SMART-PULP
CALIBRAT
2.3.1 The NEW RECIpe menu
NOTE! The pulp type to be calibrated must be
active, i.e. in measurement, when you do the
calibration. The active recipe number must be the
same in the MEASURE and CALIBRAT menus.
NOTE! Since SMART-PULP only measures the fiber
consistency, variations in filler content after
calibration will cause a corresponding error in total
consistency measurement where filler is involved.
It is recommendable to write down the CONFIGUR
and CALIBRAT/NEW RECI values of configured

transmitters, including the P1 and P2 values
calculated by SMART-PULP after execution of the
LABORATO menu. For example, when a faulty
transmitter is replaced the new transmitter can then
be made identical with the old one even before
installation. This will require that force measurement
has been calibrated in the way described in the
DIAGNOSTICS chapter by changing P2 manually.
For example, if you increase the value of P2 by 0.1,
the consistency reading will increase by 0.1% Cs at
every consistency level. In other words, you can
make the required zero correction without other
calibration measures.
