auto dos
increment 1...n 1.0E-30...0.1...999.9 mL
The particular volume increment must be entered for each addi-
tion of the standard or sample solution.
auto
delta U 1...10...999 mV
Under
auto the required potential difference must be entered.
Please note that the Dosimat Plus must be properly prepared be-
fore the start of an addition run (cylinder freshly filled, air bubbles
removed, etc.).
During an addition you can terminate the run prematurely with it
<MODE>
; only the additions which have already been measured will
be used for the calculation of the result. This manual termination will be
marked in the report.
6.6.2 Preselections
PARAMETER Conc
:
└ preselections
├ req.ident
├ req.smpl.size
└ activate pulse
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.
req.smpl.size : value, unit, all, OFF
The sample size and sample size unit parameters described under the
calculation parameters (see Section 6.5.4) can also be requested be-
fore each measurement. This allows a more individual input of the
sample data.
