3.15 Storing determination results and silo calculations
756/831 KF Coulometer, Instructions of Use 51
After several samples have been processed, the silo memory report can have the
following appearance (printout with <PRINT><SILO><ENTER>):
The silo lines can be marked as follows (at very left of report):
+ Silo line has been processed. It cannot be edited anymore.
* A silo line not yet processed has been deleted.
- A processed silo line has been deleted and hence removed from the silo
calculations.
/ The last processed silo line. Recalculation will be considered e.g., if the sample data
of this line are changed.
No marking: The silo line is awaiting processing.
For silo lines
≥ 100, the first digit will be overwritten by the marking.
3.15.2 Silo calculations
Mean values and standard deviations of the results available in the silo memory can
subsequently be calculated for the entire series.
The following details can be entered in the method under <DEF>:
>silo calculations
C24=
C25=
match id: OFF
Silo calculations (in expert mode only)
Assignment to C24 (RSX, H2O, CXX)
Calculated results (RSX), endpoint (H2O) and variables
(CXX) can be stored as C24.
Identical for C25.
Which sample identifications must match in order to
combine of the results (id1, id1&2, all, OFF)
OFF
means no matching id's, all samples which have
been processed with the same method are combined,
see examples below.
