........................
You can produce the record for the weighing results by touching the “Print” key.
The illustration on the left shows an example of a record. Which values are shown on
the record depends on the settings for the weighing record (Section 6.2.8). The
individual items of information on the weighing record have the following meanings:
“Nominal”: Specified target weight
“–Tol”: Specified lower tolerance
“+Tol”: Specified upper tolerance
“1”...“5”: Number and weight of each sample
“n”: Number of samples
“<T–”: Number of samples whose weight is below the lower tolerance limit
“>T+”: Number of samples whose weight is above the upper tolerance limit
“x”: Mean weight of all samples
“s”: Absolute standard deviation
“s.rel”: Relative standard deviation in %
“Min”: Lowest weight measured
“Max”: Highest weight measured
“Diff”: Difference between highest and lowest weight
“Sum”: Sum of all individual weights
6.3.6 Working with identifications
Identifications are descriptive texts of individual weighing procedures which allow unambiguous cross-referencing of weighing
samples to specific jobs or clients. The identifications are also printed on the weighing records, or transmitted to a computer if one
is connected.
For you to be able to work with the identifications, the ID function keys must be activated
(Section 6.2.2).
At the factory, the ID function keys are given the designations “ID1”, “ID2”, and “ID3”.
You can replace these designations by more meaningful titles corresponding to your
application (Section 6.2.10). The chosen designations (e.g. “Client” for ID1, “Job” for
ID2 and “Lot” for ID3) appear below the corresponding ID function key.
When you work with identifications we recommend you to activate the corresponding
information fields (Section 6.2.4). The information fields have the same designations
as the respective ID function keys.
