The decimalpoint position is set at the next parameter.Decimal Point PositionSet the required number of decimal places for both thedisplay full scale and display zero values. In the exampleshown above, set the decimal point position to showincrements of 0.1 bar, i.e. 250.0.Display ZeroSet the display value which represents the minimumprocess variable input signal, between –9999 and +9999.In the example shown above, set 50.0. The decimal pointposition is set automatically.Percentage Increment Per Bar (Bargraph)This frame sets the percentage deviation from set pointthat each bar of the Deviation Bargraph represents – seeFig. 4.1 in the Operating Guide.Set the value required, between 1 and 10% of displayspan.Display UnitsSelect the required display units, dEG C, dEG F, or NONEto represent the process variable.Brightness AdjustmentSelect the required display brightness between 4 and 10.Return to top of Display Page or advance to the nextprogramming page.
