13 Recommended calibration intervals
SDT recommends annual recalibration of SDT instruments and annual verification of sensors.
This periodicity is coherent with the observed long-term stability of SDT electronic equipment's.
However
-
For new equipment leaving the factory the initial period is extended to 15 months
instead of 12 (to avoid any possible discrimination between users due to transportation time,
customs clearance, etc.)
-
SDT recognizes that each customer may have their own Quality Assurance Standards and
internal requirements. If a customer has established a Quality Assurance Program that includes
a documented procedure for measurement deviations,
and if an instrument and the relevant sensor show acceptable deviations
and do not show signs of physical damage, then calibration periodicity could be extended to two
years.
-
Third party organizations having more authority (Class, or State Administrations) may
have defined their own regulations for example 6 months, or 2 years calibration interval:
by evidence, local legally applicable regulations supersede SDT rules.
For these reasons, SDT Calibration Certificates do no more mention a "calibration due date",
but simply the "last calibration date".
For user convenience, the date of the last calibration of an SDT200 or 270 instruments
can also be found in the menu screens.
