Battery and Adapter Information

Operating Power Requirements
The CBL is designed to operate with four AA alkaline batteries.
Factors that affect battery life are the actual time that the CBL is on and
the amount of current used by connected probes during your
experiments. The display contains a low-battery icon (
know when these batteries should be replaced.
To extend battery life in the classroom we recommend that you use the
approved power adapter.
For extended experiments out of the classroom, when more battery
power is needed, you can connect an external 6-Volt lantern battery to
the CBL .
When to Replace Batteries
The four AA batteries should be replaced at least once each year to
prevent damage from leaking batteries, or when the low-battery icon
%
( ) is displayed—whichever comes first. The low-battery icon is
displayed when the internal battery voltage drops to 4.5 Volts. (Refer to
"Installing the AA Batteries" on page 11.)
Note: Save any collected data before removing batteries. All CBL setup
information and all collected data is lost if the batteries are removed and
the optional AC adapter is not connected to the CBL.
Recommended Batteries
¦
Four 1.5-Volt size AA alkaline batteries.
¦
One 6-Volt lantern type. Recommended for experiments performed
outside the classroom that draw large amounts of current (e.g., when
using a motion detector).
Installing the AA Batteries
1. Holding the CBL upright, push the latch on the battery cover down
with your finger and pull the cover out.
2. Replace all four AA alkaline batteries. Be sure to position them
according to the diagram inside the battery compartment.
3. Replace the cover, and then press P to turn the CBL on.
