LCR-T4 Graphical Multi-function Tester Resistor + Capacitor + Diode + SCR + Inductor + Transistor + MOS TubeThe LCD is a 12864 LCD display with backlight, and the backlight color is generally yellow-green.The power supply is a 9v stacked battery. If the power supply is long-term, 2 lithium batteries can be used to form an 8.4v battery pack for power supply.Newly added power-on voltage detection functionAutomatically detect NPN and PNP transistors, N-channel and P-channel MOSFETs, diodes (including dual diodes), thyristors, triodes, resistors and capacitors and other components,Automatically test the pins of components and display them on the LCDCan detect the amplification factor and cardinality of transistors, MOSFET protection diodes, etc. to determine the forward bias voltage of the emitter transistorMeasure the gate threshold voltage and gate capacitance of MOSFETThe display uses 12864 lcd liquid crystal (128 * 64 characters)Higher test speed, effective component test: within 2 seconds (except for larger capacitors, the measurement of large capacitance also takes a longer time, the measurement time of 1 minute is normal)One-button operation, power-on test, one-button to get it done.Power consumption off mode: less than 20 nAAutomatic shutdown function can avoid unnecessary waste, save battery energy and improve battery life.Colour:Photo ColorMaterial:plasticPackage Contents:1 x Multifunctional tester
