6.14. Air pressure measurement
If necessary, activate the air pressure malfunction object. Specify whether the meas-
ured value is, in addition, to be outputted as barometric pressure (see below
Informa-
tion on air pressure
).
Define the send pattern and, if necessary, activate the minimum and maximum value
(these values are not retained after a reset).
Information on air pressure
The unit for air pressure is Pascal (Pa).
1 Pa = 0,01 hPa = 0,01 mbar
The air pressure is specified as "normal air pressure" or as "barometric pressure". The
normal air pressure is the pressure compensated for height and temperature. The bar-
ometric air pressure is the pressure measured directly by the sensor (without compen-
sation).
Switching output sends on change to 1 and
periodically
If switching output = 1
send 1
Switching output sends on change to 0 and
periodically
If switching output = 0
send 0
