Transistor Tester, ESR Meter Tester Graphical Resistance Capacitance Checker LCR‑T4 Test Meters for Diode Triode Capacitor Resistor

Added boot voltage detection function, one-key operation, can automatically test the component pins and display them on the LCD Automatic detection of NPN and PNP transistors, N‑channel and P‑channel MOSFETs, diodes (including double diodes), thyristors, triodes, resistors and capacitors The display uses LCD(128 x 64 characters), measuring gate threshold voltage and gate capacitance of MOSFET Can detect the amplification factor and base of transistors, MOSFET protection diodes, etc. to determine the forward bias voltage of the emitter transistor Higher test speed, within 2 seconds of valid component test, (except for larger capacitors, the measurement of large capacitance takes a long time, the 1 minute measurement time is normal)
