Measurement Value Calculation
Fixed Scale
x0.1, x0.01, x0.001
The real value is the value measured by multiplying it by the fixed scale [x0.1, x0.01, x0.001].
Real measured value = Measured value x Fixed scale
Example)
If Frequency register address [40141] = 600, Fixed scale = x0.1,
Real Frequency = 600 x 0.1= 60.0
Variable Scale
VSA[Scale register address]
VSA is Variable Scale Type A. The real value is the value measured by multiplying it by the variable
scale value, and x0.1. Variable scale value indicates one of the values: 1, 10, 100, and 1000.
Real measured value = Measured value x Variable scale value x 0.1

40109 R Voltage scale UINT16
If Scale is VSA[40109],
Voltage A register address [40101] = 222, VSA[40109] = Voltage scale [40109] = 10,
Real Voltage A = 222 x 10 x 0.1= 222.0
