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.

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
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.
