Single Precision
The degree of numeric accuracy that requires the
use of one computer word. In single precision, seven digits are stored,
and up to seven digits are printed.Contrast
with double precision.
Single-ended
Input
A signal-input circuit where SIG LO (or sometimes SIG HI)
is tied to METER GND. Ground loops are normally not a problem in AC-powered
meters, since METER GND is transformer-isolated from AC GND.
Single-Plane (Static) Balancing Machine
A single plane balancing machine is a gravitational
or centrifugal balancing machine that provides information for accomplishing
single plane balancing.
Slope (Electrode Sensitivity, Span)
See Nernst factor.
Smallest Bending Radius: The smallest radius that a strain gage can
withstand in one direction, without special treatment, without suffering
visible damage.
Software
Generally, programs loaded into a computer from
external mass storage but also extended to include operating systems
and documentation.
Solvation
Ions in solution are normally combined with at least
one molecule of solvent. This phenomenon is termed solvation.
Source Code
A non-executable program written in a high-level
language. A compiler or assembler must translate the source code into
object code (machine language) that the computer can understand and
process.
Span Adjustment
The ability to adjust the gain of a process or strain
meter so that a specified display span in engineering units corresponds
to a specified signal span. For instance, a display span of 200°F
may correspond to the 16 mA span of a 4-20 mA transmitter signal.
Span
The difference between the upper and lower limits
of a range expressed in the same units as the range.
Spare
A connector point reserved for options, specials,
or other configurations. The point is identified by an (E#) for location
on the electrical schematic.
Specific Gravity
The ratio of mass of any material to the mass of
the same volume of pure
cont....
