Setting the sea level pressure.
• Absolute pressure or local pressure is the actual atmospheric pressure measured by the
main unit.
• Relative pressure is referred as sea level’s pressure and has to be adjusted first to your
local altitude.
• You can set the relative atmospheric pressure directly or via the local altitude. For the
most exact adjustment we recommend to set the relative atmospheric pressure directly.
SETTING OF RELATIVE ATMOSPHERIC PRESSURE (RECOMMENDED)
• Ask for the present atmospheric pressure of your home area (local weather service, www,
optician, calibrated instruments in public buildings, airport).
