CR200 Overview
FIGURE OV2-1. 512K on the datalogger label indicates the larger memory.
OV2.2 Measurements, Processing, Data Storage
As a datalogger, the CR200 is programmed to measure the sensors and store
data in its EEPROM memory. Data are retrieved from the CR200 using a
computer and CSI software, e.g. LoggerNet.
A CR20X series datalogger with a spread spectrum radio (e.g. CR206) can also
function as a wireless interface between a sensor and a “master” PakBus
datalogger. In this configuration the CR200 measures the sensors and sends
the data to the master datalogger. Data are retrieved from the master, rather
than the CR20X.
OV2.3 Data Tables
The CR200 can store individual measurements or it may use its processing
capabilities to calculate averages, maxima, minima, etc., on periodic or
conditional intervals. Data are stored in tables such as listed in Table OV2-1.
The values to output are selected when running the program generator or when
writing a datalogger program directly.
