Chapter 5 Function Reference
Average
This function calculates the mean average of up to four inputs. Only inputs connected to a
source are used in the calculation. A filter and offset may be applied to the calculated value.
The output has the units of the signal connected to the top input link.

.
Offset
Adjustment added to the result of the calculation.
Range: -99,999.000 to 99,999
Filter
Set the amount of filtering to apply. Filtering smooths signal fluctuations. Increase the time to
increase filtering. Excessive filtering slows the function’s response.
Range: 0.0 to 60.0 seconds
Switch Over
When SW is off, the output equals input 1. When SW is on, the output equals input 2. A filter
and offset may be applied to the output. The output has the same units as the selected in-
put.
