- Abstract:
- The laboratory of MIKES-Lahti Precision Oy has made over almost twenty years comparisons with the PTB, utilizing more than ten different force transducers. These comparisons have been made regularly every year to supervise the traceability of force. The results of these comparisons are showing different kinds of behaviours. For the traceability the most important characteristic is the stability of the sensitivity. The change of the sensitivity directly influences the measurement uncertainty and as a result affects the final uncertainty of the intercomparison. The second characteristic is the zero reading, which can indicate the change of the measurement behaviour of the transducer.
