Scaling Formulas
The scaling formula for a DTAM display value is:
Displayed Value = m x Register Value + b
Where:
Display Maximum Value Display Minimum Value
Register Maximum Value Register Minimum Value
m =
Display Minimum Value ( m x Register Minimum Value )
b =
The scaling formula for an entered valued is:
Register Value = m x Entered Value + b
Where:
Register Maximum Value Register Minimum Value
m =
Register Minimum Value ( m x Entry Minimum Value )
b =
Entry Maximum Value Entry Minimum Value
Scaling example: Register Range = 0 ! 4,095
Display Range = -100 ! +300
Actual Register Value = 2,047
300 - (-100)
4,095 - 0
m =
-100 - (0.0977 x 0) = -100
b =
= 0.0977
Displayed Value = 0.0977 x 2,047 + (-100)
= 99.9919
= 100
