Ensure that recalibration is carried out by authorised
persons in accordance with national legal
requirements. The year in which initial calibration was
performed can be found after the CE mark on the
rating plate above the number of the notified body
0109 (Hesse Weights & Measures Office).
Recalibration is required in all cases if one or more
calibration seals have been damaged or the calibration
counter reading does not match the number on the
valid calibration counter sticker.
11.2 Check calibration counter reading
The scales for this measuring station are calibrated.
Calibration may only be performed by authorised
bodies. To ensure this, the scales are equipped with a
calibration counter which registers any change in data
relevant to calibration.
If you wish to check that the scales are properly
calibrated, proceed as follows.
1. Ensure that the device is switched off.
2. Press the Start key of the multifunctional
display.
SECA
appears in the display.
3. Press any key on the multifunctional display while
SECA
is shown in the display.
The symbol appears and the current calibration
counter reading flashes in the display for a few
seconds.
4. Compare the calibration counter reading with the
figure on the calibration counter sticker.
The two figures must match for calibration to be valid. If
the sticker and calibration counter do not match,
recalibration is necessary. Contact your service partner
or the seca customer service department.
Should recalibration be necessary, the recalibration
sticker shown to the left is used to identify the
calibration counter reading instead of the seca
calibration counter sticker shown above. This sticker is
secured with an additional seal by a person authorised
to recalibrate. The recalibration sticker is available from
the seca customer service department under the
number 14-05-01-886.
