First calibration
Determination of the actual measurement deviation of the calibration item.
DAkkS Calibration
Accredited calibrations for our current and voltage measurement systems, traceable to national standards.
Scope
DAkkS-accredited calibrations (opens in a new tab) guarantee accurate and reliable measurement results that are traceable to national standards.
We offer these calibrations according to DIN EN ISO/IEC 17025 (opens in a new tab) for the following products. The recommended calibration interval is 24 months.
What is our procedure?
Adjustment
Adjustment of the calibration item.
Second calibration
Determination of the measurement deviation of the calibration item after adjustment.
Recalibration
During recalibration, your CMM or MesSy is calibrated, adjusted and calibrated again. You receive a calibration certificate with the measurement results before adjustment and the measurement results after it. This way, you can keep track of both the previous and the current accuracy.
If your device must not be adjusted during recalibration, this must be explicitly noted when ordering.
New device
A new CMM or MesSy is adjusted before delivery. You receive a calibration certificate with the measurement results after adjustment.

Decision rule
The rule assesses measured values taking the extended measurement uncertainty into account. The example shows a calibration with a nominal value of 10 A, a tolerance of 0.1 A and a calculated measurement uncertainty of 0.004 A.
- Nominal value
- Value measured by the standard.
- Measured value
- Value measured by the calibration item.
- Extended measurement uncertainty
- Measure of the dispersion caused by the measuring procedure, the standard and the calibration item.
- Tolerance
- Maximum permissible deviation from the nominal value according to manufacturer specifications.
Labeling in the calibration certificate
- The measured value is within the tolerance: none
- The measured value is within the tolerance with a probability of 50 % to 95 %: ?
- The measured value is outside the tolerance with a probability of more than 50 %: X
