10 Advanced functions
10.1 Setting the calibration parameters
The XPT800 sound level meter, with the standard transduction chain consisting of the MP800 preampli-
fier and model MP800 class 1 free-field microphone, is adjusted at the factory and delivered calibrated.
Adjustment with a class 1 sound calibrator should be carried out periodically, normally before and after
each measurement session, to ensure the validity of the measurements made by the sound level meter,
as the sensitivity of the microphone and the response of the electronic circuits may vary slightly over
time or may be affected by environmental conditions such as temperature, atmospheric pressure and
humidity. In addition, XPT800 has an internal compensation function for environmental conditions cor-
rections.
10.1.1 Setup
The instrument allows settings of the following parameters:
•
Acoustic Field corrections;
•
Windscreen and Outdoor microphone protection corrections (Shield correction);
•
Emission level of sound calibrator used (Level);
•
Calibration mode, manual or automatic.
To setup the calibration parameters of the instrument:
1
In the ICON MENU, press the SYS-FUNC icon to access the
system and measure configuration menus.
2
Access the CALIBRATION and SETUP pages in succession.
3
Set the desired parameters.
Acoustic field
With the supplied MC800 microphone, which has a frequency response optimized for "Free Field"
(FF), if the parameter is set to "Free Field" (FF), correction is applied accordingly. Correction by ran-
dom incidence can be enabled by setting the parameter to "Random Incidence" (RI). This setting is
necessary for surveying in accordance with ANSI standards. For example, in case you choose a mi-
crophone with frequency response optimized for "diffuse field," the normal setting is "Random Inci-
dence" (RI). You can enable correction for making free-field measurements by setting the parameter
to "Free Field" (FF). This setting is necessary for measurements in accordance with IEC standards.
Correction applied for the use of WS90 or WSO windscreens (Shield correction)
Allows the sound level meter's frequency response to be corrected when either the windscreen
WS90, supplied with the sound level meter, or the outdoor protection kit WSO is used. When this pa-
rameter is set to WS90, WSO the sound level meter's frequency response is corrected for the pres-
