Process value 1 and Process value 2 ✳
"Signal value 1" (X1), "Signal value 2" (X2), "Process value 1" (Y1) and "Process value 2" (Y2) are used to calculate the linear function (f). The linear function is needed to calculate the present value out of the measured signal value. Unit: Depends on the process value. Range: -1 if the function needed to calculate the present value out of the measured signal value is completely defined by the selected signal type. Example: Ni1000 Any Value ≠-1 if the function needed to calculate the present value out of the measured signal value is not completely defined by the selected signal type.

Process value 1 and Process value 2 ✳

"Signal value 1" (X1), "Signal value 2" (X2), "Process value 1" (Y1) and "Process value 2" (Y2) are used to calculate the linear function (f). The linear function is needed to calculate the present value out of the measured signal value.

Unit: Depends on the process value.

Range:

-1 if the function needed to calculate the present value out of the measured signal value is completely defined by the selected signal type. Example: Ni1000

Any Value ≠-1 if the function needed to calculate the present value out of the measured signal value is not completely defined by the selected signal type.

Pulse integration time ✳
"Pulse integration time" defines the time in seconds to be used to accumulate impulses and to calculate the respective impulse frequency.
