Parameters for Analog Output
NOTE: Each of the parameters for output can carry data from either TIE and either path or the
average of the two paths. The TIE and path are selected on the output configuration
screen.
Parameter Name Functional Description
INSTANT VELOCITY
This parameter is the linearized, instantaneous, actual velocity as measured during a
single integration period. It is linearized per the curve developed from site testing
AVE VELOCITY
This parameter is an average of the linearized, instantaneous velocity values from a
number of integration periods. The number of periods is set by the “periods for
averaging” variable. The length of the averaging period will be “seconds of
integration” X “number of periods averaged”.
INSTANT RAW VELOCITY
This parameter is the raw, unlinearized, instantaneous, actual velocity as measured
during a single integration period.
AVE RAW VELOCITY
This parameter is an average of the raw unlinearized instantaneous velocity values
from a number of integration periods. The number of periods is set by the “periods
for averaging” variable. The length of the averaging period will be “seconds of
integration” X “number of periods averaged”.
INSTANT ACT VOLUME
This parameter is the linearized, instantaneous, actual volume as measured during a
single integration period. It is linearized per the curve developed from site testing .
AVE ACT VOLUME
This parameter is an average of the linearized, instantaneous actual volume values
from a number of integration periods. The number of periods is set by the “periods
for averaging” variable. The length of the averaging period will be “seconds of
integration” X “number of periods averaged”.
INSTANT STD VOLUME
This parameter is the linearized, instantaneous, standard volume as measured during a
single integration period. It is linearized per the curve developed from site testing
and corrected to standard temperature and/or pressure conditions.
AVE STD VOLUME
This parameter is an average of the linearized, instantaneous standard volume values
from a number of integration periods. The number of periods is set by the “periods
for averaging” variable. The length of the averaging period will be “seconds of
integration” X “number of periods averaged”.
INST MEDIUM INT TEMP
This parameter is the instantaneous temperature of the medium as measured by the
monitor during a single integration period.
AVE MEDIUM INT TEMP
This parameter is an average of the instantaneous temperature of the medium as
measured by the monitor during a number of integration periods. The number of
periods is set by the “periods for averaging” variable. The length of the averaging
period will be “seconds of integration” X “number of periods averaged”.
INSTANT SOUND SPEED
This parameter is the instantaneous speed of sound through the medium as measured
by the monitor during a single Integration Period.
AVG SOUND SPEED
This parameter is an average of the instantaneous speed of sound values as measured
by the monitor during a number of Integration Periods. The number of periods is set
by the “periods for averaging” variable. The length of the averaging period will be
“seconds of integration” X “number of periods averaged”.
AVG SPAN HIGH
This parameter is an average of the instantaneous span high values as measured by the
monitor during a number of Integration Periods. The number of periods is set by the
“periods for averaging” variable. The length of the averaging period will be “seconds
of integration” X “number of periods averaged”.
AVG SPAN LOW
This parameter is an average of the instantaneous span low values as measured by the
monitor during a number of Integration Periods. The number of periods is set by the
“periods for averaging” variable. The length of the averaging period will be “seconds
of integration” X “number of periods averaged”.
