Balance test
During balance operation, in order to confirm its efficiency, it is recommended to
check the weighing precision by putting and object of exactly known weight before
and after series of measurements.
For testing of verified balances use weight standard, having valid standardization
certificates. In case of allowable measurement error exceeding contact authorized
service company to perform balance adjustment.

Balance adjustment
Balance adjustment must be performed by authorized service company
only, as it is connected with necessity of seals breaching, required for

Connection with computer, printer or label printer
The scale is equipped with RS232C or
RS485 (optional), which can be used to
connect external devices such as a computer
or a printer. Detailed way of communication
data is defined by one of protocol:
-
LonG
– protocol to printer and computer
-
ELtron
– protocol to label printer
When cooperating with a printer data is send
automatically after result stabilisation, but
next transmission is possible after removing
previously weighted sample.
When protocol
Long
is chosen scale sends
result of weighting under the influence of
initializing signal from computer, or after
pressing a
key.
When automatic transmission mode is
chosen (function
), a printer data is send
automatically after result stabilisation, but
next transmission is possible after removing
previously weighted sample. The scale sends
following information: successive number of
weighing, date and time (if clock module is
installed )and weighing result.
During transmission communicate Print is displayed. It is also possible by scale to
display text message sent from computer confirming received information.
