Before starting a ramp test, the values in the “Ramp Test Settings” box will need to be set. The Hold Time is additional
settle time before the ramp begins. The Test Duration controls the speed of the ramp. Press

Graph Settings
The “Graph Settings” box allows the user to select the items that are displayed on the graph. Any items can be shown or
hidden after the data has been downloaded from the positioner.
Monitors
The “Monitors” display box shows information regarding the status of the test. Test Status shows “complete” when the test
is finished. Elapsed Time shows the real time that has passed since the test process started. The Data Acquisition Progress
shows the progress of the test. The 4 buttons between the settings and the graph control how the data is shown.
View Ramp Test
The View Ramp Test button shows all of the signals relative to time on the X axis during the signature test. If a bi-direc-
tional signature has been taken it will show the second signature as if it occurred right after the first.
View Pressure vs. Position
The View Pressure vs. Position button sets up the graph to show the position on the X axis with the corresponding pres-
sures. If a bi-directional signature has been taken it shows both the sets of pressures relative to the valve position.
