Note
After updating the software, reinstall the desired lan-
guage to the test instrument as well, even if the language
will not be changed. This assures that all of the additional
functions included in the update are correctly displayed.
10.8 Recalibration
The respective measuring task and the stress to which your mea-
suring instrument is subjected affect the ageing of the compo-
nents 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 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 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 measuring instrument calibrated regularly, you ful-
fill the requirements 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 adjustment is frequently
performed and the observance of the relevant specification is confirmed.
10.9 Device Return and Environmentally Compatible Disposal
