5.3 Setting Scaling Values
5-13
The decimal point for scaling display values depends on the decimal
point position [dp] setting.
Set constant K [k] when setting the calculation [cal] to K-A[2] or K-
(A+B)[5]
The decimal point will be at the decimal point position.
Scaling is a function that applies sampled input values to a conversion formula that is set beforehand to
convert each input value to a measurement value.
The input value can be converted to Units used by the system.
The scaling conversion formula for voltage/current input is shown below.
Here,
INP1: The input value for measurement value DSP1
DSP1: The measurement value for input value INP1
INP2: The input value for measurement value DSP2
DSP2: The measurement value for input value INP2
inp: Input value for each sampling
dsp: Corresponding measurement value
