N
G
E
R
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
This product does not belong in children's hands!
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
in the operating manual.
The product is not suitable for use in explosion-prone areas!
The product must not be used for diagnostic or other medical purposes on pa-
tients!
For measurements requiring devices that are subject to authorisation or special
approvals, this product is not a substitute for such products and can only be used
as an aid in preparatory or comparison measurements!

2.4 Intended use
The G 1114 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
function .
Applications include:
Barometric measurements (e.g. weather)
Vacuum measurements (up 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.

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.

Zero point
For an optimal zero point calibration, a vacuum pump and a precise reference de-
vice are needed.
The zero point correction is used together with the gradient correction primarily for
compensation of sensor deviations. The entry takes place in the display unit.
Gradient
A pressure reference is necessary for the gradient adjustment, e.g. in the form of a
pressure source and a reference display device.
The gradient correction is used together with the zero point correction primarily for

6 Measurement Basics
6.1 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! .
Specialized variants G 1111-VAC!
6.2 Special functions
With the special functions that can be selected via the , 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 for 4 s.
The special function has been selected in the configuration menu.
The display can be zeroed by pressing the for 4 s. If the tare function is
activated, blinks in the lower display. The tare function can be reset by pressing
the again for 4 s.
NOTE
The tare function is independent of the zero point correction accessible via the set-
tings menu.
Fast measurement with mean value over 2 s / 5 s / 10 s
Mean value mode for measurement of heavily fluctuating pressures.
In the , a special function V : , V : or V : has been
selected.
By pressing and holding the 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 V can be reset
by pressing and holding the for 4 s. In order to reactivate the Tare, the
special function must be switched in the configuration menu.
6.3 Pressure connections
NOTE
Suitable hoses must be used for vacuum measurements, silicon is suitable as a hose
material due to the low rigidity.
6.4 UT operation
Universal hose connection for 6 x 1 mm (4 mm inside) 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.

CAUTION
Air pressure!
With higher pressures greater than 1 bar, the hoses must be secured to prevent unin-
tended 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!
6.5 QC6 operation
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 simulta-
neously pressing the ring on the upper end of the connection and pulling the hose.
6.6 ST6 operation
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 diame-
ter (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 mechanical stop. The union nut is hand-tightened to secure the
connection. Disconnection takes place by loosening the union nut and pulling on the
hose.
6.7 MCM operation
Mini-quick-coupler plug connector.
Compatible quick-couplers with nominal width 2.7 mm can be used:
6.8 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!
6.9 Protection of sensors with use of filter
membranes
The product and the sensor can be protected easy and effectively with the use of filter
membranes (e.g. adhesive membrane for UT connections, GDZ-35). This can prevent
destruction of the product, for example, from penetration of potting compound in vacu-
um-casting applications: In the worst case scenario, only the connection has to be re-
placed.
