2.1 Explanation of safety symbols
DANGER
This symbol warns of imminent danger, which can result in death, severe bodily injury,
or severe property damage in case of non-observance.
CAUTION
This symbol warns of potential dangers or harmful situations, which can cause dam-
age to the device or to the environment in case of non-observance.
NOTE
This symbol indicates processes, which can have a direct influence on operation or
can trigger an unforeseen reaction in case of non-observance.
2.2 Safety instructions
NOTE

2.3 Foreseeable misuse
The fault-free function and operational safety of the product can only be guaranteed if
applicable safety precautions and the device-specific safety instructions for this docu-
ment are observed.
If these notices are disregarded, personal injury or death, as well as property damage
can occur.
DANGER
Incorrect area of application!
In order to prevent erratic behaviour of the product, personal injury and property dam-
age, the product must be used exclusively as described in the chapter Description
[8] in the operating manual.
–The product is not suitable for use in explosion-prone areas!

2.4 Intended use
The G 1110 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. Relative measurements can also be conducted with the
integrated special function NVLL.
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.
NOTE
Complete evacuation see Vacuum measurements [17].
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. This document makes a valuable contribution to this. 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 con-
crete application, the user must have additional expertise. The user is solely liable for
damages/danger resulting from misinterpretation due to inadequate expertise.

6 Measurement Basics
6.1 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 pres-
sure decrease is calculated for these pressure specifications. The device is capable of
correcting this air pressure altitude correction.
–In the Configuration menu, the parameter value SEA.Lmust be set to YES.
–In the Configuration menu, the actual altitude above nautical norm must be en-
tered in the parameter value ALT.
The nautical norm correction must be deactivated for vacuum measurements.
6.2 Special functions
With the special functions that can be selected via the Configuration menu, the device
can be optimised for special measuring tasks. After it is switched on, the device starts
up in standard measuring mode, the relevant special function is started by pressing
and holding the Function key for 4 s.
6.2.1 NVLL Tare function / Altimeter altitude adjustment
The special function FVNC NVLL has been selected in the configuration menu.
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.
Altimeter display: In the altimeter operating mode, after calling up the tare function,
the user is prompted to enter the current altitude.
NOTE
The tare function is independent of the zero point correction accessible via the set-
tings menu.
6.2.2 AVR0:02 / AVR0:05 / AVR0: 10
Fast measurement with mean value over 2 s / 5 s / 10 s
Mean value mode for measurement of heavily fluctuating pressures.
In the Configuration mode, a special function AVR0:02, AVR0:05 or AVR0: 10 has been
selected.
By pressing and holding the Function key for 4 s. the measurement with mean value
can be activated.
The different mean value times of 2, 5 or 10 seconds can be selected depending on
the requirement.
The first parameter is shown in the auxiliary display.
If the Tare function is activated when called up, this special function AVRcan be reset
by pressing and holding the Function key for 4 s. In order to reactivate the Tare, the
special function must be switched in the configuration menu.

6.3.1 Meteorology: weather forecasting
Observation of variable weather conditions by assessing the rate of change of air
pressure.
To do this, set the device to:
UN,T HPa (international standard)
FVNC NVLL (no signification)
RATE SLO (power saving during continuous operation)
SEA.L YES
ALT, altitude of the location above sea level
TEND 1_H or 3_H: 1 hour (1 hPa / bar level) or 3 hour (3 hPa / bar level)
LCD.2 °(.TE
POFF OFF: continuous operation
This results in the fol-
lowing display, for ex-
ample:
6.3.2 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 t.
To do this, set the device to:
UN,T FT or m (altimeter)
FVNC NVLL for convenient correction of the current altitude
RATE SLO (power saving during continuous operation)
SEA.L NO
TEND 1_S or 60_S (time base 1 second for m/s or 60 seconds for ft/min)
LCD.2 TEND or for more information: °(.P.T or °F.P.T
POFF OFF: continuous operation
This results in the following
display, for example:

trend: + 0,4 hPa per hour
□■■□ stable (trend lower 1 hPa)
display unit m or m/s
current altitude above sea level
trend: - 2,8 m per s
□■□□ slightly falling

6.4 Protection of sensors with use of filter
membranes
The product and the sensor are effectively protected by a filter membrane. This pre-
vents the product from being destroyed by water, for example.
The membrane is located under the pressure equalisation openings:
Front view with
pressure equalisation openings
NOTE
The membrane provides good protection against water penetration.
If the membrane is wetted by water, the pressure balance between the environment
and the device can be impaired, which can lead to sluggish response and falsified
measurement results.
The membrane can be freed from a large part of the water by shaking it downwards
and blowing it out carefully. To ensure proper functioning, the membrane must be
completely dry..
NOTE
Do not attempt to remove dust or other foreign objects from the pressure equalisation
openings with a wire or other pointed object. This may damage the membrane, com-
promising protection against dust and water ingress.
Shaking downwards and blowing out carefully can remove most of the foreign matter
from the membrane.

7.2 Battery
7.2.1 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 ad-
equate for operation of the product. The battery is fully depleted.
7.2.2 Changing battery
NOTE
Unnecessary screwing places the water-tightness of the product, among other things,
at risk and should be avoided.
Proceed as follows to replace the batteries.
–The product is switched off.
Fig. 1: Changing battery
1. Unscrews the Phillips screws (A)and
remove the cover.
2. Carefully replace the two Mignon AA
batteries (B). Ensure that the polarity
is correct! It must be possible to insert
the batteries in the correct position
without using force.
3. The O-ring (C) must be undamaged,
clean and positioned at the intended
depth. In order to facilitate assembly
and avoid damage, a suitable grease
can be applied.
4. Fit the cover on evenly. The O-ring
must remain at the intended depth!
5. Tighten the Phillips screws (A).
The product is now ready for use again.
