• 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.
