Starting Logger Pro Software and Preparing to Collect Data

Locate the Logger Pro icon on your computer and double-click on it, or use the Start menu (Windows

computers). An important feature of LabPro is its ability to detect auto-ID sensors, and automatically set

up an experiment

If Logger Pro does not detect your LabPro and/or a sensor is not connected, the Collect button will be

greyed out. Make certain that you have a LabPro connected to a serial or USB port of your computer and

that it has power. Choose Connect Interface from the Experiment menu. The computer will attempt to

communicate with LabPro. If you see the following message

, then Logger Pro is having trouble

communicating with LabPro. Select the correct port or check your current port and click Yes/OK. If this

does not work, consult Appendix A.

If you have connected a Stainless Steel Temperature Probe and the computer has detected the LabPro

interface, for example, you will see the following screen, which shows a graph of Temperature vs. Time

along with the current reading at the top.

Notice how the program automatically identified the temperature probe (an auto-ID sensor). The current

temperature reading is displayed in the status bar at the top of the screen. The default data-collection

mode is time graph. In this example, you have a Temperature Probe, reading in Celsius, and collecting

data as a function of time for 180 seconds. If you now disconnect the Temperature Probe and connect a

different auto-ID sensor, Logger Pro will set up a new experiment file for the new sensor.

You are now ready to collect data. The next section is a tutorial that uses our Stainless Steel Temperature

probe to investigate the response time of the temperature probe.

Logger Pro software contains experiment files for most Vernier lab books.

The dialog boxes and screen displayed are from Logger Pro 3. Logger Pro 2 dialog boxes are different.
