Checking that the contents of the calibration counter are correct
These seca scales are calibrated. Calibration may be performed only by authorised cen-
tres. To ensure this, the scales are fitted with a calibration counter which records any
change to data relevant to calibration. If you want to check whether the scales are prop-
erly calibrated, proceed as follows:
– If necessary, switch off the scales.
– Keep the FUNC/SET key depressed
and start the scales.
The current contents of the calibration
counter are shown on the display for a
few seconds.
– Compare the output contents of the cal-
ibration counter with the number shown
on the calibration counter sticker.
For valid calibration, both numbers
must match. If sticker and calibration
counter do not match, then re-calibra-
tion is required. Contact your service
agent or seca Customer Service.
If a supplementary calibration is neces-
sary, then the supplementary calibration
counter sticker illustrated opposite is used
to record the calibration counter position
instead of the seca calibration sticker
shown above. This sticker is secured with
an additional seal by the person author-
ised to perform the supplementary calibra-
tion. The supplementary calibration mark
is available from seca Customer Service
under the number 14-05-01-886.
