To create a Trumpet Graph from a Flow Rate data log, there must be at least 60 minutes of data.  If this criteria is met, a form will be presented to allow the user to select the calculation window (in 60 minute increments), the start time (in 30 minute increments), and an interpolation interval.  The calculation window is the time window over which the calculations for the trumpet graph will be made, beginning at the start time.  The defaults for each of these is 60 minutes, if this is possible.

After selecting the desired calculation window, start time, and interpolation interval, the trumpet graph calculations are performed and the Trumpet Graph form displayed.  The graph contains textual presentation of the Set Rate, Average Rate, %Error, analysis period, and the beginning and ending time.  In addition, the values for the Maximum and Minimum percent error and ml/hr error, based on the Set Rate, for each of the time intervals required by the IEC standard 601-2-24, Part 2, particular requirements for safety of infusion pumps and controllers (2, 5, 11, 19 and 31 minutes).
