progress meter.
Exploring the Display and Keypad Buttons
Your Retrotec DM-2A mark II gauge features a touch-sensitive keypad that enables you to
use the gauge as an interface to the fan in use. The gauge is essentially comprised of two user
components—a display window and a set of specialized keypad buttons. The display window
(shown next) provides information on the current test mode and/or setup, and provides data on
device status and measurement values.
Viewing the Display Screen
The display portion of your gauge will provide you with all measurement values and the
current status of your device, test configuration, and test device as well as enable you to perform
configuration changes to the gauge itself. Labels surrounding the display screen indicate the
information that is statically available, while contextual information is displayed on various
display screens.
