Messunsicherheit

Uncertainty of measurement

Angegeben ist die erweiterte Messunsicherheit, die sich aus der Standardmessunsicherheit durch Multiplikation mit

dem Erweiterungsfaktor k = 2 ergibt. Sie wurde gemäß DAkkS–DKD–3 ermittelt. Der Wert der Messgröße liegt mit einer

Wahrscheinlichkeit von 95 % im zugeordneten Werteintervall.

The uncertainty stated is the expanded uncertainty obtained by multiplying the standard uncertainty by the coverage factor k = 2. It has

been determined in accordance with DAkks–DKD–3. The value of the measurand lies within the assigned range of values with a

probability of 95%.

Die Genauigkeit des Gerätes beträgt 0,0090 bar

The accuracy of the device is 0,0090 bar

4.2.8 Uncertainty of measurement (optional)

The evaluation of the measurement uncertainty can be activated via the database

(see chapter 6.4.1 “Cal”). First, the mean values are calculated by means of a zero

adjustment in accordance with DKD-R 6-1. The corresponding measuring deviation

results from “mean value - measuring deviation”. Repeatability, hysteresis and

measurement uncertainty are also calculated in accordance with DKD-R 6-1. During

their calculation, all entries from the creation process are used.

In addition, the note from DKD-R 6-1 is listed below the table. The graphical representa-

tion is optional, too, and can be activated via the database (see chapter 6.4.1 “Cal”)

The nal assessment of the instrument´s accuracy is the biggest calculated “measuring

deviation + measurement uncertainty”.
