5.10.3 Zero point calibration of
analogue output

With this menu item you can adjust the zero point of the analogue output (4mA). The zero point
correction is only possible when the minimum output is 2 V or 4 mA, i.e. not possible when minimum
output is 0 V or 0 mA.
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 analogue output only after
having opened the menu.
Calibration AO 1
Connect ampere meter to the analogue output.
