Balance checking
It is advised to check scale indication accuracy before and after series of
measurement using any load with known weight.
To check the scale with legal verification use a calibration weight with valid
calibration certificate. In case permissible error is exceeded it is advised to contact
the nearest service to calibrate the scale.

Scale adjustment
To adjust a balance it is necessary to break protective marks, therefore
to calibrate the scale please contact the nearest service.

Connecting 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.
