CE DECLARATION
The instrument fulfills all requirements of applicable EU directives and national regulations. We confirm this with the CE mark. A calibration certificate is included with the instrument.

CALIBRATION CERTIFICATE AND CALIBRATION
A calibration certificate is included with the instrument. Use of your instrument and resultant stressing influence the instrument and lead to deviation from warranted accuracy values. In the case of strict measuring accuracy requirements, as well as in the event of severe stressing (e.g. severe climatic or mechanical stress), we recommend a relatively short calibration interval of once per year. If this is not the case, a calibration interval of 2 to 3 years is usually adequate. Please contact GMC-I Service GmbH for calibration services → “Contact, Support and Service”. A sticker with an instrument-specific guideline value for the calibration interval and information regarding the service provider is included on the instrument as an aid. Hinweis

Note
Date on Calibration Certificate / Calibration Interval Begins Upon Receipt Your instrument is furnished with a calibration certificate on which a date appears. This date may be further in the past if your instrument has been stored for some time prior to sale. The instruments are stored by the specified conditions. Drift is thus negligible for 1 year and longer storage periods are highly unusual. Consequently, the instrument’s characteristic values lie within the specifications and the first calibration interval can be determined as of the date of receipt.

DISPOSAL AND ENVIRONMENTAL PROTECTION

Proper disposal makes an important contribution to the protection of our environment and the conservation of natural resources.
