16 Recalibration
The respective measuring task and the stress to which your
measuring instrument is subjected affect the ageing of the
components and may result in deviations from the
guaranteed accuracy.
If high measuring accuracy is required and the instrument is
frequently used in field applications, combined with transport
stress and great temperature fluctuations, we recommend a
relatively short calibration interval of 1 year. If your measuring
instrument is mainly used in the laboratory and indoors
without being exposed to any major climatic or mechanical
stress, a calibration interval of 2-3 years is usually sufficient.
During recalibration* in an accredited calibration laboratory
(DIN EN ISO/IEC 17025) the deviations of your instrument in
relation to traceable standards are measured and
documented. The deviations determined in the process are
used for correction of the readings during subsequent
application.
We are pleased to perform DAkkS or factory calibrations for
you in our calibration laboratory. Please visit our website at
www.gossenmetrawatt.com ( Company  DAkkS
Calibration Center or  FAQs  Calibration questions and
answers).
By having your measuring instrument calibrated regularly, you
fulfill the requirements of a quality management system per
DIN EN ISO 9001.

Attention!
!
Please observe the maximum values of the electrical safety
of the device.
In conformity with standard DIN EN 61010-031,
measurements in an environment according to
measuring category III and IV may only be performed
with the safety cap applied to the test probe of the
measurement cable.
For establishing contact in 4 mm jacks you have to remove
the safety cap by levering out the snap lock of the safety cap
with another sharp object (e.g. the second test probe).
*
Verification of specifications or adjustment services are not part of the
calibration. For products from our factory, however, any necessary adjustment
is frequently performed and the observance of the relevant specification is
confirmed.
