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 buers are numerically arranged, where ‘1’ = most recent entry
and ‘9’ being the oldest entry. To view the entries within any of the history
buers, use the ‘+’ or ‘–’ buttons.
• Since all history buer entries are stored in SRAM, the buers will be
cleared when the analyzer power is o or the analyzer is reset.
• The HCDP buer (and WDP and WCT buers, if an external water signal is
provided) is updated at the beginning of each measuring cycle, while the
SCode buers are updated whenever the code value changes.
• The basic (SCode) and extended (XSCode) Status Code entries rst 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.
