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-protected 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.
