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
calibration counter with the number
shown on the calibration counter stick-
er.
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.
