Description
<p>The DC Voltmeter / DC Source combines a high-impedance digital dc voltmeter and a low-current dc source.  The dc Source is designed to supply a user-adjustable reference voltage. The digital display of the dc voltmeter
provides accurate voltage readings.  The module is used mainly in the study of analog-to-digital conversions and of digital-to-analog conversions.
The dc source voltage is adjustable through a ten turn potentiometer. Its value can be read from the voltage display by pressing a push button on the front panel of the module.
The dc voltmeter can be used on one of two ranges selected through a push button. The measured voltage is indicated on a 3½ digit display. The high input impedance of the dc voltmeter allows for a precise reading without disturbing the circuits being tested.
