The above function codes are generally used to correct the zero drift of analog output and the deviation of
output amplitude. It can also be used to customize the required AO output curve.
If the bias is represented by b, the gain is represented by k, the actual output is represented by Y, and the
standard output is represented by X, then the actual output is:
Y = kX + b
Among them, 100% of the bias coefficient of AO1 corresponds to 10V (or 20mA), and the standard output
refers to the amount of 0V ~ 10V (or 0mA ~ 20mA) corresponding to the analog output without bias and gain
correction.
For example, if the analog output content is the operating frequency, and you want the actual output to be 8V
(or 16mA) when the frequency is 0, as shown in the figure below, you need to set the zero offset to "80%"; If
you want to output 3V (or 6mA) at the maximum frequency, as shown in the figure below, you need to set the
gain to "- 0.50".
