Section 11. Glossary
Term: ohm
The unit of resistance. Symbol is the Greek letter Omega (Ω). 1.0 Ω equals
the ratio of 1.0 volt divided by 1.0 ampere.
Term: Ohm's Law
Describes the relationship of current and resistance to voltage. Voltage equals
the product of current and resistance (V = I • R).
Term: on-line data transfer
Routine transfer of data to a peripheral left on-site. Transfer is controlled by
the program entered in the datalogger.
Term: operating system
The operating system (also known as "firmware") is a set of instructions that
controls the basic functions of the CR800 and enables the use of user written
CRBasic programs. The operating system is preloaded into the CR800 at the
factory but can be re-loaded or upgraded by you using Device Configuration
Utility
(p. 103) software. The most recent CR800 operating system .obj file is
available at www.campbellsci.com/downloads.
Term: output
A loosely applied term. Denotes a) the information carrier generated by an
electronic sensor, b) the transfer of data from variable memory to final-data
memory, or c) the transfer of electric power from the CR800 or a peripheral
to another device.
Term: output array
A string of data values output to final-data memory. Output occurs when the
data table output trigger is True.
Term: output interval
See data output interval
(p. 495).
Term: output processing instructions
See data output processing instructions
(p. 495).
