With IC holder The display unit adopts 160x128 pixel color display, full-screen characters 8x20, 16-bit color depth, graphic display element symbols Rotary switch control, one-key measurement, automatic shutdown Use 9V laminated battery, you can also use power adapter (DC 6.8-12V), the current of the whole machine is about 30mA, and the current after shutdown is about 20nA Automatic detection of NPN and PNP transistors, field effect transistors, diodes, double diodes, thyristors, thyristors, and automatic identification of transistor lead wires Test NPN and PNP transistor common emitter current amplification factor, base-emitter threshold voltage, turn-off collector-emitter leakage current Pole-pass transistor base-emitter threshold voltage and high current gain identification Darlington transistor Built-in detection power transistor and FET protection diode Test FET gate-source threshold voltage conduction, drain-source conduction resistance, gate-source capacitance At most two measuring resistances, so you can measure the three-pin adjustable resistance. If the adjustable resistance is adjusted to the end, it can only be one measured resistance value The maximum resolution of resistance measurement is 0.01Ω. Can measure up to 50MΩ Capacitance measurement range 25pF-100mF, resolution 1pF Measure the equivalent series resistance (ESR) of capacitors greater than 90nF at the same time. The maximum resolution of the equivalent series resistance is 0.01Ω Capacitors larger than 5000pF also show the rate of decrease after charging, and the capacitance value can reflect the quality factor (Q value) Measure up to two diodes to show their positive and negative, on-state voltage The LED also displays a graphic symbol diode, which has a much higher turn-on v.Find many great new \u0026amp; used options and get the best deals for Gm328 Transistor Tester Pwm Diy Signal Generator Esr Voltage Frequency Meter at the best online prices at Order2india Shopping!
