Hello, the equipment came with a certificated paper of conformity or similar? Thanks

My unit did not include any form of certification. Hope this helps.

I am not interested in a Cert of conformity, does the unit come with a calibration certificate?

Hi, the unit doesn't come with calibration certificate, we can do the calibration certificate if you need but with extra cost. Please send email to us if you need to do the calibration certificate, we will quote you the price.

Hi at what distance from which point of the device should SPL be measured?

As noted, the level produced depends the VOLUME of the calibrator CHAMBER, hence how well the microphone fits into it. There is a small "stop" at the base of each microphone adapter. With just the microphone adapter in place and no microphone, it's very soft even close to your ear. 1. Insert the microphone to the point that it stops 2. Turn on the calibrator to the required level, 94 dB is the more common 3. Set the meter to "A" weighting 3. Adjust your meter as appropriate 4. Repeat for the second level and with both "A" and "C" weighting if the meter has both. Make notes of any differences for future reference.

On the digital sound level meter calibrator nd9 is there any way i can get a users manual emailed to me?
