3.2.1 Main
Screen
The Main Screen is the default screen for viewing the residual value in digital format. The
residual value appears on the screen in four (4) x 1-inch high digits and a decimal; the
decimal place automatically shifts according to the residual value. The residual oxidant
and units (e.g. mg/l free Cl2) are displayed on this screen in smaller digits under the
residual value, and the current time and date are indicated at the top of the screen. The
software is programmed to automatically return to the main screen after 60 minutes
without user interface, unless the user is viewing the data in graphical format. From the
Main Screen, the user can initiate four selection options: Graphing, Calibration, Set Up, or
Diagnostics. If an error or alarm condition takes place, a warning message will appear
across the lower section of the screen, just above the user interface options.
