Calibration in the factory
To order DAkkS calibration of the CVC 3000 detect pressure transducer,
order number: .............................................................................. 900217
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 stan-
dards (accreditation number D-K-15154-01). The DAkkS is signatory to
the multilateral agreements of the European cooperation for Accredita-
tion (EA) and of the International Laboratory Accreditation 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 calibration of inspection, measuring and test
equipment at specied intervals.
- To document that the vacuum gauges calibrated are traceable to na-
tional 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).
Attention: Never use a pointed or sharp-edged tool to
clean the pressure transducer.
Never touch the ceramic diaphragm of the pressure
transducer with hard objects.
➨ Fill the measurement chamber via the vacuum connection with a sol-
vent (e.g., benzene) and allow sufcient cleaning time. Observe all
regulations concerning usage and disposal of solvents!
