------
The weight value is unstable or zero setting is not possible. Check the environ-
mental conditions (drafts, vibrations, etc.). If necessary, change the filter set-
tings in the menu (menu block "S4", see Chapter 4). Under certain conditions
there could also be a difference of air pressure between the scale housing and
the surroundings. Unscrew the rear leveling screws until the ventilation openings
under them are free. If water drains out, contact you dealer.

When zero was set there was a weight on the scale. When the load is removed
this error message appears. Ensure that there is no weight on the pan and then
press the a key. If the error message occurs again, the scale must be ad-
justed (calibrated).
Note: If the setting "S11" = "Off" was selected in the menu (Chapter 4.2), when
zero-setting is done with a weight on the balance and the weight is then re-
moved, the negative weight value is displayed instead of this error message.

Cleaning the scale
• Disconnect the scale from the power supply before starting to clean!
• Use a soft cloth (no acids, alkalis, or strong solvents).
• Do not use abrasive cleaning agents: they can scratch the display.
• Do not clean the scale with a high-pressure cleaner.
• If badly soiled, remove the weighing pan and leveling screws, and clean them separately.
• Observe company-internal and industry-specific regulations regarding cleaning intervals and permitted
cleaning agents.
