User input
When the MPI input is activated, the display
is “frozen” and remains “frozen” until the
MPI input is deactivated. Internally the
preset counter continues counting
When the MPI input is activated, the
current count value for the preset that
has just been selected will be adopted
as the new preset value. See also 7.9
When the MPI input is activated, the
preset counter will be set to the value
specified in the parameter SEtPt.
