How to calibrate the flow rate
Set the flow rates of components to adjust for taste profile and for over or under potting.
Built-in algorithms in Brewer controller software corrects brew parameter to customer preferences or to trim variations in flow control components
NOTICE: This operation requires operator hold finger on keypad position for one minute—without lifting it.
1) MEASURE THE FLOW RATE:
It is very important to calibrate a heated brewer, preferably a brewer that has been used for brewing.
-Enter programming mode, scroll left to “OUTPUTS”
-Scroll down to “Left(or)Right Valve Test”
-Place 5 liter/2gal measuring container under empty brew-basket.
One good way to measure is to weigh the test water. Use a scale for at least 5 kg/12lb
-Press To Test the Brew Valve. Æ
!
Keep finger on touchpad for one minute! !!DO NOT STOP!!
It is very important for this test to keep finger in place for the entire minute.
After one minute [1 min.]–calibration dispense will stop automatically.
Measure the results of the flow in the 5-liter measuring container and hold the number.
2) AUTOMATIC Built-in CALIBRATE THE FLOW RATE
-Enter this number, in milliliters, into the calibration slider for the Valve tested in the OUTPUT MENU.
-Use milliliters. If measured in fluid ounces (fl.oz) multiply by 29.57 to convert to milliliters
-After entering the measured volume, exit PROGRAMMING and return to the normal screens
3) MANUAL METHOD Operator input: CALIBRATE THE FLOW RATE
Use the amount measured, in milliliters, divided by programmed value and multiply by the current setting

Obtain programmed volume from “PROGRAM” Menu under “Batch Summary”.
Note—match correct batch number to correct side, if two sided.
By entering the new flow rate number into the brewer, the software automatically corrects the valve flow discrepancy
