Calibration Certificate
Your NTi Audio instrument has been tested during manufacture
and conforms to the specifications listed in “Technical Data”.
The XL2 combination with the appropriate measurement mi-
crophone forms a precise class 1 or class 2 sound level meter
in accordance with the standards and configurations listed in
“Technical Data”.
You may order a manufacturer calibration certificate of your
new instrument at the local NTi Audio partner either with or
any time after the purchase of the instrument. The certificate
lists the individual instrument data with serial number recorded
prior to the shipment.
NTi Audio recommends annual calibration of the products start-
ing one year after the purchase. The calibration provides docu-
mented and traceable measurement accuracy and confirms
that your NTi Audio product meets or exceeds the published
specifications. The calibration and adjustment procedures fol-
low the documentation and traceability requirements of the
EN ISO / IEC 17025 standard.
