12 Troubleshooting
The scale should be switched off for a short time following an interruption in the pro-
gram sequence and disconnected from mains supply. It is then necessary to repeat
the weighing process from the beginning.
Interruption Possible cause
Weight display is not illumi-
nated.
• The scale is not switched on.
• The mains supply connection has been interrupted
(mains cable not plugged in/faulty).
• Check the fuse of the mains adapter / green LED
is illuminated next to the fuse.
• Mains failure.
• Batteries are incorrectly inserted or discharged.
• No batteries.
Weight display changes
continuously
• Draught/air movement
• Table/floor vibrations
• The weighing plate is in contact with foreign
matters or is installed incorrectly.
• Electromagnetic fields/static charging (choose a
different location for the scale, switch off an inter-
fering device if possible).
The weighing result is
obviously incorrect
• The scale display is not set to zero
• Incorrect adjustment.
• Great fluctuations in temperature.
• Warm-up time was ignored.
• Electromagnetic fields/static charging (choose a
different location for the scale, switch off an inter-
fering device if possible).
Should other error messages occur, switch the scale off and then on again. If the
error message remains, inform the manufacturer.
