Research and Calibration Laboratory of SONEL SA offers calibration of the following instru-
ments used for electrical/non-electrical measurements:
-
meters for electrical protective measurements: insulation resistance, impedance and re-
sistance of short-circuit loops, earthing resistances and earth resistivity, RCD parameters
and multi-functional meters that perform the above functions,
-
electrical safety meters,
-
multimeters,
-
power quality analysers,
-
meters for measuring low resistance values,
-
infra-red cameras,
-
pyrometers,
-
luxmeters.
In addition, the Laboratory performs voltage, current and resistance calibration.
A calibration certificate is a document confirming compliance of parameters declared
by the manufacturer of tested device with national standards, specifying the measurement un-
certainty.
Pursuant to standard
EN ISO 10012:2003
"Measurement management systems
—
Requirements for measurement processes and measuring equipment", SONEL S.A. recom-
mends for its instruments to be periodically tested, observing the interval of
13 months
.
For new devices with calibration certificates, the next metrological inspection (calibra-
tion) is recommended within
13 months
from the date of purchase, but not later than
19 months
from the date of manufacture.
Note:
In case of instruments used for tests related to the protection against electric shock,
the person performing measurements should have complete confidence in the effi
ciency of operated apparatus. Measurements carried out with malfunctioning meter
may cause wrong assessment of tested equipment in terms of its protection features
