CALIBRATION WITH SAMPLE WEIGHTS
The calibration method described here must be carried out using sample weights and/or product pre-
weighed on a sample scale.
Always perform zero calibration before proceeding with the full scale calibration.
CAUTION! If the instrument is switched off without leaving the set-up menu, the programmed settings
are not stored.
If, after calibration, the system has linearity errors, it must be checked that the weighed structure
is completely free from mechanical constraints.
OPERATION KEYS
DESCRIPTION
Zero calibration: carry out the operation with the scale unloaded but
complete with the tare weight, with stabilized weight. The displayed
weight must be reset; this operation can be repeated several times.
Calibration with sample weight: before carrying out this operation,
load the sample weight on the scale and wait for it to stabilize. The
display shows the measured value to be calibrated; set the correspon-
ding weight value via touchscreen. If the set value is higher than the
resolution offered by the instrument, the setting is not accepted and
the display shows an error message for a few seconds. This operation
can be repeated several times.
Activate linearization with sample weights. Up to 5 linearization
points on a positive scale can be set. During the linearization phase,
in the weight dial the progressive linearization points are displayed
(eg "LIN 1") alternating with the current weight.
Press the F.S button to set the value of the sample weight loaded on the
scale. To end the procedure, press the LIN button again; it is possible
to set a number of points lower than 5.
Exit button from the calibration function.
