Whitepaper – Calibration


Reasons for a Calibration#

Nowadays it is not enough just to develop high-quality, safe and high-performance products. Evidence that products meet certain quality characteristics must be provided both internally and externally. Comparable statements are only possible with measuring equipment that exhibits traceable accuracy. This is the only way to comply with international standards such as DIN EN ISO 17025 or IATF 16949.

In addition, regular calibration ensures high data integrity and reliability of the measurement systems. Calibration is thus an important part of the maintenance of measurement hardware. Regular calibration not only saves time and money but also ensures that the customer can meet all project requirements.

Calibration Interval#

Measuring equipment is subject to continuous loss of accuracy over its lifetime due to environmental conditions and wear. Many application areas are subject to obligations to provide proof of function with defined accuracies. For example, when a measuring instrument ages and no longer meets accuracy specifications without the user's knowledge, it is possible that test results from past measurement campaigns may suddenly no longer be valid. This results in considerable costs, not to mention the failure of the measurement system. In order to achieve a certain degree of traceability and comparability, measuring instruments must be calibrated at regular intervals, depending on the measurement system, sensor technology and area of application. GeneSys recommends a calibration interval of two years for its ADMA inertial systems.

Concepts#

Calibration#

During calibration, the deviation of the measured quantities of a measuring instrument is traced back to a - usually national - standard under defined ambient conditions. The calibration result and the associated measuring uncertainty are documented in a calibration certificate.

Adjustment#

Adjustment is the setting or calibration of a measuring device to eliminate systematic error of measurement to the extent required for the intended application. Adjusting requires intervention that permanently changes the measuring device. Here, the measured value of a measuring device is set to the known value of a device under test, e.g, through comparison with a reference standard.

Systems that can be calibrated#

All systems of the ADMA family can be calibrated. In addition, GeneSys can also calibrate the measuring systems of other manufacturers. If interested, please feel free to contact us. We check if your system can be calibrated and provide you with a quotation.

Factory calibration#

Factory calibration is subject to the laboratory's self-obligation to traceability following the DIN EN ISO 17025 standard. At GeneSys, it includes an adjustment with subsequent calibration. For factory calibration, GeneSys guarantees in own obligation the traceability in conformance with standards, documented laboratory processes and expert calculations of the calibration uncertainties. This service is provided outside the scope of accreditation.

Calibration Laboratory#

GeneSys Elektronik qualifies as a DAkkS accredited calibration laboratory for the measured quantities of velocity, angular velocity and acceleration. With regular audits, the "German Accreditation Body" DAkkS guarantees accurate and reliable measurement results that are based on DIN EN ISO/IEC 17025.

Accredited Calibration#

With this calibration you will receive an accredited calibration certificate. This allows measuring instruments calibrated by GeneSys in the DAkkS-accredited scope to be further listed in a metrological traceability chain. In contrast to factory calibration, they are not subject to direct responsibility, but are proven to comply with the DIN EN ISO/IEC 17025 guideline.
