Glossary 129
plot
A plot is a graphical display of data. Some examples are spectrum, trend, and
time plots.
process (DC) voltage measurement
A single valued measurement taken directly from a DC voltage output. Similar
to a process measurement; however you directly measure the value instead of
entering it with the data collector keypad.
Quickload list
A list of measurement definitions to be loaded into a data collector. Emonitor
builds and saves Quickload lists as load files so that they do not have to be
rebuilt every time before loading into the data collector.
resolution
The accuracy of something based on the number of discrete values used to
define it. One example is the resolution of a spectrum measurement. This
refers to the number of spectral lines that are combined to display the
spectrum data. A higher resolution results in a clearer image due to more
discrete values defining the object.
route
See list.
signature
A signature can be either a time or a spectrum measurement. It is a general
term used for multi-valued data, as opposed to single-valued data such as a
magnitude or a process measurement.
spectral line
A spectral line is an individual discrete frequency in a spectrum measurement.
A spectral line is sometimes called a "bin," a "delta f," a "line," or a "line of
resolution."
spectrum alarm
Also called narrowband alarm. It defines the safe operating boundary for
spectrum data from a piece of equipment.
