Appendix A: Battery and Adapter Information
OPERATING POWER REQUIREMENTS
•
The LabPro is designed to operate with four AA alkaline batteries.
•
Factors that affect battery life are the actual time that the LabPro is collecting data and the
amount of current used by connected probes during your experiments.
•
To extend battery life in the classroom we recommend that you use an approved power
adapter.
•
For long-term experiments out of the classroom, you can connect an external 6-Volt lantern
battery to the LabPro. (See Connecting an External 6-Volt Battery on Page 40.)
WHEN TO REPLACE BATTERIES
The four AA batteries should be replaced when the low-battery message is displayed on the Main
screen of DataMate. In addition, you can check the batteries at any time by choosing option
CHECK BATTERY on the DataMate Tools screen.
Note: Save all collected data before removing batteries. All LabPro setup information and all
collected data are lost if the batteries are removed and an optional AC adapter is not connected
to the LabPro.
RECOMMENDED BATTERIES
•
Four 1.5-Volt size AA alkaline batteries. Rechargeable batteries are not recommended.
•
One 6-Volt lantern type. Recommended for long-term experiments performed outside the
classroom that draw large amounts of current (for example, when using the Carbon Dioxide
sensor). See Connecting an External 6-Volt Battery on Page 40 for instructions.
INSTALLING THE AA BATTERIES
•
Holding the LabPro upright, push the latch on the battery cover down with your finger and
pull the cover out.
•
Replace all four AA alkaline batteries. Be sure to position them according to the diagram
inside the battery compartment.
•
Replace the cover.
CONNECTING AN OPTIONAL AC ADAPTER
•
Connect one end of an approved adapter to the external power input connection located on
the bottom left side of the LabPro.
•
Plug the other end of the adapter into an electrical wall outlet.
