Numeric Monitor
A digital monitor in data logger support software or in a keyboard/display.
O
offset
A term, often a parameter in a CRBasic measurement instruction, that designates the y-
intercept (aka, shifting factor or zeroing factor) in a linear function. For example, when
converting °C to °F, the equation is °F = °C*1.8 + 32. The factor 32 is the offset.
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.
Ohm's Law
Describes the relationship of current and resistance to voltage. Voltage equals the product
of current and resistance (V = I • R).
on-line data transfer
Routine transfer of data to a peripheral left on-site. Transfer is controlled by the program
entered in the data logger.
operating system
The operating system (also known as "firmware") is a set of instructions that controls the
basic functions of the data logger and enables the use of user written CRBasic programs.
The operating system is preloaded into the data logger at the factory but can be re-loaded
or upgraded by you using Device Configuration Utility software. The most recent data
logger operating system .obj file is available at www.campbellsci.com/downloads.
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 data logger or a peripheral to another device.
