Notes to hPa sensitivity setting for weather forecasting:

The hPa (Hekto-Pascal) pressure sensitivity can be set to suit

the user’s requirement for weather forecasting from 2 hPa to 4

hPa (see Basic Programming below). For areas that experi-

ence frequent changes in air pressure (which does not neces-

sarily reflect a change in the weather) requires a higher hPa

setting compared to an area where the air pressure is stag-

nant. For example if 3 hPa is selected, then there must be a

fall or rise in air pressure of at least 3 hPa before the weather

station will register this as a change in weather.

The air pressure reading is displayed here. Press the PRES-

SURE key to toggle between relative and absolute air pres-

sure displays.

Notes to Absolute and Relative Air Pressure:

Absolute air pressure provides the display of the true meas-

ured air pressure of the current time and location. This is not

programmable and the absolute air pressure range of the

weather station is from 300 hPa to 1099 hPa (standard air

pressure at an altitude of 9,100 meters is around 300 hPa).

Relative air pressure is the one value that is calculated back

to sea level from the local absolute air pressure and can thus

be taken as a reference for weather condition and weather

development for the entire country. It can be programmed to

represent your local surroundings. Since the relative air

pressure is also the one value given by various newspapers,

TV and radio broadcasting stations in their daily weather

forecasts for their respective locations, users can set the

relative air pressure of the weather station to this value to

represent readings your their area (see Basic Programming

Modes below).
