Why regular calibration?
Calibration certificates are increasingly required in
tendering procedures for electric shock protection. They provide protection by
proving that the used instrument is working correctly and performed
measurements correctly. Calibration certificates are also required by insurers
to maintain good technical condition of protection devices. Regular calibration
of measuring instruments, following manufacturers' recommendations, ensures the
working order of the meters. An up-to-date calibration certificate should be
the domain of a professional and responsible electrician.
A calibration certificate contains designed errors that can
be included in a measurement procedure. These errors can be corrected during
measurement, allowing for the update of measurement procedures. The correct
measuring range starts from 0.13 ? up to 1999 ?. Analyzing results from cyclic
calibrations provides important data for determining calibration validity
periods. The user bears full responsibility for the efficiency of the used
instruments and should calibrate in a laboratory. Calibration also reduces
losses and costs, as demonstrated by a thermal imaging camera with an updated
calibration certificate.
