8.12.1 Zero Calibration of Analog Output

With this menu item you can correct the zero-point of the analog output (4mA). The zero-point correction is only
possible when the analog output is in active mode.
The error message of the output monitoring is suppressed as long as the menu Calibration AO is open.
Therefore, connect the Ampere Meter (measuring range 20 mA DC) to the analog output only after having
opened the menu.
Calibration AO 1
Connect amperemeter to the analog output.
