    X2 Parameter Scaling

    The X2 allows for simple parameter value scaling to be applied internally in the logger. The allowed scaling is done using a second-degree polynomial equation in the form of Ax2+Bx+C. Below are the coefficients as well as their default values. Ax2+Bx+C x: The original parameter value read from the sensor A: Default = 0 B: Default […]
