D-16: Is each measuring item uniquely identified, calibrated or verified at a set interval against a recognised standard, and is its status visible to the person about to use it?
Your answer: Yes, evidence to hand. Your note: Everything is calibrated every year.
The note doesn't say how each item is identified, or where its calibration status is shown.
An assessor is likely to ask: Show me one of your gauges and its calibration record.
