Sensors calibration during the performace period

Hi Agata, This is a great question, sorry for the delayed response! The intent of that requirement is to confirm that the sensors were working properly during the performance period, so a maintenance plan and confirmation of the manufacturer's recommendations is a good approach if sensors don't need to be calibrated yet. I would recommend adding the date of sensor installation and the date of required calibration in the maintenance plan, and uploading the equipment manual or other documentation showing the manufacturer's recommendations.
