One of the great features of LabPro is that it can be powered with batteries rather than using AC electricity. The following tips should help you prolong the life of your batteries when collecting data using LabPro and a calculator or computer.

• Quit the DataMate program when you are finished collecting data with the calculator.
• Make sure the power to the LabPro is turned off before storing it. Do this by removing all sensors from the LabPro, then pressing the Start/Stop button followed by the Quick Set-Up button. Two red flashes and beeps indicate the power is OFF.
• Whenever possible, use the AC Power Supply with sensors that either draw a lot of power or need to be continually powered. These sensors include the CO2 Gas Sensor, Dissolved Oxygen Probe, EKG Sensor, Motion Detector, Flow Rate Sensor, pH Sensor, Dual-Range Force Sensor, Ion-Selective Electrodes, and the Turbidity Sensor. An alternative is to use the External Battery Cable (order code EBC, $6) with a 6-V lantern battery.
• Always exit Logger Pro with the LabPro still attached to the computer.
• Update your Logger Pro software to version 2.1.1. It has better power-saving features than previous versions.
• For long-term storage, remove one battery.
