WDSS Setup – Choose WDSS Setup from the
Sensors menu to scan for, select, and configure
Wireless Dynamics Sensor Systems. Turn on the
WDSS and note its name. Tap Scan to create a
list of available WDSS devices. The scan may
take 20 to 30 seconds and may have to be
repeated several times to find your particular
WDSS. Once a scan has found your WDSS,
select its name in the list, then tap OK.
Select the check box(es) to enable the sensor(s)
you want to use. Tap OK to complete the setup.
Adjust the data collection parameters by
choosing Data Collection from the Sensors
menu. See
Data-Collection Settings for more
information.
Note: WDSS cannot be set up for remote data
collection using LabQuest. Use Logger Pro on a
computer to set up WDSS for remote use.
•
Change Units – In some cases, you may have the option to display the sensor data in
another set of units. Choose Change Units from the Sensors menu to select a different set
of units. Choosing a new unit will change all existing runs for that sensor to the new unit,
as well as any subsequent runs. If this feature is grayed-out in the menu, then the data for
that particular sensor cannot be displayed in another set of units.
•
Calibrate – Most sensors use a custom factory calibration identified by LabQuest.
However, some sensors do require calibration, and you will use the Calibrate tool
accessible from the Sensors menu. Follow the detailed calibration instructions provided
in the booklet included with the sensor. Booklets are also available online at:

•
Zero – Choose Zero from the Sensors menu to set the current sensor reading to zero. This
adds an offset to the current reading. Not all sensors can be zeroed.
•
Reverse –Some sensors read both positive and negative values. For example, the Dual-
Range Force Sensor reads positive values when pulled, and negative when compressed,
by default. Choose Reverse from the Sensors menu to swap the sign of the readings with
respect to the default settings. Not all sensors can be reversed.
Graph Settings
LabQuest App displays the Graph screen when data
collection begins. From this screen, you can adjust
graph settings during data collection. You can choose
what is plotted, how the graph is scaled, and how the
data is formatted.
