2.4 Intended use
_
_
_
The device measures the absolute pressure in the air.
The ambient pressure is measured directly via the integrated sensor. Pressure equali-
sation between the unit and the environment takes place via a water-impermeable
membrane on the front side.
Applications include:
-Barometric measurements (e.g. weather)
-Elevation determination
The device must only be used under the conditions and for the purposes for which it
was designed.
It must be handled with care and used according to the technical data (do not throw,
strike, etc.). Suitable measures must be used to protect the pressure equalisation
opening and be protected from dirt.
2.5 Qualified personnel
For commissioning, operation and maintenance, the relevant personnel must have
adequate knowledge of the measuring process and the significance of the measure-
ments. The instructions in this document must be understood, observed and followed.
In order to avoid any risks arising from interpretation of the measurements in the
concrete application, the user must have additional expertise. The user is solely liable
for damages/danger resulting from misinterpretation due to inadequate expertise.

4.2 Open the adjustment menu
The sensor adjustment can be adjusted with the zero point correction and the gradient
correction. If an adjustment is made, you change the pre-adjusted factory settings.
This is signalled with the display text PR.OF or PR.SL when switching on.
1. Switch the device off.
2. Hold the down button and press the On/Off button to switch on the device and
open the Adjustment menu.
3. The display shows the first parameter. Release the down button.

5 Measurement Basics
5.1 General information about absolute pressure measurement
_
The device measures absolute pressure. However, this should not be confused with
the "sea level air pressure" indicated by weather stations. The altitude-based air
pressure decrease is calculated for these pressure specifications.
The device is capable of correcting this air pressure altitude correction.
To do this, set the parameter value SEA.L in the Configuration menu to YES and enter
the current altitude above sea level in the parameter value ALT,.
The nautical norm correction must be deactivated for vacuum measurements.
5.2 Altimeter
If metres or feet are selected as the display unit in the Configuration menu, the device
is in altimeter mode.
The unit calculates the current altitude from the current air pressure: At higher alti-
tudes, the air pressure is lower. It is important to note that not only changes in altitude
but also the weather influence the measurement. To correct this weather influence, the
displayed altitude can be corrected via the keys.
Altimeter display: In the Altimeter operating mode, you will be prompted to enter the
current altitude after pressing the Function key for 4 s.
Note: The first time you are prompted after switching on the device, the value is set to
the alti value in the Configuration menu. (default value for starting point)
The current value is retained for all further calls.
Note on min/max display: in the secondary display, the sum of the altitude metres
covered is also shown
for min: dESC - descent, for max: ASC - ascent
5.3 Special functions
_
5.3.1 NVLL Tare function
If a pressure unit is selected as the display unit in the Configuration menu, the device
is in barometer mode.
After it is switched on, the device starts up in standard measuring mode, the special
function “tare” is started by pressing and holding the Function key for 4 s..
Barometer display: The display can be zeroed by pressing the Function key for 4 s.
If the tare function is activated, NVLL blinks in the lower display.
The tare function can be reset by pressing the Function key again
for 4 s.

G 1110 Measurement Basics | 5
B-H88.0.01.DK2-1.2 13 / 20
NOTE
The tare function is independent of the zero point correction accessible via the adjust-
ment menu.
5.4 Use of the trend indicator
NOTE
For the trend display, it is necessary that the device has collected a sufficiently large
number of measured values. This is the case for the time bases 1h and 3h only after
this time has elapsed.
The value is therefore not shown in the display before this time has elapsed..
5.4.1 Meteorology: weather forecasting
Observation of variable weather conditions by assessing the rate of change of air
pressure.
To do this, set the device to:

This results in the following display, for example:

□■■□ stable (trend lower 1 hPa)

14 / 20 B-H88.0.01.DK2-1.2
5.4.2 Hiking, cycling, flying, motor sports: use as a variometer
A variometer or inclinometer indicates the change in altitude per unit of time, i.e. the
rate of ascent or descent. Common units are [ft/min] or [m/s] for flight and motor
sports, or [m/h] for example in hiking/running.
NOTE
The output value of the tendency display in the setting 1_S or 60_S shows the current
value for the tendency based on the measurements of the last 5 seconds, scaled to the
selected setting. In the 60_S setting, the resolution is reduced to 1 m or 5 ft.
To do this, set the device to:
Hiking,
cycling
flying,
motor

6 Operation and maintenance
6.1 Battery
6.1.1 Battery indicator
_
If the empty frame in the battery display blinks, the batteries are depleted and must be
replaced. However, the device will still operate for a certain length of time.
If the BAT display text appears in the main display, the battery voltage is no longer
adequate for operation of the product. The battery is fully depleted.
6.1.2 Changing battery
_
DANGER
Danger of explosion!
Using damaged or unsuitable batteries can generate heat, which can cause the batter-
ies to crack and possibly explode!
–Only use high-quality and suitable alkaline batteries!
CAUTION
Damage!
If the batteries have different charge levels, leaks and thus damage to the device can
occur.
–Only use high-quality and suitable alkaline batteries!
–Do not use different types of batteries!
–Remove depleted batteries immediately and dispose of them at a suitable collec-
tion point.
_
NOTE
Unnecessary unscrewing endangers the protection against moisture and should
therefore be avoided.

7 | Disposal G 1110
16 / 20 B-H88.0.01.DK2-1.2
NOTE
Read the following handling instructions before replacing batteries and follow them
step by step.
If disregarded, the device could be damaged or the protection from moisture could be
diminished.
1. Unscrews the Phillips screws (A)and remove the cover.
2. Carefully replace the two Mignon AA batteries (B). En-
sure that the polarity is correct! It must be possible to in-
sert the batteries in the correct position without using
force.
3. The O-ring (C) must be undamaged, clean and posi-
tioned at the intended depth.
4. Fit the cover (D) on evenly. The O-ring must remain at
the intended depth!
5. Tighten the Phillips screws (A).
7 Disposal
Separation by material and recycling of device components and packaging must take
place at the time of disposal. The valid regional statutory regulations and directives
applicable at the time must be observed.
_
NOTE
The device must not be disposed of with household waste. Return it to us,
freight prepaid. We will then arrange for the proper and environmentally-
friendly disposal.
Private end users in Germany have the possibility of dropping off the device at the
municipal collection centre. Batteries must be removed beforehand!
Please dispose of empty batteries at the collection points intended for this purpose.
