calculates and stores an average and standard deviation of these
samples.
SCALE FACTOR
A number that is used as a multiplier to convert raw data from the
SymphoniePLUS3 logger to useful units of measure (such as °F, or
m/s). The scale factor is often called the “slope” or “transfer
function”. For example, the scale factor for the NRG 40C
Anemometer is 0.765 m/s per Hz.
SHELTER BOX
The lockable steel enclosure that mounts to a tower or structure
and protects a logger from weather and vandalism.
SCM
Signal Conditioning Module. An optional plug in module that
provides the electronics to configure the input on channels 4-6
and 9-12 on the SymphoniePLUS3 logger for a particular sensor.
The SCM also tells the logger whether the sensor is a counter
(frequency output), totalizer, vane or linear signal.
SITE
The installation location of the SymphoniePLUS3 logger,
TallTower, and sensors. A site is a unique and permanent location.
SymphoniePLUS3 loggers store a site number you assign to
identify the site.
STANDARD DEVIATION
A measure of the central tendency of a collection of data. A small
standard deviation means the data do not vary widely. A large
standard deviation means the data vary more widely. Standard
deviation is calculated as the square root of the variance, where
variance is the average of the squared deviations about the mean.
STORAGE INTERVALS
The period of time that data are gathered before being stored to
non-volatile memory. In SymphoniePLUS3 loggers, the storage
interval is always 10 minutes.
SYMPHONIEPLUS3 DATA
RETRIEVER
Software supplied by NRG Systems used to produce versatile tab-
delimited text Data Retriever files from raw data files collected by
the SymphoniePLUS3 logger. Text files can be used with a wide
range of data processing software, including SQL databases,
Microsoft Excel, Microsoft Access, and more. Supports
international numeric formats.
TALLTOWER
NRG Systems TallTowers are the original tilt-up tubular steel
meteorological tower. TallTowers are delivered in complete kits,
assembled on the ground and then tilted up and secured with guy
wires.
TEXT EDITOR
A simple utility program that can be used to view or edit text files.
