G 1111 Safety | 2
B-H88.0.11.DB2-0.1 7 / 28
The G 1111 measures the absolute pressure in the air 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 NVLL.
Applications include:
– Barometric measurements (weather)
– Vacuum measurements (up to 0 hPa abs., negative pressure via hose or even
with complete device evacuation)
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
must be protected from dirt and moisture.
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.
2. Adjust the desired configuration in the selected parameter with the Up button or
Down button.

_
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.
_
Outcome of an action The changed value is saved and the adjustment menu is closed. STOR appears in the
display.

16 / 28 B-H88.0.11.DB2-0.1
6 Bases for measurement
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.
Prerequisites – In the Configuration menu, the parameter value SEA.L must be set to YES.
– In the Configuration menu, the actual altitude above nautical norm must be
entered 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
_
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. Heavily fluctuating values arise particularly with dynamic pressure/
compression measurements in chimney draft tests of forced-air burners and, con-
sequently, conventional electronic manometers are not adequate for task. This special
function optimises the device for this application purpose. 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.
_
_
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.

B-H88.0.11.DB2-0.1 17 / 28
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.5: 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.
6.5 QC6 operation
Quick-Connect for Ø 6 mm hoses.
Fig.6: 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.7: ST6 screw connection

6 | Bases for measurement G 1111
18 / 28 B-H88.0.11.DB2-0.1
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.
6.7 MCM operation
Mini-quick-coupler plug connector.

Compatible quick-couplers with nominal width 2.7 mm can be used:
Fig.9: quick-coupler
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). This can prevent destruc-
tion of the product, for example, from penetration of potting compound in vacuum-
casting applications: In the worst case scenario, only the connection has to be re-
placed.

7.3 Calibration and adjustment service
7.3.1 Certificates
The certificates are categorised as ISO calibration certificates and DAkkS calibration
certificates. The purpose of the calibration is to verify the precision of the measuring
device by comparing it with a traceable reference.
NOTE
The ISO standard 9001 is applied for the iso-calibration certificates. These certificates
area affordable alternative to the DAkkS calibration certificates and provide informa-
