BAROGRAPH SETTINGS
in the main menu.
You can adjust here the barograph power reserve, the
barometer altitude and the calibration of the pressure
sensor.
Barograph Power Reserve
By selecting the menu entry
BAROGRAPH POWER RESERVE
the adjustment of the
barograph power reserve or switch it off is possible with
the buttons ▲ and ▼.
With active power reserve the device is not completely switched off by the power button.
The Barograph measures with decreased current consumption while the reception part of
the WIB2D is switched off.
If the power reserve is enabled and the battery is weak, the WIB2D does not switch off
completely. The device keeps on recording the air pressure, until the battery is completely
discharged.
With deactivated barograph power reserve or with completely discharged batteries the
Barograph curve gets lost.
Barometer Altitude
By selecting the menu entry
BAROMETER ALTITUDE
the adjustment of the baromter altitude (height of the
device above sea level) in 5 meter steps is possible with
the buttons ▲ and ▼.
With correctly justified barometer height the WIB2D
displays the air pressure referred to sea level.
The adjustment range of the barometer altitude is between 0 and 1000 meter.
Calibration
The typical long term stability of the air pressure sensor of the WIB2D is -1 hPa/year.
Every year the displayed air pressure sinks by approx. 1 hPa. You can correct this by
calibrating the device. You need a reference air pressure referred on sea level. The
baromter altitude must be adjusted correctly before calibration.
In order to calibrate the air pressure sensor please select
the menu entry
CALIBRATION
.
Now adjust the air pressure display (on top of the left)
with the buttons ▲ and ▼ until it is conform to the
reference air pressure.
