The words “reading” and “measurement” get used synonymously. SSPC-PA 2 makes an interesting distinction by defining a “reading” as a single instrument result and a “measurement” as the average of a series of readings. A single reading should seldom be trusted whether you are making a thickness determination or adjusting to a shim.
