The setting you use is dependent to your formula. Find the correct setting for your formula here
Every formula is individually tested to ensure the machine dispenses a bottle that matches the water to formula ratio specified on the packaging.
The Formula Pro Advanced will never dispense less formula than the manufacturer specified ratio, but may dispense up to 1g more to allow for settling of the formula in the powder container.
The Formula Pro Advanced has been calibrated so that once the setting you need for your particular formula is entered into the machine it knows exactly how much formula to dispense whether you select 2oz or 10oz of water. You DO NOT need to amend the formula setting if you increase the amount of formula you wish to feed your baby.
You only need to amend the formula setting when you change the formula you are feeding your baby (e.g moving from Infant to Follow on Milk, or changing formula brand)
If your Formula hasn't been tested you can follow the steps here and get in touch with Customer Support who can assist you further.
