If unit has been idle (no shots taken for over a half hour) take one shot of size
Medium (coffee) for each product to exercise the tubes.
Place a cup on the external scale and press tare.
Place the cup under the proper product tube.
Select the product to be dispensed and then press the "M" button to dispense
product amount for a medium coffee.
Weigh the product on the external scale.
If the shot weight is within the specified range listed in the Redbook (41-51 g)
then you can move on to the next product. If the shot weight is outside of the
specified range then a simple calibration is required. To calibrate the unit, follow
Steps 7 to 11.
Repeat Steps 2 and 3, then go to the Calibration menu by pressing the Down
arrow once, the display will read Calibrate Disp Select Product.
Press the button of the product you wish to calibrate (Milk, Cream or Skim) and
then press the M button. NOTE: make sure the cup is under the valve at this
time, because a medium sized shot is dispensed.
Weigh the cup on the external scale.
The display now reads "Enter Weight 46 Grams". Press the Up or Down arrow
until the value on the display matches the weight that you measured using the
external scale and then press select.
The display again reads "Calibrate Disp Select Product". You may now select the
next product to calibrate or press the Home button to return to normal operation.
