As understood from the previous considerations the model is quite complicated and it is strictly connected to
the firmware developed for this machine; therefore it is kindly suggested not to change the above shown
file. This calibration file has to be used for both 2.5 l and 5 l circuits.
The only value that can be necessary to change is the minimum volume dispensed. If necessary, 0.1 ml can
be replaced with the minimum volume required by the customer formulations.

6.2 Procedure

Calibration primarily represents a sequence of dispensing and weighing operations. Therefore, you must use
a precision scale and actual specific weight values of the colorants in the machine, since the actual
calibration parameters are calculated based on the weight of the amounts dispensed during calibration.
The characteristics of the colorant in relation to the circuit containing it greatly affect the
machine's precision. It is essential TO CALIBRATE ALL OF THE DISPENSING CIRCUITS AT
MACHINE INSTALLATION.
The characteristics of the colorant and of the dispensing circuit involved in calibration,
as well as the environmental working conditions of the machine may affect the result of
calibration.
Calibration results and machine accuracy can be deeply influenced by colorant viscosity,
rheological properties and room temperature where the machine is placed.
After filling the canisters, we recommend leaving the colorant to degas from air for 8-12 hours
before calibrating; during this time it is advisable to increase the automatic stirring frequency so
that the colorants are in ideal condition during calibration.
