OUNTING AND POSITIONING
SV 104BIS
Unless specified by local legislation, personal noise dosimeters should always be mounted on the shoulder,
circa 10 cm from the most exposed ear, with the microphone approximately a few cm above the shoulder.
SV 104BIS shape and microphone height ensures proper instrument position, see figure below.
Figure 3-6 SV 104BIS positioning
Note: The dosimeter should be mounted on conductive clothes and/or with direct touch to human
body. This assures a path to remove the accumulated electrostatic charge that could be built-up on
dosimeter.
