11� REGULATORY AUDIT
New devices are delivered with a certificate of adjustment. This document indicates the values obtained during
adjustment and certifies that the sensor has been adjusted, following an internal procedure, on a calibration bench
on which a standard sensor is connected to the international standard calibration.
Tractel
recommends an annual metrological check of each device.
