Data Pro 37
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 its AC power
adapter whenever possible.
•
There have been significant improvements in the LabPro OS since it was first
released. You can go to
www.vernier.com to update the LabPro OS.
•
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 further in
this document.)
When to Replace Batteries
You can quickly check the status of your AA batteries by choosing About from the Data
Pro menu.
Note: Save all collected data before removing batteries. All LabPro setup information
and all collected data are lost if the batteries are removed and the optional AC adapter is
not connected to the LabPro.
Recommended Batteries For LabPro
•
Four 1.5-Volt size AA alkaline batteries.
•
One 6-Volt lantern type. Note: This is only necessary for long-term experiments
performed outside the classroom that draw large amounts of current (for example,
when using a motion detector). See Connecting an External 6-Volt Battery on the next
page of this manual 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.
