8.1.2 Certifiable and certified compact scales with strain gauge load cells (premium)
The following data apply to all certifiable or certified compact scales with premium strain gauge load cells.
Scale capacity
Weighing range
Resolution
Certification class
Readability
Linearity
Repeatability s
Calibration weight full load 1)
Calibration weight minimum 1)
Weight class
Corner load test weight
Corner load tolerance
Overload stop
Corner load stop
* with approved scales the overload display may only appear when the load is more then 9d above the maximum load
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.
1) 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.
