DECLARATION, CERTIFICATION, CALIBRATION
The manufacturer provides an EU declaration of conformity.
Calibration - The final metrological control - comparison with standards or working instruments - is carried out for all products. The continuity of standards and work measurement instruments is ensured within the meaning of article 5 of Law No. 505/1990 on metrology. The manufacturer offers the possibility of supplying the calibrated sensors in the laboratoryλ (according to the requirements of standard EN ISO / IEC 17025) or in an accredited laboratory.

SENSOR INSTALLATION AND MAINTENANCE Before connecting the power cable, lift the cover of the plastic connection head using a flat screwdriver. The input cable is connected to the terminals according to the wiring diagram through the loose eyelet. The recommended wire section is 0,35 to 1,5 mm2, the diameter of the circular section cable can range from 4 to 8 mm. To ensure the protection value IP 65, the grommet must be tight and the cover must be put on after connecting the input cable. If the input cable is laid near high-voltage conductors or those supplying equipment which creates a disturbing electromagnetic field (for example, equipment with inductive load), a screened cable must be used. After installation and connection of the sensor to the sequential electrical evaluation system equipment that the sensor is ready to use. The sensor does not require any particular maintenance. The device can be used in any working environment position, but the eyelet must not be directed upwards.
