6.2.5 Plot parameters
PARAMETER pH
:
├ plot parameters
: ├ left mar. pH
├ right mar. pH
├ left marg.T
The two directly recorded measuring quantities pH and temperature
can be printed out as a function of time in a plot. Under
CONFIG/print
meas. value
the print criterion 'plot' must be selected (see Sec-
tion 5.2). The scales of the measured values axes are determined by
the following limits.
left mar. pH -19.9...0.0...19.9
right mar. pH -19.9...14.0...19.9
left marg.T -999...20...999 °C
right marg.T -999...30...999 °C
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.
6.2.6 Preselections
PARAMETER pH
:
├ preselections
req.ident
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
. This means that they are again available for the next
measurement.
