Step Four – Calculate new Total Scale Factor For gallons per minute Note: Factory default Total Scale Factor is 00.3076 Take the Rate Scale Factor from Step three and divide by 60. For example if the Rate Scale factor from Step three is 017.720, the Total Scale Factor is 00.2953 Record the number here _____ and also below in “Step six” part h. For liters per minute Note: Factory default Total Scale Factor is 01.1645 Take the Rate Scale Factor from Step three and divide by 60.
