Data Pro 20
THE SETUP OPTION
Sensors
Note: When connecting sensors to analog channels, you should use the channels in numerical
order. In other words, connect the first sensor to Channel 1 (CH1), the second sensor to
Channel 2 (CH2), and the third sensor to Channel 3 (CH3). If you are using only one sensor,
it should be connected to Channel 1.
•
If the sensor is auto-ID, the channel number and sensor type is automatically displayed
on the main screen. If necessary, change the data collection mode as described in the
following section titled Data Collection Modes. Otherwise, you are ready to collect data.
•
If the sensor is not auto-ID, follow the steps below to tell LabPro that the
sensor is connected. On the Data Pro main screen, tap
.
To add a non-auto-ID sensor, tap the channel to be set up.
A list of sensors will appear.
Select a sensor or use the scroll bar to scroll the list of sensors.
Once you have selected the sensor you want to use, tap . You will be returned to the
main screen.
Data Pro contains default time graph settings for each sensor. You can change the window in
which the collected data is graphed, and you can change the type of triggering used in the
experiment.
Data Collection Modes
For each Vernier sensor, Data Pro loads a default experiment appropriate for
the sensor. The default data collection mode for all sensors is Time Graph
(collecting data points at a predetermined rate for the appropriate sensor). To
choose another mode, or to change the time graph data collection parameters,
tap
from the main screen, then tap from the setup
screen. The mode button displays the current mode.
