Ø Theoretical starting value; corresponds to the pressure value generated by the piston (by its own weight). To optimize the operating characteristics, more weights should be loaded.
Ø The smallest pressure change value that can be achieved based on the standard weight set. To reduce this, a set of trim-masses is available (see accessories).
Ø The accuracy from 10% of the measuring range is based on the measured value. In the lower range, a fixed error based on 10% of the range applies.
Ø Measurement uncertainty assuming reference conditions (ambient temperature 20°C, air pressure 1,013 mbar, relative humidity 40%). For operation without an Intelligent Calibration Modulel LR-Cal IKM corrections must be made if required.

The weights included in the standard mass set are ideally suited for everyday use. If smaller intermediate values need to be generated, we recommend using a set of trim-masses.
