10.6.1.2. Keyboard
A row of eight keys just below the vacuum florescent display (see Figure 10-20) is the main
method by which the user interacts with the analyzer. As the software is operated, labels appear
on the bottom row of the display directly above each active key, defining the function of that key
as it is relevant for the operation being performed. Pressing a key causes the associated
instruction to be performed by the analyzer.
Note that the keys do not auto-repeat. In circumstances where the same key must be activated
for two consecutive operations, it must be released and re-pressed.
10.6.1.3. Display
The main display of the analyzer is a vacuum fluorescent display with two lines of 40 text
characters each. Information is organized in the following manner (see Figure 10-20):
Mode Field: Displays the name of the analyzer’s current operating mode.
Message Field: Displays a variety of informational messages such as warning messages, operation
data and response messages during interactive tasks.
Concentration Field: Displays the actual concentration of H
2
S in the sample gas currently being
measured by the analyzer. Switches to indicate SO

concentration if/when the instrument is
configured for SO
2
measurement or between H
2
S and SO

when the instrument is in multigas
measurement mode.
Keypad Definition Field: Displays the definitions for the row of keys just below the display. These
definitions dynamic, context sensitive and software driven.
