Automatic detection of NPN and PNP transistors, N-channel and P-channel MOSFETs, diodes (including double diodes), thyristors, triodes, resistors and capacitors, etc. The pin of the component is automatically tested and displayed on the LCD Can detect the amplification factor and base of transistors, MOSFET protection diodes, etc. Determine the forward bias voltage of the emitter transistor Higher test speed, valid period for component testing: within 2 seconds (except for larger capacitors, the measurement of capacitors takes a long time, and the measurement time is 1 minute is normal) The automatic shutdown function can avoid unnecessary waste, save battery energy and improve battery life. color:As shown Material:ABS size:63 x 71 mm Package Contents: 1 x Multimeter
