8. Grinder Calibration (Espresso Machines): This sub menu allows the engineer
to calibrate the grinder settings (stored in the machines memory) to the type of coffee
beans dispensed and converts gram settings to seconds. This procedure must always
be carried out by the engineer before the Evolution B2C machine is used for the first
time, when the type of beans dispensed is changed, before adjusting the water
compensation or after the grinder mechanism has been removed/repaired.
Important: Before commencing the following procedure, ensure that you have a set
of accurate gram scales and a cup with which to catch the ground coffee. Using the
‘tare’ function, calibrate the empty cup with the gram scales. Ensure that the CoEx®
brewer is removed from the machine, the brewer waste bucket is in position, the bean
container contains beans and the container outlet slide is open. To configure the
Grinder Calibration, proceed as follows:
1. From the Product Configuration menu highlight
Grinder Calibration and press the ↵ (Edit) key to
access the menu screen as shown. This displays
the current calibration setting in seconds, eg 1.6
grams of ground coffee will be dispensed per
second of grinder operation.

that the waste bucket is placed correctly in the
machine to catch dispensed ground coffee.
3. The LCD will now display the menu screen as
shown opposite. Place the calibrated cup under
the grinder outlet and press the START/? key.
The grinder will run and dispense dry ground
