Calibration
Concordia refers to calibration as the process of adjusting the Xpress to
extract the perfect drink.
The Xpress may require adjustment to perform within specific extraction
parameters using the customer’s choice of beans and settings. For
instructions on how to load a customer-specific drink recipe, see the
Updating Software for Customers with Customer Drink Recipes topic on
page 4-30.
Calibration must be completed in the following order:
1. Pump Pressure (Plumbing System Section)
2. Coffee Powder Dose (Coffee System Section)
3. Espresso Grind (Coffee System Section)
4. Water Volume (Plumbing Section)
5. Milk Volume (Milk System and Refrigeration Unit Section)
6. Flavor Dose (Flavor System Section)
If a customer changes the type of beans they are using, their machine
must be re-calibrated.
Calibration must be done with fresh espresso beans. Stale beans are dry
and brittle and will grind more quickly than fresh beans. Ground espresso
beans should be a bit finer than granulated sugar.
The items in the table below must be calibrated in the order listed.
Step 1: Verify Default Settings
Ground coffee particles should be a bit finer than
granulated sugar
Step 2: Visually Verify During Double Espresso Extraction
