-T4 Graphical Multi-function Tester Resistor + Capacitor + Diode + SCR + Inductor + Transistor + MOS Tube The 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 compatible withm an 8.4v battery pack compatible with power supply. Newly added power-on voltage detection function Automatically 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 LCD Can detect the amplification factor and cardinality of transistors, MOSFET protection diodes, etc. to determine the compatible withward bias voltage of the emitter transistor Measure the gate threshold voltage and gate capacitance of MOSFET The display uses 12864 lcd liquid crystal (128 * 64 characters) Higher test speed, effective component test: within 2 seconds (except compatible with 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 done. Power consumption off mode: less than 20 nA Automatic shutdown function can avoid unnecessary waste, save battery energy and improve battery life. Colour:Photo Color Material:plastic Package Contents: 1 x Multifunctional 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.
