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 those two mass values (initial and final).
Differential weighing mode allows you to:
•
Determine a series, 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 detailed procedure informing you how to create series, read later sections of this user
manual.

25.1. Mode Related Settings
The supplementary settings enable you to adjust the working mode to your needs and requirements.
To access the settings follow the below procedure.
Procedure:
1. Press grey workspace area.
2. The following submenus are displayed: Settings, Buttons, Information, Printouts, Series, Profile.
3. Select <Settings> menu.
4. Functions related to differential weighing are displayed.
Differential Weighing mode settings:
•
Threshold: mass value (maximum mass of a sample, e.g. filter)
•
Ambient conditions: use this function to force operator to enter temperature and humidity
prior to weighing operation: <Weighing A, Weighing T+A, Taring T>
•
NO - value not required
•
ONLINE – values taken form ambient conditions module cooperating with the balance.
•
VALUE – values taken from device other than ambient conditions module, must be
entered manually.
•
Maximum quantity of weighings: use this function to declare how many times final weighing
<B> is to be repeated – 5 times maximum, the parameter setting is valid for all measuring
series.
