9. Servicing/recalibration
Have the scale 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 essential if one or more security marks are damaged or the calibra-
tion counter does not match the number on the applicable calibration counter mark (cf.
page 24).
We recommend having your scale serviced by your local service agent before having it
recalibrated. seca Customer Service will be pleased to give you further assistance.
