Metrological traceability is an important part of measurement. One of the best ways to understand an instrument’s measurement performance is to assess its accuracy. The instrument should be calibrated against an SI-traceable reference to ensure the quality of measurement data. Quality data, in turn, provides reliable information for decision-making. It's important to understand that the more calibration steps there are between the SI reference unit and the instrument, the greater the measurement uncertainty.
