The Calibration Certificate is a document that presents a relation
between the calibration standard of known accuracy and meter in-
dications with associated measurement uncertainties. The calibra-
tion standards are normally traceable to the national standard held
by the National Metrological Institute.
According to ILAC-
G24 „Guidelines for determination of calibration
intervals of measuring instruments”, SONEL S.A. recommends pe-
riodical metrological inspection of the instruments it manufactures
no less frequently than once every 12 months.
For new instruments provided with the Calibration Certificate or Val-
idation Certificate at the factory, re-calibration should be performed
within 12 months from the date of purchase, however, no later than
24 months from the date of purchase.
ATTENTION!
The person performing the measurements should be abso-
lutely sure about the efficiency of the device being used.
Measurements made with an inefficient meter can contrib-
ute to an incorrect assessment of the effectiveness of
health protection and even human life.
