The first four lines of the display are for numeric or graphic representation of the measured data.
We refer to those first four lines as data lines.

If numeric, a data line contains the value to the
left, with the parameter description and units to
the right.

If graphic, a data line shows a simple graph of
the data over time.
The choice of which parameter is shown on which data line, as well as whether a data line is
viewed as numeric or graphic, is easily selectable. You’ll see how to make these selections
shortly.

Cleaning
The bottom line of the display contains a row of
fixed function keys. You’ll use these keys to
start and stop the pump, enable and disable
measurement of dew point, and other things.
The function of each of these keys never
changes, and they are always available for
use.
Menu Keys
To the right side of the display is a column of
menu keys. Each of these keys changes
function as needed.
Notice that the bottom key in this column is
different from the rest. The bottom key is used
to cycle the upper keys through the various
menu options. The text on the bottom key
changes to indicate the currently selected
menu option. The text of the upper keys
change based on the functions available in the
menu.
