The pressure in the still is calculated from the alcohol strength and the boiling or vapor temperature. The computer then compares this with the local atmospheric pressure entered and can thus calculate whether and how much overpressure or underpressure there is in the still without having to measure the pressure. It can do this with the alcohol strength and temperature in the boiler as well as in the vapor or distillate, respectively.
However, such a calculation can of course only make sense if a high accuracy of the measurements is ensured.
Since almost no one has an absolutely accurate thermometer, an additional "thermometer error" can be specified. This can be determined with the help of the calculator Thermometer Error. Temperatures entered here are then those displayed on this thermometer, not the real ones.
