The Calibration Certificate is a document specifying the relation-
ship between the standard and the instrument's indication with indi-
cation of measurement uncertainty.
According to ILAC-G24:2007 „Guidelines for the determination of
calibration intervals of measuring instruments", SONEL S.A. rec-
ommends periodical metrological inspection of the instruments it
manufactures no less frequently than once every 13 months.
For new instruments provided with the Calibration Certificate or Val-
idation Certificate at the factory, re-calibration should be performed
within 13 months from the date of purchase, however, no later than
25 months from the date of purchase.
The person performing the measurements should be absolute-
ly sure about the efficiency of the device being used. Meas-
urements made with an inefficient meter can contribute to an
incorrect assessment of the effectiveness of health protection
Measurements carried out in an accredited calibration labora-
tory (with competences confirmed by PCA), it is certain that
they were made in accordance with applicable standards, pro-
cedures, including the best reliability.
