LabPro Tutorial 2: Non Auto-ID Sensor and Selected Events Mode
LabPro will automatically identify newer auto-ID sensors; however, you may have a number
of older sensors that you want to use. These are sensors with a 5-pin round
DIN
plug, which
require a
DIN-BTA
adapter to connect to LabPro. The
DIN-BTA
is a small plug with a
5-pin round
DIN
plug on one side, and a white, flat British Telecom plug on the other. Using
these sensors is not a problem, since only a few extra steps are required to get your data.
This tutorial will show you how to set up any non auto-ID sensor (pH is just an example)
and collect data using the Data Pro program in monitor mode. Additionally, the tutorial will
instruct you on the use of the Selected Events mode of Data Pro. Selected Events mode can
be used with all sensors, not just non-auto-ID sensors.
MATERIALS
Palm OS device
pH Sensor with a
DIN-BTA
adapter.
LabPro interface
A number of liquids in which to measure
Data Pro program
pH (cola or any soft drink, milk, vinegar,
distilled water
window cleaner, etc.)
PROCEDURE
1.
Connect the pH Sensor to the
DIN-BTA
adapter, then plug the adapter into Channel 1.
Use the interface cable to connect the Palm OS device to the LabPro interface. Firmly
press in the cable ends.
2.
Turn on the Palm and start the Data Pro program. If you are on the Main screen, tap
to clear any sensors and default settings. (Or, if you are not on the Main screen,
simply tap Data Pro at the top of screen, and choose New from the pull-down menu.)
You will notice that Data Pro did not recognize your pH Sensor this time. That’s
because you have one of the older, non auto-ID sensors that LabPro cannot detect. It
must be set up manually.
3.
To manually set up the sensor, first tap
. You should see the Setup
screen shown at the right. Here you can change the sensor and units of
measurement. To add a non-auto-ID pH Sensor to Channel 1, tap
.
4.
A list of probes will appear. Use the scroll bar until you reach pH, then
tap pH. By choosing a sensor type, Data Pro loads the default calibration
and data collection rate for that sensor. This manual setup is the same for
all non-auto-ID sensors.
