Factory Calibration

Calibration is the documented comparison of a measurement device (Device Under Test or DUT) with a traceable reference. The reference, often called a calibrator, serves as the gold standard for accuracy. During calibration, the DUT’s measurement result is compared to the reference’s output. The reference is meticulously calibrated and maintained to ensure its accuracy. Furthermore, the reference’s accuracy is traceable to a national or international standard held by a metrology body. This ensures consistency and reliability across different laboratories and industries.

Calibration helps ensure the accuracy and reliability of measurements and tests. Therefore, it is an essential factor for improving the efficiency, compliance, safety, and sustainability of any operation. The accuracy of each individual instrument changes over its product lifetime, making regular calibration essential.

Calibration frequency depends on several factors, including the type of instrument, its use, application, and industry standards. Establishing calibration intervals involves a thoughtful approach to ensure accurate measurements while avoiding unnecessary downtime and cost. Electronic components and mechanical devices exhibit drift over time due to environmental conditions. To ensure your OMICRON device consistently operates within published specifications and tolerances, we recommend that it be calibrated regularly.

Calibration
Calibration involves measuring physical quantities and comparing the test object’s measurement results with a suitable and traceable reference measuring instrument under defined, reproducible conditions.

Verification
Verification is the comparison of a device’s measurement results collected during calibration with limit values, for example, published tolerances and the interpretation of the results. This means that a statement is made about whether the device is still within the manufacturer’s specified tolerance range.

Adjustment
During adjustment, the deviation between the test instrument’s measured values and a reference instrument is reduced to a minimum or brought back within a defined tolerance range. This requires a test instrument intervention.

During our factory calibration, the device is fully tested and calibrated. Adjustment may be included depending on the service location and device type. All relevant, technical limit values are checked during an automated test procedure in a climate-controlled environment. 

OMICRON has been ISO 9001-certified since 1998. As part of the requirements, we use measuring instruments that are sufficiently precise for quality assurance.  

The OMICRON Calibrations service has established a globally recognized, state-accredited ISO/IEC 17025 calibration laboratory that meets the highest international standards. Requests can also be made for well-founded interpretations of measurement results and estimates regarding the definition of extended calibration intervals.

We not only set highest standards during the development of our products but also for our calibration solutions. Our extensive experience calibrating our devices enables us to select all critical test points to ensure full functionality. 

Third-party laboratories are limited to verifying the input and output variables of current or voltage. By contrast, our capabilities extend beyond these parameters, also enabling us to calibrate switch-off limits and frequency response. Furthermore, our fully automated test procedures allow for better comparability between calibrations than manual calibrations, where different operators have performed the procedure.

We routinely calibrate all our test equipment at independent laboratories to maintain expected tolerances. We also use “golden devices” to verify consistency across test systems. This involves calibrating the same golden device on different towers and comparing the results. Additionally, we validate results with an independent ISO/IEC 17025-accredited laboratory.

During factory calibration your product is brought into the best possible condition. This service is for you if you want to ensure reliability and precision, or if you want your devices calibrated for compliance reasons. It is the ideal choice for routine checks and regular calibration intervals, and it is our standard offer.

The ISO/IEC 17025 calibration is for special requirements. If defined measurement uncertainty and traceability are important to you, this is the right choice. In some countries and industries, an ISO/IEC 17025 calibration is mandatory. If you only want an as-found calibration only without any adjustment to monitor drift, you should also opt for the ISO/IEC 17025 calibration. Additionally, if you want consulting services on your calibration interval, the OMICRON Calibrations team is the right partner for you.

1. AsFound: Initial data is recorded during calibration.
2. Adjustment/Repair: This involves a product intervention for bringing limit values back within the defined tolerance range. If needed, this is based on AsFound data.
3. AsLeft: Data is recorded after adjustments.
4. FoundLeft: This refers to situations where  an adjustment is not wanted or needed. In this case, AsFound data is the same as AsLeft.

Many issues can be solved at your nearest service center. Our calibration capabilities and service centers are continually expanding. If your issue cannot be resolved at a local service center or with a service partner, devices need to be sent back to OMICRON in Austria. 

The warranty and guarantee period shall be 24 months from the date of product handover to the customer, unless explicitly agreed otherwise in writing. This period is limited to six months for repairs and hardware modules.
