    The CBL 2™ is designed to operate with four AA (LR6) alkaline batteries. Factors that affect battery life are the actual time that the CBL 2 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.

  • Page 98: Installing The Aa (Lr6) Batteries

    The Texas Instruments model AC-9920 power supply is an AC-to-DC power adapter approved for use with the CBL 2. The model AC-9201 power supply can also be used with the CBL 2. Use of other power adapters may result in RF interference and/or unacceptable performance.

    CBL 2™ Error Messages Error messages that may occur when using the CBL 2 system without the DataMate program are listed in the table below. To retrieve an error message, use Command 7 listed in Appendix B. In almost all cases, an error result will cause the unit to sound the “low tone” two or more times and illuminate the red LED two or more times.

  • Page 107 Archive operations must occur only when the unit is idle. This error indicates an attempt to use a channel that does not exist on CBL 2™ (for example, channel 42). This error indicates an undefined error has occurred. This error indicates that the current load on the analog or digital ports is more than can be supplied by the unit and the power has been turned off to prevent damage.
