Comparing Measured Values (Previous Value Comparisons) - Omron L User Manual

Comparing Measured Values (Differentiation
Function)
Use the differentiation function to detect only sudden changes in the measured values that
occur during very short periods of time.
The differentiation function detects changes between the present value and the measured
value that is in effect just before the comparing pitch. The coefficient of this comparing pitch is
defined as the differentiation cycle.
The relationship between the differentiation cycle and comparing pitch can be calculated by
the following equation.
Comparing pitch = Differentiation cycle x 150µs
Example: When differentiation cycle = 10

If you want to detect changes in hold value, use the previous value comparison function.
