Working in the Status\History Menu
The
Stat\History
menu displays the current analyzer status and historical
information.
To view the
Stat\History
menu, press
until
Stat\History
appears. To view
the sub-menu items within this menu, press
. This menu is not password-pro-
tected because these sub-menu items are for information purposes only and
cannot be changed, with the exception of the
En\Dis Alrm?
and
Clear Alarm?
functions. These functions can be used at the discretion of the operator.
While working from in the
Stat\History
menu, the following rules apply:
• All history buffers are numerically arranged, where ‘
1
’ = most recent entry
and ‘
9
’ being the oldest entry. To view the entries within any of the history
buffers, use the ‘
+
’ or ‘
–
’ buttons.
• Since all history buffer entries are stored in SRAM, the buffers will be
cleared when the analyzer power is off or the analyzer is reset.
• The HCDP buffer (and WDP and WCT buffers, if an external water signal is
provided) is updated at the beginning of each measuring cycle, while the
SCode buffers are updated whenever the code value changes.
• The
basic
(
SCode
) and
extended
(
XSCode
) Status Code entries first display
the total sum of all primary code numbers. The SCode number is then
decoded into its component bits (primary codes), as seen when you press
the ‘
+
’ or ‘
–
’ button. If the decoded status bit is clear (i.e., no alarms are
present) “
OK
” is displayed. Otherwise, the corresponding status message is
displayed. The possible causes of the status bits are described under SCode
and XSCode, in the following descriptions.
Stat\History mode
allows you to view information
only. To change information
(ApplicCFG or MonitorCFG),
a password is required.
