#Smart tool level calibration full
Full air conditioning is not normally required for calibration at this level, as it is very expensive, but sensible precautions should be taken to guard the area from extremes of heat or cold, and also good standards of cleanliness should be maintained.
The level of environmental control required during calibration should be considered carefully with due regard to what level of accuracy is required in the calibration procedure, but should not be overspecified as this will lead to unnecessary expense. This will enable better environmental control to be applied in the calibration area and will also offer better protection against unauthorized handling or use of the calibration instruments. As far as possible this should take the form of a separate room, rather than a sectioned-off area in a room used for other purposes as well. This will normally mean setting aside a particular place within the Instrumentation Department of a Company where all calibration operations take place and where all instruments used for calibration are kept. To ensure that these conditions are met, the calibration function must be managed and executed in a professional manner. Standard calibration instruments must be totally separate.
Proper provision for process instrument failures must be made by keeping a spare set of process instruments. Most particularly, it must not be regarded as a spare instrument that can be used for process measurements if the instrument normally used for that purpose breaks down.
