Measurement of bipolar transistor current amplification factor and base-emitter threshold voltage. Automatic component pin test and display on LCD backlight 128*64. Measure gate and threshold voltage capacitance of MOSFET. One-button control,automatic shutdown,shutdown current only 20nA./ The breakdown voltage is less than 4.5V,the Zener diode can be identified. More than 2uF capacitors can simultaneously measure equivalent series resistance ESR values. Through base-emitter threshold voltage and high current amplification factor to identify Darlington transistors. Can measure two resistors simultaneously,and the resistor symbol is displayed. Displayed on the right with a decimal value of 4. Can detect the transistor,the amplification coefficient of the MOSFET protection diode and the base to determine the bias voltage downstream of the emitter transistor. Automatic detection of NPN and PNP transistors,n-channel and p-channel MOSFET,diode,thyristor,transistor,resistor ,capacitor and other components. Features: Material: PCB Power mode: 6F22 Display: 128*64 LCD backlight Test speed: 2 seconds (1 minute is normal for a large capacitor) Stop current: 20nA Displayed value: 25pf-100mF (1pF resolution) Inductance: 0.01mH-20H Resistance: 2100 Power Volatge: 9V layered battery / 2 li-ion batteries to form a 8.4V battery pack Resistance measurement resolution: 0.1 ohms Highest measured value: 50M ohm Provided test current: approx 6mA Product size: 7.2 * 6.25cm (L * W) Orange color Quantity sold: 1 piece Function Added power-on voltage detection function Automatic detection of NPN transistors and PNP,N-channel and P-channel MOSFETs,diodes (including dual diodes),thyristors,triodes,resistors and capacitors,etc. The component pin is automatically tested and displayed on LCD Can detect amplification factor and base of transistors,MOSFET protection diodes,etc. Determine the forward bias voltage of the emitter transistor MOSFET measuring gate threshold voltage and gate capacitance The display uses 12864 liquid crystal lcd (128*64 characters) Higher test speed,component test valid period: within 2 seconds (except for larger capacitors,large capacitance measurement also takes a long time,measurement time is 1 minute is normal) One-key operation,start-up test,one-key to get it. Power consumption in shutdown mode: less than 20nA The auto-off function can avoid unnecessary waste,save battery power and improve battery life. About the chromatic aberration: The goods sold are all taken in kind,but due to different lighting,monitors,etc.there will be a little color difference,which is u This is a normal phenomenon,not a quality problem About the size: The dimensions of the products sold are all measured manually. Due to different measurement methods and tools,there may be an error of 1-2mm,which is normal
