5.3 Recalibration
The measuring tasks performed with your instrument, and the
stressing it’s subjected to, influence aging of its components and
may result in deviation from the specified levels of accuracy.
In the case of strict measuring accuracy requirements, as well as
in the event of use at construction sites with frequent stress due
to transport and considerable temperature fluctuation, we recom-
mend a relatively short calibration interval of once per year. If your
instrument is used primarily in the laboratory and indoors without
considerable climatic or mechanical stressing, a calibration inter-
val of once every 2 to 3 years is sufficient as a rule.
During recalibration at an accredited calibration laboratory
(DIN EN ISO/IEC 17025), deviations from traceable standards
demonstrated by your measuring instrument are documented.
Ascertained deviations are used to correct display values during
later use of the instrument.
We would be happy to perform DAkkS or factory calibration for
you at our calibration laboratory. Further information is available at
our website:
www.gossenmetrawatt.com ( Company  DAkkS Calibration
Center or  FAQs  General – Calibration Questions and
Answers).
Recalibration of your instrument at regular intervals is essential for
the fulfillment of requirements according to quality management
systems per DIN EN ISO 9001.
* Examination of the specification, as well as adjustment, are not included in calibra-
tion. However, in the case of our own products, any required adjustment is per-
formed and adherence to the specification is confirmed.
