Calibration simulation
It is possible to simulate a calibration table by filling in all the fields manually.
Program the calibration Characteristics as usual.
The simulation starts by pressing the Start button highlighted in green, the program
automatically calculates the strength to be controlled by dividing the maximum capacity of the
device being calibrated by the number of steps to be performed.
Press Stop Button
Insert manually the measured values in the table.
At the end press Calculate to calculate the errors and uncertainties.
ERRORS and UNCERTAINTIES CALCULATION
Average Reading (
F
= ((sum of the reading point in each series) / (n°of series))

Reading Error e
: it is calculated for each measurement point:

Expanded Uncertainty (U): it is calculated keep in count all the standard uncertainties for
each measurement point : Resolution, Repeteability and Reference Instrument Uncertainty
U = k*SQR((U
where:
U
= Uncertainty due to the relative resolution
res
U
= Uncertainty due to the repeatibility
rep
U
= Uncertainty due to the reference instrument
