Calibration Factory calibration certificate (optional: DKD/DAkkS calibration
certificate)
1)
Theroretical starting value; corresponds to the pressure value generated by the piston (by its own weight). To optimise the operating characteristics more weights
should be loaded.
2) The lowest pressure change value that is reached based on the standard weight set. A fine weight set is also available for lower values.
3) The accuracy is in reference to the measurement value, from 10% of the measurement range. A fixed error is considered in the lower area in reference to 10% of
the area.
4) Measurement uncertainty assuming reference conditions (room temperature 20°C, air pressure 1013 mbar, relative humidity 40 %). Corrections may be required for
use without CalibratorUnit.
