Lecture And Lab July 2022

ATMEAG328 M328 Transistor Tester

Come join the DARC for July 2022 Lecture and Lab – you will build a  powerful ATMEAG328 M328 Transistor/Component Tester. This will be a fun in-person event at the Dallas Medical Center on the 3rd floor. Plan on attending in-person July 23, 2022 start time is 10am central time. Details below

This is an in-person event and is open to the public you do not need to be a member of the DARC to attend. You will assemble a DIY ATMEAG328 M328 Transistor Tester LCR Diode Capacitance ESR meter PWM Square wave Frequency Signal Generator kit. You will need basic assembly tools, a solder iron and accouterments to complete the kit. There are a total of 18 kits available and each kit cost $20.00usd and come complete with a case and battery. The kits are first come first served and pick up is onsite. This is a really nice tester kit and a great addition to your bench. This will also come in VERY handy for another kit the DARC will be building later this summer – details on that to follow but this tester will be good to have.

Features Include :

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.
