2.4 Intended use
_
_
_
The device measures the absolute pressure in the air, clean water or in non-
corrosive/non-ionising gases. A direct measurement of the environmental pressure can
take place or the measurement pressure is taken with a suitable hose connected to the
port. Relative measurements can also be conducted with the integrated special func-
tion NVLL.
Applications include:
G 1111
G 1114
Barometric measurements (e.g. weather)
Barometric measurements (e.g. weather)
Vacuum measurements (down to 0.0 hPa
abs., negative pressure via hose or even
with complete device evacuation)
Vacuum measurements (down to 0 hPa
abs., negative pressure via hose or even
with complete device evacuation)
Pneumatic measurements (up to 14000
hPa abs. or 14 bar abs.)
The pressure connection is made at the supplied interchangeable pressure connection
ports with suitable hoses - 4 different connection options are available as standard,
many other connection options can be used easily and reliable with G 1/8 adapters.
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 connections and
be protected from dirt.
_
NOTE
Complete evacuation see Vacuum measurements [page 13].

5 Measurement Basics
5.1 Vacuum measurements
The device is especially suitable to measure rough vacuum via the pressure port very
fast. But if the complete device is evacuated the following has to be considered:
CAUTION
Damage possible by fast complete evacuation!
Due to the water tight construction a complete evacuation of the device may degrade
water protection. The keypad/display screen may break loose. If the device should still
be used for this application, the following options are available:
–Remove the o-ring of the battery compartment! The Instrument then is no more
water protected! Changing battery.
–Specialized variants G 1111-VAC!
5.2 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.
5.2.1 NVLL Tare function
The special function FVNC NVLL has been selected in the configuration menu.
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.
NOTE
The tare function is independent of the zero point correction accessible via the adjust-
ment menu.

5.2.2 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.
_
By pressing and holding the Function key for 2 s the special function can be deactivat-
ed. END FVNC appears in the display.
_
If the tare function is active when calling up the special function AVR, it can be reset by
pressing the function key for 4 seconds. In order to reactivate tare, the special function
must be changed in the configuration menu.

5.3 Pressure Connection
NOTE
Suitable hoses must be used for vacuum measurements, silicon is suitable as a hose
material due to the low rigidity!
_
CAUTION
Air pressure at port variant UT!
With higher pressures greater than 1 bar, the hoses must be secured to prevent
unintended loosening. Suitable GDZ hose clamps are used for this purpose.
–6x1 mm PVC (GDZ-01) up to 5 bar rel., vacuum-suitable!
–6x1 mm PE (GDZ-02) up to 10 bar rel., vacuum-suitable!
–6x1 mm PUR (GDZ-03) up to 9 bar rel., vacuum-suitable!
5.3.1 Replacement of pressure hoses
The pressure connections are screwed into the product with a standard G 1/8 inch
thread with end seal. All common pressure connections with this design can be con-
nected.
NOTE
Use a suitable tool for tightening and observe the maximum torque of 2 Nm!

Description
.. - UT
Universal hose connection for 6 x 1 mm (4 mm in-
side) and 8 x 1 mm (6 mm inside) hoses.
The universal hose connection is suitable for plastic and
silicon hoses with an outer diameter of 6 mm, for which
purpose the hoses are simply connected to the upper
part. Rubber/silicon hoses with a larger diameter (e.g. 8
mm) can also be connected. They are fit on the lower
part for this purpose.
.. - QC6
Quick-Connect for Ø 6 mm hoses.
The practical quick-change connection is only suitable for
plastic hoses with 6 mm outer diameter. The hose end
must be clean and undamaged for connection. It is fit by
simply pushing it in until the mechanical stop is reached.
It is disconnected by simultaneously pressing the ring on
the upper end of the connection and pulling the hose.
.. - ST6
Screw connection for 6 x 1 mm (Ø 4 mm inside)
plastic hoses.
The secure screw connection is only suitable for plastic
hoses with 6 mm outer diameter (Ø 4 mm inside). The
hose end must be clean and undamaged for connection.
The union nut must be loosened before connection. Then
the hose is pushed onto the hose nipple up to the me-
chanical stop. The union nut is hand-tightened to secure
the connection. Disconnection takes place by loosening
the union nut and pulling on the hose.
.. - MCM
MCM mini-quick-coupler plug connector.
Compatible quick-couplers with nominal width 2.7 mm
can be used:

NOTE
Pressure connections must be protected from soiling.
6.2 Battery
6.2.1 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
adequate for operation of the device. The battery is fully depleted.
6.2.2 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 1111 / G 1114
18 / 22 B-H88.0.1X.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.
