11.2.3 Applications subject to weights and measures legislation
The maximum resolution (maximum load / interval) of scales subject to weights
and measures legislation is 10.00 increments. Additionally, the following set­
tings must be made for the parameters in the
Adaptation group:

Subject to certain preconditions, the OFF setting is also allowable here, such as for tank weighers.
After calibrating the scale, the approval parameters can be saved to the EEP­
ROM of the A/D converter, where they are retained even in the event of a
power outage. For applications subject to weights and measures legislation,
the covering and lid must be sealed by adhesive labels so that the position of
the calibration switch can no longer be changed.
►
Unscrew the covering of the calibration switch on the front of the housing.
You can use the now visible small calibration switch S1 to save the calibra­
tion data to the EEPROM locked safe against power outage:
