Pump Data
The main features of the pump data dialog are listed in the table below. The pump section later in this document provides further details of the Graph Options, the Pump Data Menu options and the options for opening the Pump Database, adding a pump to the Pump Database, Import of a Curve Image and creating a Pump Data Sheet.
