Parameter Descriptions
DECIMAL PLACE
Range: See below
Select the position of the decimal point.
Enumerated Value : Position
0 : DEFAULT
1 : X.XXXX
2 : X.XXX
3 : X.XX
4 : X.X
5 : X.
FORMULA
Range: See below
Select a formula where A, B and C are the coefficients listed below, and X is the value to
modify.
Enumerated Value : Formula
0 : A/B * X + C
1 : A/B * (X+C)
2 : A/(B * X) + C
3 : A/(B * (X+C))
COEFFICIENT A
Range: -300.00 to 300.00
Coefficient used as defined by the formula.
COEFFICIENT B
Range: -300.00 to 300.00
Coefficient used as defined by the formula.
COEFFICIENT C
Range: -300.00 to 300.00
Coefficient used as defined by the formula.
HIGH LIMIT
Range: -300.00 to 300.00
Use high limit to set a maximum value for the modified parameter on the keypad. Setting the
HIGH LIMIT lower than or equal to the LOW LIMIT makes the parameter “read-only”.
LOW LIMIT
Range: -300.00 to 300.00
Use low limit to set a minimum value for the modified parameter on the keypad. Setting the
HIGH LIMIT higher than or equal to the HIGH LIMIT makes the parameter “read-only”.
UNITS
Range: max length is 6 chars
A 6 character label that is displayed as the parameter units.
