General Flow Sensor Critical Use Considerations

• Set up the Graph display to show one of the sensor’s measurements on the

vertical axis. For example, click the “Select Measurement” menu button on

the vertical axis and pick “Diff Press (kPa)” from the menu. “Time (s)”

automatically shows on the horizontal axis.

Zeroing the Sensor

Prior to measurement the sensor should be placed in its operational position,

any fluids to be used should be introduced to the system and hoses should be

restrained. Immediately prior to a data run the unit should be zeroed using the

PASCO Capstone software zero function. Zero drift can occur due to tempera-

ture, position or hose placement changes.

SPARKvue Setup

• When SPARKvue starts up, it shows the Home Screen

for a moment, and then shows a screen that lists the

parameters for the General Flow Sensor, such as “Diff

Press” in “psi”, “Pa”, and “in of Hg”.

• Select a parameter to display on a graph. For example,

touch “Diff Press psi” and then touch “Show. A graph

display of Diff Press (psi) versus Time (s) opens.

• Touch the Start ( ) button to begin recording data.

• Touch the Stop ( ) button to end data recording.

SETUP: For more information on setting up the data

acquisition software and recording data, refer to the

User’s Guide and the online help for the software.
