If data is downloaded to a PC, the resultant “CR1000_Table1.dat” file is, for example, 150 kB in size. Is 150 kB necessarily its size on the CR1000? Is there any type of data compression being used?

The CR1000 stores data in a binary format (1s and 0s), which is very compact. Campbell Scientific software, such as LoggerNet, collects the data in this binary format and converts it to a readable format such as ASCII. The CR1000 Status table contains information regarding how memory is allocated for data storage. This information can be accessed through the Station Status button on the LoggerNet Connect screen. The Table Fill Times tab lists the tables in the datalogger, along with the number of records in the table.
