Overview

The CR1000M-4M was offered when the standard CR1000M had 2 Mbytes of data/program storage. In September 2007, the standard CR1000M started having 4 Mbytes of memory, making the CR1000M-4M obsolete. The CR1000M-4M needed to be connected to a CR1000WP to function as a complete CR1000-4M datalogger.
