ANALOG GLOBAL - INTEGRAL
AVERAGE MODE
The integral mode can be used to obtain
an average value for a measured variable
over a given time period. For example, this
can be used to obtain the average outside
air temperature for a month. The ECC/
WCC II system will take an outdoor air
temperature reading at programmed time
intervals, for example, 1 reading every
minute. The value of the analog global
will be the average temperature for all of
the readings taken since this mode was
started. To understand this mode better,
think of the data as being in a “window”
which moves along the time axis and has
all of the outside air temperature readings
in it since the beginning of the month. The value of the analog
global is the average of all the temperature readings that are in the
window. As the next temperature reading becomes available, the
window increases in size until the value of the analog global is
automatically cleared or erased at the of the month.
