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.

Displaying time

After the scale has been switched on, time is displayed for about 2 seconds.
If a printer is connected, the time and date of the weighing operation is printed out in ad-
dition to the weight itself.
Depending on the country to which it is supplied, the display can be in either 24-hour
clock format (e.g. 19:45) or in 12-hour format (e.g. P 7:45).
If TIME appears in the display and 3 alarm signals are heard after the scale is switched
on, this means that the scale has been without a power supply for a prolonged period, so
the clock needs to be reset.

Setting the clock

– To reach setting mode, press the
FUNC key for about 2 seconds.
