Campbell Scientific CR200/CR200X-series Dataloggers - Manual (Page 15)

Section 2. Quickstart Tutorial
Quickstart tutorial gives a cursory look at CR200(X) data acquisition.
2.1 Primer - CR200(X) Data Acquisition
Data acquisition with the CR200(X) is the result of a step wise procedure
involving the use of electronic sensor technology, the CR200(X), a
telecommunications link, and PC datalogger support software.
2.1.1 Components of a Data Acquisition System
A typical data acquisition system is conceptualized in FIGURE. Data
Acquisition System Components (p. 3). A CR200(X) is only one part of a data
acquisition system. To acquire good data, suitable sensors and a reliable data
retrieval method are required. A failure in any part of the system can lead to
"bad" data or no data.
2.1.1.1 How Programmed Instructions Are Evaluated
The CR200(X) evaluates programmed instructions sequentially.

2.1.1.2 Sensors
Suitable sensors accurately and precisely transduce environmental change into
measurable electrical properties by outputting a voltage, changing resistance,
outputting pulses, or changing states.
