Preselections for the titration sequence
Type of drift correction (auto, man., OFF)
auto
: drift value at start is valid and deducted.
Value for manual drift correction (0...99.9 ug/min)
Request of identifications after start of titration (id1,
id1&2, all, OFF)
After start, sample identifications can be requested
automatically: only id1, id1 & id2; all three id's or no
inquiries.
Request of sample size after start of titration (value, unit,
all, OFF)
all
: the value and the unit will be requested.
The unit will be overwritten by the method-specific unit,
see below.
If an inquiry is ≠
OFF
:
Titrate during the requests (OFF, ON)
With
on
the titration starts during the requests after 6 s.
The calculation of the result and the output of data only
take place when the inquiries have been exited.
Method-specific unit of sample size (g, mg, ug, ml, ul,
pc, -, 5 ASCII)
At the start of the method the sample size unit is over-
written by the method-specific unit which has been
preset.
Limiting value check for sample size (ON, OFF)
With
on
the error message
sample size out
appears if
the entry is outside the set limits. The limiting values
are shown in the display window.
The absolute value of the limit is checked during sam-
ple size input and during the calculation of the results.
If
on
has been set:
Lower limit for sample size (0.0...999 999)
Upper limit for sample size (0.0...999 999)
Method-specific text for id1 (10 ASCII-characters)
Appears in the display and printout.
The text is without meaning for work with the silo mem-
ory.
(Similar for Id2 and Id3.)
Type of generator electrode (no diaph., diaphragm)
For documentation of the titration conditions.
