7.4.9.3 Manual adjustment n+1 (F1.3)
You can use this function to perform a manual adjustment of the on-load tap-
changer starting from the current tap position through to the highest tap posi-

If you perform a manual adjustment with the busbar closed, you must check
that the measured voltage is within the permitted range after the tap change
operations.
To start the manual adjustment n+1 function, proceed as follows:
