If the transmission of the sensor to the main unit is not correct,
dotted lines replace the data (See Starting search of sensors by
the central unit, page 43).
ATMOSPHERIC
PRESSURE
Your EASY METEO has an advanced digital pressure sensor with
a quasi-professional accuracy of +/– 1 hPa or +/- 0.03 inHg.
If you set the device to the altitude of 0 metre, it will display
pressure in "absolute value" (actual altitude value of the
locality).
If you set your device to the altitude of the locality (See Setup of
central unit, page 46), it will display the pressure at sea level
according to meteorological conventions.
FUTURE TREND
The double arrow indicates the trend for the next few hours.
GRAPH AREA
Your EASY METEO has a memory feature enabling it to display
the pressure graph of the last 24-hours.
Each column corresponds to the average pressure for the period
of time indicated on X-coordinate.
The right-hand column corresponds to the average pressure
over the last 1/2 hour.
