10.6.1 Prior adjustments: Sensitivity
The module for vibration measurements adds a new option in the settings menu that allows
you to apply a different sensitivity when using both modes: “Human exposure to whole-body
vibration in buildings” and “FFT narrow band frequency analysis for vibration”. This way
allows you not to loose the microphone sensitivity adjustment.
Then selecting the option SETTINGS Î SENSITIVITY ADJUSTMENTS from the SC310
menu the next screen will appear
To adjust the microphone sensitivity, choose the MICROPHONE option
To adjust the accelerometer sensitivity, choose the ACCELEROMETER option
If you have acquired the SC310 sound level meter with the Human exposure to whole-body
vibration in buildings module included and with a
accelerometer, you should
not make any sensitivity adjusts. This already comes adjusted with the adquired
accelerometer.
If you have adquired the module after buying the SC310 and you are using a
accelerometer, follow the next steps to adjust the sensitivity from the accelerometer.
1) Select the option SETTINGS Î SENSITIVITY ADJUSTMENTS Î
ACCELEROMETER from the SC310 menu.
2) It appears the next screen:
3) Select the model of the accelerometer. In this way the sensitivity of the SC310 will be
adjust to the nominal sensitivity of the selected accelerometer: AC001 Î S = 100
mV/g, AC005 Î S = 500 mV/g or AC006 Î S = 1000 mV/g
If you have the CV111 CESVA calibrator for vibration you can adjust the sensitivity value in a
more precise way by following the next steps.
1) Couple the SC310 + accelerometer to the calibrator for vibration (screwing it or using
a magnet).
2) Turn on the calibrator and check the battery status (if the battery condition led is
flashing green then the battery is sufficiently charged but, if the battery condition led
is flashing red then the battery is discharged).
