Correction of pressure reading to the sea level
Select menu item Calc P (calculation of pressure) and press
the ENTER key. The actual pressure reading is displayed (LCD
upper line, hPa) and the value of correction constant is displayed on
the LCD lower line (DIF). Use the arrow keys to set the appropriate
value of adding constant. At the same time the actual pressure
reading on the upper line is updated. Actual pressure value above
sea level is possible to gain e.g. from nearest weather station. The
new value of adding constant will be stored after pressing ENTER. This is indicated by YES on
LCD the lower line. It is possible to leave this mode without any change by pressing the MENU
key. The above procedure is necessary to repeat any time after instrument is moved to the
location of different altitude above sea level. If you set the adding constant (DIF) to zero,
instrument will display the absolute pressure again.
Alarm indication and setting
It is possible to set lower and upper limit for each measured
quantity. Breaking of the limit is indicated by blinking of
the appropriate value on the display. If a new alarm was indicated
(i.e. it was not active in the previous measurement), display starts to
display the value out of limits. If at least one alarm is active, audio
indication can be activated, if menu AUDI "On" is selected (see
setting described above). Alarm activation of each value can be
disabled by setting lower alarm limit of the desired value up to its
maximum. This is indicated by OFF reading at the position of
numeric value. Value of upper limit of the same alarm is indifferent.
To set alarms press MENU key, select ALAR from menu items
and confirm by pressing ENTER key.
The following description of alarm setting is a model for alarm
setting of all measured quantities.
Reading ALLO indicates adjusted lower alarm limit (here air
temperature). Set the desired value by means of the arrow keys.
Press and hold the arrow key UP to make value increase fast. Press
and hold the arrow key DOWN to make value decrease fast.
Release the arrow key and press ENTER to confirm new limit.
