It is important to ensure metrological accuracy, compliance with calibration error limits, function monitoring.

ISO17025 for metrological testing, OIML R139, national calibration law

Every two years at the end of the calendar year.

All-inclusive service package (coordination with the calibration authorities/conformity assessment bodies, trained personnel, traceability of the reference measuring system (RMS), maintenance and repair of the reference measuring system (RMS), issuing of certificates in accordance with ISO17025)

This usually takes 4-6 hours.

The conformity assessment is a test for compliance with legal regulations that is necessary for placing a measuring device on the market for custody transfer. Conformity assessment also plays an important role in ensuring quality, safety and environmental compatibility.

It is the responsibility of the manufacturer.

Calibration is a recurring metrological test after a legally defined calibration cycle has expired. It is important to note that calibration must be carried out in accordance with legal requirements and that the use of non-calibrated or non-compliant measuring devices can have legal consequences in many cases.

The responsibility here lies with the operator.
