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 final assessment of the instrument´s accuracy is the biggest calculated “measuring
deviation + measurement uncertainty”.
