25. DIFFERENTIAL WEIGHING
< Differential weighing > is a working mode enabling you to analyse changes of mass of
a single sample or multiple samples.
The process is carried out by determining sample’s initial mass, next the sample is subjected to
different processes, as a result some sample’s ingredients are either separated or added. Finally, the
sample is repeatedly weighed (differential weighing). After the final weighing, the balance determines
the difference between the two mass values (initial and final).
Differential weighing mode enables you to:
•
Determine a series , where each series may contain several samples
•
Assign a name for each series, print or export data on a series to a connected USB flash drive;
•
For each sample: determine tare value, initial mass and carry out up to five measurements for
the final mass.
In order to operate differential weighing mode, first it is necessary to enter weighing series to the
database, define samples in the series, next trigger the series. To create series go to series
database. For more information on how to create series read further down this user manual.
