Calibrating the Precision Fill

Calibration

Your Precision Fill was calibrated during production, however we recommend re-calibrating your machine to account for possible changes in regional electrical supply, or any shifting of components during shipping. 

To perform a re-calibration you’ll need the following:

  • An accurate, electronic scale that can read up to 2kg (4.5lb~)
  • A bucket, able to hold around 2kg of coffee (4.5lb~)
  • Ensure the Precision Fill is level, and stable with all 4 feet on the ground.
From the home screen, in the lower left corner click System Settings, and if needed enter the system password (‘0’ by default). Click ‘1. Calibration’, and then click ‘2. Material Clb’ on the left side menu. You’ll be greeted with a screen like this. 
    1. If your readout displays ‘OFL’, please check you’ve removed the shipping brackets. You can follow the Precision Fill / Precision Fill Mini Uncrate and Assembly guide for this step.

If your machine reads ADOFL, please contact support.




  • Place your bucket underneath the discharge chute, and click ‘Fast’ and ‘Discharge’ on the right side to ensure the machine is empty.
  • Click Fast and Discharge again to make sure the discharge gate inside the machine is closed and the Fast Feed is turned off.
  • Wait for the read-out (where it says 0g) to stabilize, and then press ‘Zero Clb’ to set the zero calibration, and wait for it to complete.
  • Place the bucket onto the scale, tare, and weigh out 2000g of coffee into the bucket.
  • Load your 2000g into the machine, and press ‘Fast’, and wait for all of the coffee to enter the weighing chamber.
  • Wait for the read-out to stabilize and click the ‘Record Wt’ button.
  • In the ‘Clb Wt’ white box (underneath ‘Zero Clb’, that shows ‘0’) enter 2000.
  • Click ‘Wt Clb’, the readout should read 2000g. You can now click Discharge to empty the coffee, remember to press Discharge once all the coffee has been discharged.
  • Click Home to go back to the Home Screen.

You have now calibrated your Precision Fill!
