Campbell Scientific CR200/CR200X-series Dataloggers - Manual (Page 35)

Section 3. Overview
3.1 CR200(X) Overview
The CR200(X) Datalogger is a precision instrument designed for low-power
measurement applications. CPU, analog inputs, digital outputs, and memory are
controlled by the operating system in conjunction with the user program. 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's datalogger support software facilitates program
generation, editing, data retrieval, and real-time data monitoring (see Support
Software (p. 143)).
FIGURE. Features of a Data Acquisition System (p. 24) illustrates a common
CR200(X)-based data acquisition system.
The CR200(X) 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 CR200(X), sometimes
with the assistance of various peripheral devices, can measure most electronic
sensors. Contact a Campbell Scientific applications engineer if you have
questions about a sensor's compatibility with a CR200(X) datalogger.
The CR200(X) measures analog voltage and pulse signals, representing the
magnitudes numerically. Numeric values are scaled to the unit of measure such
as millivolts and pulses, or in user specified engineering units such as wind
direction and wind speed. Measurements can be processed through calculations
or statistical operations and stored in memory awaiting transfer to a PC via
external storage or telecommunications.
