* with approved scales the overload display may only appear when the load is more then 9d above the maximum load
** for scales with IP65 protection degree (FTB)
Note on linearity
The linearity of certified or certifiable scales must be verified at 0%, 50% and 100% of the full load. Tolerances are given
in the following calibration diagrams.
If there are not enough test weights available to
verify the linearity at 0%, 50% and 100% of the full
load, then the preset values can be changed.

Note on calibration
Certified/certifiable scales should be calibrated under
full load. For the limits of permissible calibration
errors for each weighing range, refer to the diagrams
on the next page and the example below:
Example: Maximum permissible errors for 15 kg
(Weighing range 1: 6 kg /2 g)
