"Unit group" and "Unit selection"
For parameters where the unit can be switched, the specifications for "Unit group"
and "Unit selection" determine the group to which this parameter belongs and with
which parameter the unit can be switched over.
The standard unit of a parameter is specified in square parentheses after the val-
ues for "Min", "Max", and "Factory setting".
Min
Indicates the minimum value to which the parameter can be set.
Max
Indicates the maximum value to which the parameter can be set.
Factory setting
Indicates the default value, i.e. the value which applies if the user does not specify
a particular value for the parameter (see also "Calculated“).
Example:
Unit group: 7_1, unit selection: p0505
The parameter belongs to unit group 7_1 and the unit can be switched over using
p0505.
All the potential unit groups and possible unit selections are listed below.
