18.1. Comparison of sample and (reference) mass standard
Comparison of samples with a mass standard can be carried out through:
− Giving mass of a standard, using < Give reference mass> soft key;
− Accepting current mass loaded on the weighing pan as a reference
mass, using < Set as 100%> soft key;
− Selecting a product from database of products, where parameter mass
of a product entry is defined, using < Database of Products> soft
key.
PROCEDURE 1 – manual declaration of reference mass
•

•
All samples weighed afterwards are compared with the reference mass,
and the display indicates the difference, expressed in [%], for each
weighed sample in relation to the reference mass.
PROCEDURE 3 – selecting a product from Database of Products
•
Press < Database of Products> soft key, select a product entry to be
weighed from a list of displayed products
•
On selecting, the grey coloured workspace automatically updates its
content with data on Reference Mass

Mass of the weighed product is automatically inserted in field: reference
mass, which is activated by pressing < > soft key
•
The display indicates 0.00 % (if the weighing pan is unloaded)
•
All samples weighed afterwards are compared with the reference mass,
and the display indicates the difference, expressed in [%], for each
