18 Recalibration
The respective measuring task and the stress to which your cali-
brator 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 fre-
quently used in field applications, combined with transport stress
and great temperature fluctuations, we recommend a relatively
short calibration interval of 1 year. If your calibrator 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 rela-
tion 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 calibrator calibrated regularly, you fulfill the require-
ments of a quality management system per DIN EN ISO 9001.
* Verification of specifications or adjustment services are not part of the
calibration. For products from our factory, however, any necessary ad-
justment is frequently performed and the observance of the relevant
specification is confirmed.
