2 Vernier LabPro User’s Manual
Buttons
The three buttons on the top of LabPro are used for the following purposes:
TRANSFER begins transfer of calculator programs or applications (apps) between LabPro and an
attached TI graphing calculator.
QUICK SET-UP clears data stored in LabPro’s memory, then polls all channels for auto-ID sensors
and sets them up to collect data. QUICK SET-UP is used when neither a computer nor a calculator is
attached to LabPro and works only with auto-ID sensors.
START/STOP begins sampling for Quick Set-Up. Sampling continues until the default number of
samples is collected or you press START/STOP again. This button also acts as a manual trigger for
certain data-collection modes.
Lights
LabPro has three lights that indicate the LabPro status:
Red indicates an error condition.
Yellow indicates that LabPro is ready to collect data samples.
Green indicates LabPro is collecting data.
Beeps
LabPro has a piezo speaker that makes four kinds of sounds or “beeps.” Appendix B contains a complete
description of the conditions that cause these sounds.
A “good” beep is a medium tone followed by a high tone.
A “caution” beep is a medium tone followed by another medium tone.
A “bad” beep is a medium tone followed by a low tone.
A “tick” sound is made when a key is pressed.
Providing Power to LabPro
Batteries or AC power can power LabPro. To use LabPro with batteries, remove the battery
compartment cover from the underside of the interface. Insert four AA batteries and replace the
compartment cover. To use LabPro with the AC power supply, plug the round plug on the 6-volt power
supply into the side of the interface. Shortly after inserting four AA batteries or plugging the power
supply into the outlet, the interface will run through a self-test. You will hear a series of beeps and
blinking lights (red, yellow, then green) indicating a successful power up. If the self-test is not
successful, make sure that the batteries are installed correctly, and that they are still useable.
Connecting Sensors
Sensors can be divided into two basic types—analog and digital. Examples of analog sensors are
Temperature Probes, pH Sensors, Force Sensors, and Oxygen Gas Sensors. Up to four analog sensors can
be connected to LabPro. Four jacks for the analog sensors (CH1-CH4) are located on the same side as the
AC Adapter Port. The analog ports accept British Telecom-style plugs with a right-hand connector.
Examples of digital sensors are Motion Detectors, Radiation Monitors, Photogates, and Rotary Motion
Sensors. Up to two digital sensors can be connected to LabPro. The digital ports (DIG/SONIC), which
accept British Telecom-style plugs with a left-hand connector, are located on the same side as the serial
and USB computer connections.
Connect the sensor to the appropriate port. An important feature of LabPro is its ability to detect auto-ID
sensors, and automatically set up an experiment. If you are not using sensors with the auto-ID ability, you
can easily set them up with the experiments provided with the Logger Pro
®
software.
