Checking that the contents of the calibration counter are correct
This seca scale is calibrated. Calibration may be performed only by authorised centres.
To ensure this, the scale is fitted with a calibration counter which records any change to
data relevant to calibration. If you want to check whether the scale is properly calibrated,
proceed as follows:
– If necessary, switch off the scale.
– Keep any key depressed and start the
scale.
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-calibration is re-
quired. Contact your service agent or
seca Customer Service.
If a supplementary calibration is necessary,
then the supplementary calibration mark il-
lustrated opposite is used to record the cal-
ibration counter position instead of the seca
calibration mark shown above. This mark is
secured with an additional seal by the per-
son authorised to perform the supplementa-
ry calibration. The supplementary calibration
mark is available from seca Customer Serv-
ice under the number 14-05-01-886.

page 23).

corner of the weighing platform is

display.
Both numbers must match.
