* Span and Offset allows for the full range of the transducer to be used by the Mercury Switch.
Span is the full range of the transducer
Offset is the value below zero.
An example Transducer setup is: -
Danfoss AKS 33 with range: -1 Bar to 12 Bar
Span would be 190 (13 Bar)
Offset would be -15 (-1 Bar)
