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.

Both numbers must match.
