PERIODIC VERIFICATION
The NECTOR is tested and adjusted at the factory as attested by the "calibration report" included
in this package.
When it is in service, its periodic verification is necessary to ensure the reliability of the records as
established by
UNI EN12830 and in accordance with UNI EN13486 .
Verification is also necessary if the operating temperature deviates significantly from the test
temperature reported in the calibration report.
The
recommended verification is annual and can be carried out in the following ways:
•
At an approved centre for the calibration of instruments: ACCREDIA centres for Italy
(www.accredia.it); for other European countries consult the website with the list of centres
authorised to verify the measuring instruments of the country concerned.
•
For direct comparison using a measuring device, periodically checked with a multimeter and
thermometer that are ACCREDIA tested and certified.
VERIFICATION RESULTS.
The Datalogger contained in the NECTOR series panels has a precision class of 1 so:
•
If the difference between the value measured by the Datalogger and the reference value is
between ±1°C, the verification is POSITIVE .
•
If the difference between the value measured by the Datalogger and the reference value is
greater than +1°C or less than -1°C, the verification is NEGATIVE .
NB: All results of the verification must be recorded and kept.
If the verification fails, expert personnel can adjust the instrument on site by direct comparison with
a digital reader and sample probe with a valid ACCREDIA calibration certificate. Contact Pego
Support for the procedure to be followed.
