excitation
Nominal voltage required for excitation of a circuit.
GSM cellular
Global System for Mobile telecommunications. GSM is the digital cellular
phone system widely deployed in Europe and elsewhere to replace the
various analog systems that were in use before GSM was adopted.
GPS
Global Positioning System
non-volatile
Computer storage that is not affected by a loss of power. The SymphoniePRO
logger uses non-volatile data storage and therefore does not require a battery
to retain information in its memory.
offset
Also known as intercept. The offset is the measured value for zero output
from a sensor. SymphoniePRO includes an offset field that can be used for
sensors that have non-zero offsets or to correct for wind direction sensors
that are referenced to directions other than true north. The number that you
enter in the offset field is added to the value that is recorded by
SymphoniePRO. For example, the NRG 110S Temperature Sensor outputs 0
volts at -86.39 °C. The offset you would enter for the NRG 110S sensor is –
86.39.
print precision
Print precision is the number of decimal places you specify in scaled data
numbers. For wind assessment studies, specifying two decimal places is
appropriate. For example, print precision of (###.##) yields a number up to
999.99.
PV panel
Photovoltaic panel. A 15 watt PV panel is an available option for the
SymphoniePRO logger. The PV panel attaches to the tower with a mounting
bracket and uses solar energy to charge the iPack’s batteries.
P-SCM
Signal Conditioning Module. An optional plug in module that provides the
electronics to configure the input on channels 20 - 26 on the SymphoniePRO
logger for a particular sensor. The P-SCM tells the logger whether the sensor is
a vane or has a linear signal.
