Calibrate your instruments to —
- Determine the accuracy of the instrument readings.
- Ensure your readings stay consistent with other measurements.
- Establish the reliability of the instrument.
Uncertainty: How accurate are your measurements?
A measurement with a stated uncertainty can be compared to others. Measurements are traceable when they can be related to a recognised measurement system through an unbroken chain of comparisons, each with stated uncertainties.
Reliability: Can I trust the instrument?
A calibration certificate will be issued only if an instrument is found to be reliable and will satisfy its intended purpose
Achieving Traceability In Your Measurements
To make a traceable measurement, three elements are required:
- An appropriate and recognised definition of how the quantity should be measured.
- A calibrated measuring instrument.
- Competent staff capable of using the instrument and interpreting the standard or procedure.
Traceability is only ensured with the presence of these three factors in the measurement process.
