Display
The main display of the analyzer is an Vacuum Florescent Display with two lines of
40 text characters each. Information is organized in the following manner:
Mode Field: The far left portion of the top line of text displays the name of the
operation mode in which the analyzer is currently operating for more information on
operation modes see Section 6.1.
Message Field: The center portion of the top line of text displays a variety of
informational messages. Warning messages are displayed here as are responses
by the analyzer to queries for operation data about the instrument. During
interactive tasks, such as instrument calibration or certain diagnostic procedures,
the instrument's response messages are also displayed here.
Concentration Field: The far right portion of the top line of text displays the
concentration of the sample gas currently being measured by the analyzer. The
number reported here is the actual concentration of the Sample Gas reported in
whatever units the user selects (See Section 6.4). This number remains unaffected,
regardless of how the ranges of the instrument's analog outputs are configured.
Key Definition Field: The Bottom line of text displays is reserved for defining the
function of the row of keys just below the display. These definitions change
depending on which part of the software menu tree is currently being displayed.
