7. What do I do if…
… no weight display comes on?
– Is the scale switched on?
– Is the plug contact of the mains unit properly connected to the scale?
– Is the plug contact for connecting the display to the scale correctly connected?
… 0.0 does not appear before weighing?
– Press the Start key again – there must not be any load on the scale – and only its feet
should be in contact with the floor.
… one segment is illuminated constantly or not at all?
– The relevant segment has a fault. Inform Servicing.
… St0p appears in the display?
– Maximum load has been exceeded.
… the display flashes?
– If you have just activated the Hold or Tare function, please wait until the scale has de-
tected a steady weight value. The display will then stop flashing.
– If there has been no activation of a function beforehand, remove the load from the scale
and wait until 0.0 is displayed, then weigh again.
… the display appears?
– The ambient temperature of the scale is too high or too low. Place the scale in an
ambient temperature between +10 °C and +40 °C. Wait about 15 minutes for the
scale to adapt to the ambient temperature and then weigh again.
… the display E and a number appear?
– Switch off the scale with the Start key and start the scale again. The scale will then
work normally again.
If this is not the case, disconnect the power supply by briefly removing the batteries. If
this measure is equally unsuccessful, inform the Service department.
… the weighing range won’t switch?
– Take the load off the scale if necessary.
– Ensure that no special function is active.
8. 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 22).
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.
