EXAMPLE:

‘ Channel 2 is connected to a linear slide potentiometer. It is

‘ necessary to measure the potentiometer’s position as a function

‘ of resistance. A good approximation to the potentiometer’s

‘ transfer function is determined to be:

‘

‘ f(R) = 0 * (R ^ 2) + 0.01 * (R) + 0. |

‘

‘ The following code segment will set up channel 2 (assumed to have

‘ previously been declared as a “User-defined Resistive Sensor”) for

‘ linearizing the potentiometer’s measured resistance value:

CALL Send518Byte (192 + 2) ‘ send command & opcode to 518

CALL Send518Real (0) ‘ send A coefficient to 518

CALL Send518Real (.01) ‘ send B coefficient to 518

CALL Send518Real (.1) ‘ send C coefficient to 518
