►
Press [Mode/Enter] until [tAEP] is displayed�
►
Press [Set] and keep the buton pressed�
►

ASP / AEP can only be taught within defined limits (→ 12.1 setting ranges). If the teaching
process is carried out at an invalid pressure, [UL] or [OL] is displayed� After acknowledge-
ment by [Mode/Enter], [Err] flashes, the ASP value / AEP value is not changed�
As an alternative:
Select [ASP] and set measured value at which 4 mA are output (20 mA
►
at [OU2] = [InEG])�
Select [AEP] and set measured value at which 20 mA are output (4 mA
►
at [OU2] = [InEG])�
Minimum distance between ASP and AEP = 25 % of the final value of the
measuring range (scaling factor 1:4)�
