This property enables or disables a scale of values for the value sent to or received from a device. If this property is set to True, any value coming from a device suffers a scale adjustment according to DeviceHigh, DeviceLow, EUHigh, and EULow properties before setting it to the Value property. The same behavior occurs when a writing is needed, when the value available in Value suffers a scale adjustment, without changing the Value property, and then sent to a device. If this property is set to False, no scale adjustment is performed in both directions, reading and writing. Default value of this property is False.
