9.4.11 Air pressure ( BOD Special operating mode)
Here you can set the air pressure at the measuring location. The setting
range is 500 hPa to 1100 hPa. The default setting is 954 hPa.
The air pressure is directly connected to the height above sea level (the
air pressure influences the equation for the BOD determination). There-
fore, if you change one of these two parameters, the other one is also
changed automatically.
9.4.12 Limit pressure ( Pressure p operating mode)
Select the limit pressure here, i. e. the pressure difference compared to
the starting pressure (negative or positive pressure) at which the control-
ler takes the relevant sample into a list which is automatically displayed
after the data have been called up.
With this function, the course of the test can be monitored.
