7 - Analog Averaging
Allows the user to change the averaging method for
analog inputs. Normally, the system samples analog
points once a second while keeping track of high
and low values for each analog point. After sixty
seconds, the average of these readings and the high
and low values for these points are recorded in the
minute log. To alter this method of averaging,
change the value to one of the values listed in the
parentheses. Zero or one maintains the method
described above; a higher value changes the method
of averaging and the manner by which high and low
values are recorded.
An example of how averaging is altered and how it
impacts high and low recordings is shown here.
• Analog averaging value is set to 5.
• The analog point is a temperature sensor.
• Temperature readings are displayed for an
eleven second period:

Average = 73, High Value = 73, Low Value = 70
Under normal conditions, the average reading would
equal 71, the high value would equal 74, and the low
value would equal 70. By changing the averaging
method, the average reading ends up at 73, the high
value at 73, and the low value for this example
remains the same. In a sense, averaging slows down
the sensor response and the rate of change. This
parameter impacts all analog points.
