An instrument list provides more information on each instrument in the project P&IDs. It notes the instrument’s tag number; process signal range (the minimum and maximum values that the instrument is to be calibrated for in engineering units; this is different from the instrument design range listed in the instrument specification); specification reference (detailed instrument specifications are located elsewhere in the project specifications and are referenced by their respective specification section); and drawing reference numbers (P&ID, location, etc.).
