DAQmx Scale Properties

Use the DAQmx Scale properties to configure custom scales.

PropertyDescription
Active Scale Specifies the name of the custom scale to modify. Details
Description Specifies a description for the scale. Details
Scaled Units Specifies the units to use for scaled values. You can use an arbitrary string. Details
Pre-Scaled Units Specifies the units of the values that you want to scale. Details
Scale Type Indicates the method or equation form that the custom scale uses. Details
Linear:Slope Specifies the slope, m, in the equation y=mx+b. Details
Linear:Y-Intercept Specifies the y-intercept, b, in the equation y=mx+b. Details
Map:Scaled Maximum Value Specifies the largest value in the range of scaled values. NI-DAQmx maps this value to Map.PreScaledMax. Reads coerce samples that are larger than this value to match this value. Writes generate errors for samples that are larger than this value. Details
Map:Pre-Scaled Maximum Value Specifies the largest value in the range of pre-scaled values. NI-DAQmx maps this value to Map.ScaledMaxDetails
Map:Scaled Minimum Value Specifies the smallest value in the range of scaled values. NI-DAQmx maps this value to Map.PreScaledMin. Reads coerce samples that are smaller than this value to match this value. Writes generate errors for samples that are smaller than this value. Details
Map:Pre-Scaled Minimum Value Specifies the smallest value in the range of pre-scaled values. NI-DAQmx maps this value to Map.ScaledMinDetails
Polynomial:Forward Coefficients Specifies an array of coefficients for the polynomial that converts pre-scaled values to scaled values. Each element of the array corresponds to a term of the equation. For example, if index three of the array is 9, the fourth term of the equation is 9x^3. Details
Polynomial:Reverse Coefficients Specifies an array of coefficients for the polynomial that converts scaled values to pre-scaled values. Each element of the array corresponds to a term of the equation. For example, if index three of the array is 9, the fourth term of the equation is 9y^3. Details
Table:Scaled Values Specifies an array of scaled values. These values map directly to the values in Table.PreScaledValsDetails
Table:Pre-Scaled Values Specifies an array of pre-scaled values. These values map directly to the values in Table.ScaledValsDetails
