Pascal Link - Test Report Software
It is the most user friendly program on the market. It has
an immediate impact on the calibration operations
allowing configuration, in A4 format, of the calibration
reports and/or certificates according to users standards.
Automatic calibration and set-up data transfer (over
RS 232 serial interface) makes Pascal Link the safer
software system to support any calibration
procedure according to ISO 9000 standards..

How to compare specifications
Accuracy or Uncertainty
Usually the SCANDURA declarations concerning the metrological aspects involve the uncertainty approach.
Since some ambits seem to prefer a declaration that involves the word “Accuracy” instead of the “Uncertainty”, we have
decided to report this value into our specifications also, giving to the customer the possibility to understand the difference.
Actually, in a different way from what it happens for the “Uncertainty”, that it is well defined, the “Accuracy” it is not: in
details, referring to the international rules, the term “ accuracy” is just a qualitative term ( e.g. you can say that a
measurement is “accurate” or “not accurate”) instead the “Uncertainty” is a quantitative term. Accordingly when a “plus or
minus” figure is quoted, it should be only an “Uncertainty”, not an “Accuracy”: in spite of this fact, many technical
datasheets report the term “Accuracy” followed by a number. In general it’s possible to read that the “Accuracy” includes:
non-linearity, hysteresis and non-repeatability. so, under the name “Accuracy”, we have reported the contribution of these
components to the Total Extended Uncertainty. In the same way, under the name “Uncertainty” the Total Extended
Uncertainty has been reported: this value includes all the components of the Uncertainty and has been given with a
confidence level of around 95 %. Only to give an idea on how these values have been carried out we report here below the
components of the “Accuracy” and those of the “Uncertainty” taken into consideration.
Accuracy:
- hysteresis
- non-repeatability
- non-linearity
Uncertainty:
-
hysteresis
non-repeatability
non-linearity
instrument resolution
indication error
uncertainty of the reference
instrument used to measure the
components above-mentioned
The methods to calculate the contribution of these components are in accordance to the international rules: ISO GUM
“Guide to Expression of Uncertainty in Measurement”, ISO ENV 13005.
For the declaration of the “Accuracy” see: ISA 51.1
Temperature compensation
As the instrument can be used in different environmental conditions, the correction of the indication error due to the
temperature effect has be done separately.
For the pressure parameters:
temperature effect: 0,002 % rdg/|t – tc| from 0 °C to 50 °C
where:
tc is the calibration temperature equal 20 °C;
t is the ambient temperature;
% rdg means that the value is reported in percent of the measuring point reading (eg.: 10 bar).
E.g.: if the instrument will be used at a temperature t equal to 20 °C this temperature error contribution will be equal zero.
Percent of reading or full scale
The “Accuracy” such as the “Uncertainty” can be declared in percentage of the reading (% rdg) or in percentage of the full
scale (% fs).
For the pressure parameters (e.g.: for strain gauge pressure sensors) we declare in percent of the full scale. Why? In this case,
in fact, the hysteresis contribution, that is an important value in the calculation process, strictly depends on the maximum
pressure point and, to be conservative, we assume for this value the full scale.
Specifications are subject to change without notice.
