To Calibrate the Barometric Pressure

2) To be able to read the current barometric

pressure as a pressure referring to sea-level

although at an altitude, calibrate as follows:

Check the current altitude (for example 1000m).

Divide 1000/8 (since 1 hPa/mbar is 8m altitude).

Result 125 hPa/mbar. Set offset to +125hPa/mbar.

The reading will now refer to the pressure at sea-

level.

Following the previous 'Setting the Storm Alarm'

section to select the Calibration Display.

In the Calibration Display, press and hold the

[reset] button for 2 seconds to select the

Calibration Setting Display.

When the 'offset value' digits are flashing, press

the [set] or [reset] button to scroll to select the

target offset value (hold down the button to scroll

the setting at a faster pace).

When the above settings finished, press the

[mode] button once to exit the setting sequence.

1) When the barometric pressure has been

calibrated, the current barometric pressure will

offset by the target offset value.
