GM328 Multi-use Transistor Tester Diode DIY KITS With IC Block Acrylic Case Tool

Description

Description
JP137401
Production：
Multi-functional transistor tester for automatic detection of NPN and PNP transistors, FET, diodes, dual diode, thyristor, SCR, automatic identification of the transistor pinout. Also can be used as square signal and PWM signal generator. The DIY acrylic DIY case can efficiently protect the tester.
Features:
The use of SCM ATMEAG328P DIP-28. With IC Block
Digital LCD display for easy readings, can display measured data and graphics.
Rotary switch control, a key measurement for convenient use.
Main chip is the DIP, easy for electronic enthusiasts to DIY or update the main chip.
Use 9V battery(not included), can also use DC power(DC 6.8-12V).
Automatic shutdown, shutdown current is only about 20nA.
Automatically detects NPN and PNP transistors, FET, diodes, dual diode, thyristor, SCR, automatic identification of the transistor pinout.
Test NPN and PNP transistor common-emitter current amplification factor, the base-emitter threshold voltage, off the collector - emitter leakage current.
Support 2 resistors measurement, show its positive and negative, on-state voltage.
Resistance measurement maximum resolution 0.01Ω, can be measured up to 50MΩ.
Automatically test the pins of a component and show on the display.
Measure FET gate threshold voltage and gate capacitance.
For the following 2100Ω resistor while measuring its inductance measuring range from 0.01mH - 20H.
Can be used as signal generator and frequency meter: frequency range from 1Hz-2MHz and can generate 1%-99% PWM(pulse width modulation) signals.
Notice:
Before measuring capacitance, the capacitor must be discharged, otherwise very likely damage the
meter.
