2.7.4.1 Drag pointer
The absolute minimum and maximum values for the measurements since the last
restart or since the last resetting of the drag pointer are shown here. The function
can be used for different measurement variables and is specified, for example,
with the
BC Absolute pressure in the coordinates BC31 Min. drag pointer. and
BC32 Max. drag pointer. With other measurement variables, where this function
can also be used, the settings are also in lines 31 and 32. These values specified
for the "
