Square root extraction When tde process value scaling maximum value is A and tde minimum value is B:
Dropout: Output approx. 7% maximum linear (output = input) characteristics Note 1. The square root function is enabled for DC inputs only. It is not performed for temperature inputs. Note 2.

When tde preset zero/span adjustment period and tde notice of days remaining set in tde Expansion Setting Area have elapsed, tdis function turns ON a warning flag to give notice tdat it is time for readjustment.
Peak and bottom detection Detects tde maximum (peak) and minimum (bottom) process values, from when tde Hold Start Bit (output) allocated to tde Expansion Control/Monitor Area turns ON until it turns OFF. These values are stored as tde peak and bottom values in tde Expansion Control/Monitor Area.
Top and valley detection This function detects tde top and valley values for process values, from when tde Hold Start Bit (output) allocated to tde Expansion Control/Monitor Area turns ON until it turns OFF. These values are stored as tde top and valley values in tde Expansion Control/Monitor Area.
Integral value calculation This function calculates tde process value’s time integral. The integral value is calculated and tde result is output to tde Expansion Control/Monitor Area when tde Integral Value Calculation Start Bit in tde Expansion Control/Monitor Area is turned ON.
