Process Calibration
Performs a process calibration. This calibration can be used to adjust
the concentration value on the wet-section to a value that has been
determined in the laboratory. It should only be used to make minor
adjustments to the reading.
A large discrepancy between the lab and wet-section readings could
be due to errors in calibration solutions or indicate problems with the
wet-section.
A
Process Calibration
can not be initiated on a multi-stream transmitter
unless one stream only is enabled.
Note
: There is no recovery period after a process calibration.
Grab Sample
Performs a Grab Sample routine. The
Grab Sample
function can be
used to measure the sodium concentration of an external sample, for
example, from another point in the process.
Note
: During a grab sample routine the sample connected to the
wet-section is directed to drain via the sample stream valve.
Scheduled Calibration
Type
Selects the type of scheduled calibration.
Off
Low Standard Cal.
High Standard Cal.
Two-Point Cal.
Regeneration Cycle
Frequency
Selects the scheduled calibration frequency.

Daily
Weekly
Selectable options:
Daily, 2, 3, 4, 5, 6, 7
days.
Selectable options:
Weekly, 2, 3, 4, 5, 6, 7, 8
weeks.
Interval
Selects the scheduled calibration interval.
Time of Next Cal.
Selects the time and date of the next and subsequent scheduled
calibrations.
Scheduled calibrations are not performed until the date / time set is
reached. The date of the next scheduled calibration is updated
automatically according to the frequency set. For example, if
Frequency
is
5
days and
Time of Next Cal
. is
12:00:00 2013-01-05
, it
is updated automatically to:
12:00:00 2013-01-10
.
Note
: If the scheduled calibration cannot be run, or is not successful,
the next scheduled calibration date is updated according to the
Frequency
set and a
Missed Scheduled Cal
. diagnostic message is
created. Parameters are not enabled if
Frequency
is
Off
