5.5.4 Process calibration procedure
The process calibration procedure can be used to make minor
adjustments to the concentration value. When a process
calibration procedure has been run and has completed, a
Process Calibration (PC) offset is calculated. Subsequently, the
displayed concentration has this offset in concentration
subtracted from the measured sodium concentration.
The following steps describe how to take a sample from the
wet-section for independent tests and adjust the sodium
concentration reading accordingly. If the sodium concentration
is already known, steps 1 and 10 can be omitted.
To ru n a Process Calibration procedure:
1. Obtain a clean sample vessel of suitable size for the
volume of sample required.
At the transmitter:
2. Press the key (below the icon).
The Operator menus are displayed:
3. Press the key to select the Enter Configuration menu
and press the key (below the icon).
The Access Level page is displayed:
4. Use the key to scroll to the Advanced access level
and press the key (below the Select prompt) to enter
the top level Configuration menus.
5. If the Calibrate page is not displayed, use the /
keys to scroll to the Calibrate page:
6. Press the key (below the Select prompt).
– If one or more single-stream wet-sections are
connected, the Calibrate / Sodium 1 (2, 3, 4) page is
displayed:
– If a multi-stream wet-section is connected, the
Calibrate / Sodium Three Stream page is displayed:
Note.
 Process calibrations should be used only to make
minor adjustments to the concentration value. If the
displayed concentration differs significantly from the
expected concentration, perform a Two-Po int
calibration from the Calibrate level – see Section
7.1.1, page 43.
 A process calibration can be carried out only on
single-stream and multi-stream wet-sections with 1
stream enabled.
