| special features |
When calculating different sizes, depending on the selected sensor configuration, air pressure, air density, etc. are included. If these values are not available internally from sensors, they can be entered by the Modbus master into the corresponding registers of this measuring device. These values are therefore used for the calculation instead of default values. Further information can be found in the current MODBUS system description. |
