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 datalogger.
operating system
The
operating
system
(also
known
as
"firmware")
is
a
set
of
instructions
that
controls
the
basic
functions
of
the
datalogger
and
enables
the
use
of
user
written
CRBasic
programs.
The
operating
system
is
preloaded
into
the
datalogger
at
the
factory
but
can
be
re-
loaded
or
upgraded
by
you
using
Device

Utility
software.

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 trans-
fer of electric power from the datalogger or a peripheral to another device.
output array
A string of data values output to final-data memory. Output occurs when the data table
output trigger is True.
