Watlow F4T • 182 • Chapter 5 Function Reference
Offset
Adjustment added to the result of the calculation.
Range: -99,999.000 to 99,999.000
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
Absolute Difference
This function calculates the absolute value of input X minus input Y. A filter and offset may be
applied to the calculated value. The output has the units of input x.

The filtered result of the absolute value of (X – Y) plus the
offset
Function
To calculate the absolute value of one input subtracted from another, set Function to Absolute
Difference.

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
Minimum
This function selects the minimum of up to four inputs. Only inputs connected to a source are
considered. A filter and offset may be applied to the output. The output has the units of the
signal with the minimum value.
