The CR7 is a precision instrument that is primarily used in multi-parameter research and industrial applications. Each CR7 system is individually configured to meet the specific measurement needs of the customer.

This control module is the base of the measurement system, then the input/output module, data logger enclosure, and I/O cards are added. As measurement needs change from study to study, the CR7 can be adapted by modifying the I/O card configuration.

  1. A practical maximum is to connect one multiplexer per every two control terminals on the data logger. Control terminals can be shared between multiplexers to increase the number of connected multiplexers. Sharing terminals, however, requires more complex wiring and programming. Users who would like to connect more than one multiplexer per every two control terminals are advised to contact a sales or support engineer at Campbell Scientific for assistance.
