Dead-band function


With the Dead-band function, you can freeze the AI reference for a defined area
(that is, dead-band) or ignore a low AI reference caused by possible
electromagnetic interference issues.
In voltage mode:
AI dead band value = 10V* AI dead band (12.110) * 0.01
In current mode:
AI dead band value = 20mA* AI dead band (12.110) * 0.01
