Click a port on the picture of an interface to manually add a sensor. Press the Back-
space or Delete key on the keyboard to remove the selected sensor from the experi-
ment.
Measurements
The Measurements section of the Setup window lists all of the measurements made
by the selected sensor. A check box next to each measurement name controls whether
that measurement appears in the Data Summary.* Where applicable, the Unit of Mea-
sure field next to each measurement is active, from which units can be selected.
Sensor-specific Constants
For certain sensors, constants can be defined to control how the sensor makes its mea-
surements. When a sensor with user-definable constants is selected, a special tab
appears next to the measurements tab. Click the tab to view and change the constants.
Sample Rate
The sample rate of each sensor connected to a PASPORT interface is set individually.
All sensors connected to a single ScienceWorkshop interface share a sample rate.
Click the arrow buttons ( ) to adjust the sample rate of the selected sensor. Click the
units field to select Hz, seconds, minutes, or hours. When units of Hz are selected, the
sample rate value indicates the number of samples per second. When units of seconds,
minutes, or hours are selected, the sample rate value indicates the time between sam-
ples.
Sensor Sampling Options
The Sensor Sampling Options are available for certain sensors and become active
when one of those sensors is selected.
Setup Buttons
Add Sensor or Instrument
Click the Add Sensor or Instrument button to manually add a sensor or other data-col-
lection instrument. A window will open containing complete lists of PASPORT sen-
sors, ScienceWorkshop analog sensors, ScienceWorkshop digital sensors, and other
data-collection instruments.
When you manually add a PASPORT sensor (that is not physically connected), it is
initially not associated with a port. After you have physically plugged in the sensor,
the manually added sensor icon will automatically associate with the port that the
physical sensor is connected to.
When you click the Add Sensor button to add a ScienceWorkshop sensor, it is associ-
ated with the first available port. To select a specific port, click that port on the picture
of the interface instead of the Add Sensor button.
Setup Timers
Click the Setup Timers button to configure photogates, Smart Pulleys and other
switch-type sensors connected to the computer via a Photogate Port (PS-2123A), Dig-
ital Adapter (PS-2159), or ScienceWorkshop interface.
