9.5 Entering the Ab-
solute Pressure
Fig. 15: Default setting „Absolute Pres-
sure“
NOTE!
At high altitudes, the pressure must be taken into
account for an accurate CO
2
measurement.
•
In this case, enter the local absolute pressure
into the measuring device when setting up for
the first time or after a change of the location.
•
To do this, determine the absolute pressure at
the measuring location, e.g. by looking it up on
the Internet.
Default setting: „1013 hPa“ is flashing in the dis-
play.
• P ress the ▲ -key to enter the corect value.
(press shortly: + 1 hPa, press and hold: scroll
values). Scroll range 700 to 1990 hPa.
• Confirm your selection with the ● -key or the
Ξ -key.
• You will then automatically enter the automatic
calibration menu.
