This is the second step of the calibration. Once the suspended
solids content of the sample has been measured in the
laboratory, the value can be entered into the transmitter. Note
that this sample must correspond to the last sample collection
step performed, otherwise the calibration may not be correct.
1. To start the Collection Complete procedure from the
Calibration Type screen, use the / keys to select
Collection Complete and press the key (below the Edit
prompt).
The Suspended Solids / New Process screen is displayed:
2. Press the key (below the Edit prompt).
The New Process screen is displayed:
3. To start collection for a new process (when the sensor is
installed for the first time in a new process or when the
calibration needs to be reset) use the
/ keys to
select Yes .
To retain the memory of the previous calibrations (adaptive
calibration to fine tune the existing suspended solids
calibration) select
No .
4. Press the key (below the OK prompt).
5. Press key (below the Next prompt).
The Collection Complete screen is displayed:
This screen displays the turbidity recorded when the
sample was taken (read-only PV field) and a field (TSS) to
enter the suspended solids value measured in the lab.
6. Use the / keys to enter the suspended solids value
(ensure the value entered is in the same units as those
displayed in the screen) and press the
key (below the
Continue prompt) when complete.
A new calibration coefficient based on the value entered,
and the previous values if using adaptive calibration, is
calculated.
The calibration is now complete.
7. Press the key (below the Exit prompt) to return to the
