Linearisation Table
The Linearisation Table provides conversion of the UI physical signal in to an engineering value for
display and control in other areas of an application. Sensor Types 0…5 may be customised to suit
different scaling for a specific active sensor type or to suit a passive sensor element that is not already
pre-programmed as a factory default.

Active Sensor Scalings
Column 1 is the fixed reference to which all display results are based. The range of the reference
column 1 is effectively 0…1000. It is important to interpret the reference values in combination with the
intercept and scaling data at rows 12…14. Taking Sensor Type 2, 0-10Vdc, as an example:
The microprocessor raw count range of 0…1000 relating to 0-10Vdc results in 0…100% display
because the reference column values are being decimal shifted one place to the left (row 13
column 4 = -1
If 0-10Vdc is to be displayed directly as 0-10Vdc then we need to decimal shift -2 at row 13
column 4 and change Units display characters
