Multi-functional transistor tester for automatic detection of NPN and PNP transistors, N channel, P channel, MOSFET and JFET, diodes, dual diode, thyristor, automatic identification of the transistor pinout. It also can be used for frequency measurement and PWM signal generator.
Features:
Digital LCD display for easy readings, can display measured data and graphics.
Use high performance single chip ATmega328 and using external 8MHz oscillator as the system clock.
Single button operation, support for automatic shutdown to reduce power consumption.
DC 7V~12V voltage input, support battery, the current is less than 20nA when the system is turned off.
Automatically detects NPN and PNP transistors, N channel, P channel, MOSFET and JFET, diodes, dual diode, thyristor, etc.
Support identification pin for test element.
Support current amplification factor for bipolar transistor and the base-emitter turn-on voltage.
Support 2 resistors measurement, show its positive and negative, on-state voltage.
Resistance measurement maximum resolution 0.01Ω, can be measured up to 50MΩ.
Can measure a capacitor, capacitance range 25pf~100mF, resolution is 1pF.
Capacitance less than 25pF can be measured by parallel connection another known capacitor is greater than or equal to 25pF.
Support two diodes to be measured simultaneously and display voltage drop for diode.
Automatically test the pins of a component and show on the display.
Resistance less than 2100 ohm while it's equivalent inductance measuring range from 0.01mH-20H.
Program tape self checking function, Support calibration of multiple parameters.
Can be used as frequency meter and frequency generator: frequency range from 1Hz-2MHz and can output 10-bit PWM signal.
Notice:
Before measuring capacitance, the capacitor must be discharged, otherwise very likely damage the meter.
Be sure to disconnect the power from the circuit board when testing the components on the circuit board, the test equipment have residual voltage is not allowed.
