The circuit incorporates a current limiter which provides overload protection. This allows for continuous maximum current adjustment from approximately 0 to 2A. An overload indicator LED is also incorporated.
A toggle switch allows for selection of displaying either the voltage or current. Readings in the current mode are indicated with a letter “A” illuminated on the display for easy identification of the reading mode.
Two voltage adjustment potentiometers (coarse and fine) are incorporated in order to allow for very accurate output voltage adjustment.
