5.1 CR800 Datalogger
The CR800 datalogger is one part of a data acquisition system. It is a precision
instrument designed for demanding, low-power measurement applications. CPU,
analog and digital measurements, analog and digital outputs, and memory usage
are controlled by the operating system in conjunction with the user program and
on-board clock. The user program is written in CRBasic, a programming language
that includes data processing and analysis routines and a standard BASIC
instruction set. Campbell Scientific datalogger support software facilitates
program generation, editing, data retrieval, and real-time data monitoring (see
Support Software
(p. 76, p. 382)
).
In addition to the CR800 datalogger, suitable sensors and reliable
telecommunications devices are required to complete a data acquisition system.
