Example:
A pressure transducer with 0 ... 400 mbar (nominal pressure) is to be programmed.
The liquid's surface (with a density of 1) is 1 m above the diaphragm at the zero point.
The maximum (span end-point) should be 3 m.

This means that the output must be set to 12 mA during programming.

A change in the zero point has no effect on the adjusted span.
However, if the span end-point is higher than the peak value of the
sensor's nominal pressure range, then the span end-point is fixed at
this peak value and the span is reduced accordingly.
A change in the span setting has no effect on the zero point. The zero
point and span end-point must fall within the sensor's nominal pres-
sure range.
A test / correction of the zero point is suggested after adjusting the
span in order to maintain optimum accuracy.
