5 Using the product 5.8. Measuring Information and recommendations • Sound waves can be reflected off walls, ceilings and other objects. If not handled correctly, the measuring instrument housing and the person conducting the measurement are also disruptive factors within the sound field and can result in incorrect measurement results.
5 Using the product may be considerably higher than the actual value of the sound level displayed. Therefore, “Over” may be signalled despite the fact that a sound level within the normal framework of the respective measurement range is shown. By contrast “Under” is geared to the measured actual value and is therefore set when the lower limit of the measurement range is undershot. Carrying out a measurement 1. Switch the instrument on. 2. Set the measuring time (FAST / SLOW) 3. Set the frequency (A / C) 4.

7 testo 816-1 software To calibrate, the calibrator is screwed onto the microphone. Switch the sound level meter on and set the time weighting to “Fast” and the frequency weighting to “A”. The calibrator is then switched on by moving the switch to the middle setting (94 dB). If there is a discrepancy in the displayed value, you can adjust the sound level meter using the screwdriver included. It is then possible to check whether the second level shown by the calibrator is within the ± 0.
