8. Servicing/recalibration
Have the scales recalibrated by authorised persons in accordance with national legal re-
quirements. The year of initial calibration can be found behind the CE symbol on the rating
plate above the number of the appointed office, 0109 (Hessen Weights & Measures Of-
fice). Recalibration is required in all cases if one or more calibration seals have been dam-
aged or calibration counter contents does not match the number on the valid calibration
counter sticker (c.f. "Checking that the contents of the calibration counter are correct").
We recommend having your scales serviced by your local service agent before having it
recalibrated. Seca Customer Service will be pleased to give you further assistance.
