Scaling

Scaling is available in the Task configuration page for most DAQ channels and can be used to scale the electrical values returned from a DAQ device into real-world, physical units of a sensor.  EveryMeasure supports several types of scaling including:

None

Unscaled values are sent to EveryMeasure.

Linear

Scale the electrical values (x) to the physical values (y) linearly using the equation below, where m is the Slope and b is the Offset.

Sensitivity

Scale the electrical values (x) to the physical values (y) linearly using the equation below, where m is the Sensitivity and b is the Offset.

Dynamic

Scale the electrical values (x) to the physical values (y) linearly using the equation below, where m is the Sensitivity

Table

Scale the electrical values to the physical values using multiple electrical values and their corresponding physical values. Table scaling uses the formula below to calculate the slope (gain) and the intercept to calculate the offset for each consecutive set of values.

Two point

Scale the electrical values to the physical values using the minimum and maximum expected electrical values and their corresponding physical values. Two-point scaling uses the formula below to calculate the slope (gain), and uses the intercept to calculate the offset.

Negate

Scale the electrical values by multiplying by -1
