Section 2. Quickstart Tutorial
Quickstart tutorial gives a cursory look at CR1000 data acquisition.
2.1 Primer - CR1000 Data Acquisition
Data acquisition with the CR1000 is the result of a step wise procedure
involving the use of electronic sensor technology, the CR1000, a
telecommunications link, and PC datalogger support software.
2.1.1 Components of a Data Acquisition System
CR1000s are only one part of a data acquisition system. To get 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 Sensors
Suitable sensors accurately and precisely transduce environmental change into
measurable electrical properties by outputting a voltage, changing resistance,
outputting pulses, or changing states.

C.2.1.
2.1.1.2 Datalogger
CR1000s can measure almost any sensor with an electrical response.
CR1000s measure electrical signals and convert the measurement to
engineering units, perform calculations and reduce data to statistical values.
Every measurement does not need to be stored. The CR1000 will store data in
memory awaiting transfer to the PC via external storage devices or
telecommunications.
2.1.1.3 Data Retrieval
The main objective of a data acquisition system is to provide data files on a PC.
Data is copied, not moved, from the CR1000 to the PC. Multiple users may
have access to the same CR1000 without compromising data or coordinating
data collection activities.
RS-232 and CS I/O ports are integrated with the CR1000 wiring panel to
facilitate data collection.
