8.1.3 Non-certifiable scales with strain gauge load cells (standard resolution 2x3000d)
The following data apply to all non-certifiable compact scales with standard strain gauge load cells.

Note on calibration
It is recommended that non-certifiable scales are also calibrated under full load. If required, however, these can also be
calibrated at less than full load (minimum approx. 25% of full load). The calibration tolerance given in the table applies to
calibration under full load. It is reduced in proportion to the calibration weight used.
Note on linearity
The linearity of noncertified scales must be verified at 0%, 50% and 100% of the full load. Tolerances are given in the
calibration diagrams in the preceding subsection.
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.
