ALIBRATION
The SV 104BIS dosimeter is offered with the dedicated ST 104B
MEMS microphone with ½” housing.
The
instrument is factory calibrated with the supplied microphone for the standard environmental conditions.
Because the microphone sensitivity is a function of the temperature, ambient pressure and humidity, the
absolute calibration of the measurement channel should be performed locally.
Svantek offers the SV 34B sound calibrator 114dB@1000Hz for the SV 104BIS instruments.
Note: Calibration with use of SV 34B is allowed only in a safe area.
The instrument has an automatic calibration function, which can be enabled or disabled with the use of the
Supervisor software (see Chapter
6.3.9.1 ). One of the important instrument settings is the sound pressure
level generated by the calibrator. By default, the automatic calibration is enabled, and the calibrator signal level
is set to 114 dB.
If the automatic calibration is enabled the instrument performs the acoustic calibration automatically, when the
calibrator is placed over the microphone (first remove the windscreen). The calibrator level is automatically
detected, and the calibration procedure is started.
The user simply has to press the key to confirm the calibration results. Calibration is only allowed in the
stopped mode. A sound measurement cannot be in progress while the calibration is being performed.
