Otherwise, the last reported measurement value is continued to be made available for
the application.
Deadband formula:
[ABS (new value – last reported value) > (% of Deadband value × Measured range)]
The measured range is the difference between the parameters Input Max value and
Input Min value .
Measured range = ABS (Input Max – Input Min)
For example, if Input Min = 0, Input Max = 20, Deadband value = 1% and Last
reported value = 10 and if the new measured value is less than 9.8 or greater than 10.2,
the measured value should be reported.
If the value remains unchanged, it is reported after every 30 seconds.
Since the functionality can be utilized in various measurement modes,
the default values are set to minimum. Thus, it is very important to set
correct limit values to suit the application before the deadband
supervision works properly.
