterial:PlasticPackage Contents:1 * Transistor TesterOnly 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.
