Watlow F4T • 163 • Chapter 5 Function Reference
Function
To sum up to four inputs, set Function to Add.
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
Multiply
This function multiplies 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. If any input is an ab-
solute temperature, the output is also an absolute temperature; otherwise the output’s units
are those of the signal connected to the top input.

Function
To compute the product of up to four inputs, set Function to Multiply.

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.
