Property of DAQmx Channel

Specifies the scaling type to use when scaling electrical values from the sensor to physical units.

None (10230) Do not scale electrical values to physical units.
Polynomial (10449) Scale values by using an Nth order polynomial equation.
Table (10450) Map an array of electrical values to an array of corresponding physical values, with all other values scaled proportionally. If you specify this scaling type, AI.Max and AI.Min must be within the smallest and largest physical values. For any data outside those endpoints, NI-DAQmx coerces that data to the endpoints.
Two-Point Linear (15898) You provide two pairs of electrical values and their corresponding physical values. NI-DAQmx uses those values to calculate the slope and y-intercept of a linear equation and uses that equation to scale electrical values to physical values.
