The value for the right-hand limit of a plot must not necessarily be the
larger one. By exchanging the limits the plot of the particular quantity
can be mirrored.

req.smpl.size
req.ident.: id1, id1 & id2, OFF
For sample identification you can document each measured value with
two Ids in the report header. These can either be predefined under
CONFIG/Report and included in each report or, depending on the Pre-
selections setting, they can be requested before each measurement.
Please note that sample identifications requested as a preselection be-
fore the measurement will also be stored as an entry under CON-
FIG/Report (see Section 5.1). This means that they are again availa-
ble for the next measurement.
req.smpl.size: value, unit, all, OFF
The parameters smpl.size and smpl.size unit described in the
calculation parameters (see Section 6.5.4) can also be requested for
each measurement. This allows an individual sample data input.
Just as in the request for the sample identifications, the sample size re-
quested here will also be stored under PARAMETER Conc/calcula-
tion parameters and is available for the request before the next
measurement.
