3.1 CR1000 Overview
The CR1000 Datalogger is a precision instrument designed for demanding
low-power measurement applications. CPU, analog and digital inputs, analog
and digital outputs, and memory are controlled by the operating system in
conjunction with the user program. The user program is written with
CRBASIC, a programming language that includes data processing and analysis
routines as well as a standard BASIC instruction set. Campbell Scientific’s
datalogger support software facilitate program generation, editing, data
retrieval, and real-time data monitoring (see Section 13 Support Software).
FIGURE 3.1-1 illustrates principal features of common CR1000-based data
acquisition systems.
FIGURE 3.1-1. Principal Features of CR1000 Data Acquisition Systems
As a simple concept, the CR1000 is a multimeter with memory and
timekeeping. It is one part of a data acquisition system. To acquire quality
data, suitable sensors and reliable telecommunications devices are also
required.
Sensors transduce phenomena into measurable electrical forms, outputting
voltage, current, resistance, pulses, or state changes. The CR1000, sometimes
with the assistance of various peripheral devices, can measure nearly all
electronic sensors.
