Analyzed Page Dynamic Error Band On the analyzed data page the ValveLink software analyzes the data collected from the Dynamic Error Band test and calculates the average, maximum, and minimum dynamic error as well as the dynamic linearity, as percentages. Dynamic error band is the difference in travel for a given opening and closing curve stated in terms of percentage of the travel range. The following define the fields on the analyzed page. Zero Ranged Travel—Current, in mA, that corresponds with a ranged travel of zero. ValveLink establishes a best fit line through the Dynamic Error Band data and projects this to a ranged travel of
