Dear customer,
Your VACUUBRAND vacuum gauge shall support you at your work for a long time without any trouble
and with full load output. Thanks to our large practical experience we attained much information how you
could add to an efcient application and to personal safety. Please read these instructions for use prior
to the initial start-up of your controller.
VACUUBRAND vacuum gauges are the result of many years of experience in construction and practi-
cal operation of these vacuum gauges combined with the latest results in material and manufacturing
technology.
Our quality maxim is the „zero fault principle“: Every vacuum gauge leaving our company, is tested in-
tensively including an endurance run. Therefore faults, even those which occur rarely, are identied and
can be eliminated immediately. The achievement of the specications after the endurance run is tested
for every device.
Every VACUUBRAND device achieves the specications.
We are committed to providing our customers with this high quality standard.
We know that the device cannot replace all of your real work and hope that our products contribute to
an effective and trouble-free realisation of your work.
Yours

Readjustment of the vacuum gauge DVR 2
➨ Press ”UP/DOWN” key and keep it pressed
while switching on.
☞The vacuum gauge switches into the adjust-
ment mode (indicated by a warning triangle).
☞The arrow at the right indicates, that the pres-
sure reading can be increased using ”UP/
DOWN” key.
➨ Press ”UP/DOWN” key to increase the read-
ing to the actual atmospheric pressure.
The equipment has been adjusted at the factory. In general, there is no need for adjustment by the user
due to the excellent longtime stability.
Depending on operation conditions, type of application and accuracy requirements, an inspection and
readjustment may become necessary.
Admit air to the vacuum gauge. Make sure that the vacuum connection at the vacuum gauge is at at-
mospheric pressure.
Attention: Determine the exact actual atmospheric pressure, e. g. by using an accurate barometer or
get accurate reading from the weather service, e. g. at the next airport, etc. (take into account the differ-
ence in altitude between e. g. airport and laboratory).
To reduce the reading:
➨ Press ”MODE” key to change the direction
of adjustment. The arrow moves to the left
indicating that the pressure reading can be
reduced.
➨ Press ”UP/DOWN” key to reduce the reading.
Evacuate the vacuum gauge to a pressure <0.5 mbar (<0.4 Torr) e. g. by applying a good rotary vane
pump.
➨ Press ”UP/DOWN” key and keep it pressed
while switching on.
☞The vacuum gauge switches into the adjust-
ment mode (indicated by a warning triangle).
☞The reading is adjusted automatically to
”zero”.
Attention: Adjustment under vacuum with a pressure higher than 0.5 mbar (0.4 Torr) reduces the ac-
curacy of measurement. If the pressure is signicantly higher than 0.5 mbar (0.4 Torr), adjustment to a
reference pressure is recommended.
➨ Press ”ON/OFF” key to conrm the adjust-
ment and to terminate the adjustment mode.

Control of measuring equipment
The VACUUBRAND DAkkS calibration laboratory is accredited by the Deutsche Akkreditierungsstelle
GmbH (national accreditation body of the Federal Republic of Germany) for the measurable variable
pressure in the pressure range from 7.5*10-4 Torr to 975 Torr (10-3 mbar to 1300 mbar) in accordance with
the general criteria for the operation of testing laboratories dened in the DIN EN ISO/IEC 17025:2000
series of standards (accreditation number D-K-15154-01). The DAkkS is signatory to the multilateral
agreements of the European cooperation for Accreditation (EA) and of the International Laboratory Ac-
creditation Cooperation (ILAC) for the mutual recognition of calibration certicates.
Rely on calibration in the VACUUBRAND calibration laboratory:
- To meet the requirements of the DIN ISO 9000ff and 10012 series of standards regarding the calibra-
tion of inspection, measuring and test equipment at specied intervals.
- To document that the vacuum gauges calibrated are traceable to national standards of the PTB
(Physikalisch-Technische Bundesanstalt; German national institute for science and technology and
the highest technical authority of the Federal Republic of Germany for the eld of metrology and
certain sectors of safety engineering).
Evacuate the vacuum gauge to an exactly known reference pressure within the range of 0 .... 20 mbar
(0 .... 15 Torr). Switch the vacuum gauge to the adjustment mode (see ”Adjustment under vacuum”).
Attention: The accuracy of the value of the reference pressure will directly affect the accuracy of the
adjustment. If the nominal ultimate vacuum of a diaphragm pump is used as ”reference” vacuum, the ac-
curacy of the adjustment of the vacuum gauge might be doubtful. The diaphragm pump may not achieve
the specied value due to condensate, poor state, failure of the valves or the diaphragm.
➨ Press ”UP/DOWN” key to adjust the reading
from ”0” (”zero”) to the actual reference pres-
sure in the vacuum line in the range of 0 to 20
mbar (0 to 15 Torr).
➨ Press ”ON/OFF” key to conrm the adjust-
ment and to terminate the adjustment mode.
