2.2.1.2 Determining the accuracy/measuring uncertainty
The entries for the measuring uncertainty for the probe are determined in
accordance with GUM (Guide to the Expression of Uncertainty in
Measurement/DIN V ENV 13005). All parts that make up the measuring
uncertainty given by Testo are listed below. When comparing the measuring
uncertainty/accuracy between manufacturers, which components are
included is to be taken into account. In many cases, not all elements that
contribute to measuring uncertainty are assessed, for example if the error
contribution of the production adjustment is shown separately or not at all.
