This Component Multi-meter Tester is a DIY kit that tests transistors, resistors, capacitors, diodes, etc.
This unit is a fully-assembled.
It can be powered by an AC-to-DC adapter with 5.5 - 12V or an optional 9V battery connector (included, but requires soldering).
Components can be connected to any of the 3 terminals on the terminal block for testing.
Terminals are numbered 1-3 from left-to-right.
This unit is based off of the ATMEGA328 microcontroller and has been fully tested.
Important: Disconnect battery when not in use to avoid battery drain. This device has a very small standby current and if left sitting for long periods, it will drain the battery.
