Dear Mr. Belkacem,
We are facing a problem while using the sound level meter SERISE SE/DL. , weWe tried to follow the instructioninstructions in the user manual to get NC values as mentioned in Pageon page 90, but once we reach to select the option menu, a massage received “message appears, stating: "No data file – Option not loaded file not found”found".
On the other hand , in general we are facing discrepancy readings comparing withcompared to other devices higher /lower with the same testing condition. Therefore, socan you please if you can share with us a short video how the correct setting should be made and how can we have a final NC value on the device itself.itself?
WaitingAwaiting your support &and feedback
