11.4. Zeroing
In order to zero mass indication press key.
The mass indication on the display should equal zero, and precise zero and
stability markers should appear.
Zeroing process is tantamount to determining new zero point recognized by
the moisture analyzer as precise zero. Zeroing is possible only in stable status
of display indication.
Caution:
Zeroing the display indication is possible only within the ±2% range of
instrument’s maximal capacity. If zeroed value is above the ±2% of the
maximum capacity, then the software indicates an error message Err2 .
11.5. Tarring
In order to determine net weight of a weighed object, place object’s container
(packaging) on moisture analyzer’s weighing pan, and on stabilization of
measurement result press
key. The display should indicate mass equal
to zero and symbols: Net and . On taking off the weighed load and its
packaging from instrument’s weighing pan, the display indicates sum of total
tarred mass with minus sign.
The software also enables assigning tare value to a product from a database.
Then, on product selection from a database, the software automatically
uploads data on tare value for the specific product.
Caution:
Tarring negative values is impossible. On tarring negative values the moisture
analyzer responds with an error message. In such case zero the indication and
repeat tarring procedure.
