G 1114 Safety | 2
B-H88.0.14.DB2-1.0 7 / 28
The G 1114 measures the absolute pressure in the air, clean water or in non-corros-
ive/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:
– 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.
_
NOTE
Complete evacuation see Vacuum measurements [}p.16].
2.5 Qualified personnel
_
For commissioning, operation and maintenance, the relevant personnel must have ad-
equate 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.

5.2.5 Parameters of the adjustment menu
_
Description Zero point
_
– For an optimal zero point calibration, a vacuum pump and a precise reference
device 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
compensation of sensor deviations.
_
Prerequisite – The adjustment menu has been opened. See Open the adjustment menu
[}p.13].
_
Instruction 1. Select the desired parameter you would like to configure.

Formula Sensor zero point correction offset PR.OF
A zero point shift can be made for the measurement.
Displayed value = measured value – offset
Standard setting: 0.0, i.e. no correction is made.
Sensor gradient correction PR.SL
The gradient of the measurement can be influenced with this factor (factor is in %):
Displayed value = measured value * (1+Pr.SL/100)
Standard setting: 0.000, i.e. no correction is made.

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! Changing battery [}p.20].
– Specialized variants G 1111-VAC!
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
_
Prerequisite 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 set-
tings menu.
6.2.2 AVR 0:02 / AVR 0:05 / AVR 0: 10
Fast measurement with mean value over 2 s / 5 s / 10 s
Mean value mode for measurement of heavily fluctuating pressures.
_
Prerequisite In the Configuration mode, a special function AVR 0:02, AVR 0:05 or AVR 0: 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.
_

G 1114 Measurement Basics | 6
B-H88.0.14.DB2-1.0 17 / 28
Special case If the Tare function is activated when called up, this special function AVR can 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 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.
Fig.4: UT connection
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.
Fig.5: QC6 Quick-Connect
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 simul-
taneously 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.
Fig.6: ST6 screw connection
The secure screw connection is only suitable for plastic hoses with 6 mm outer dia-
meter (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.

6.8 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 va-
cuum-casting applications: In the worst case scenario, only the connection has to be
replaced.
