The sound level meter calibrator<\/strong> is an instrument used to periodically verify the response of a sound level meter and, where provided for by the instrument\u2019s procedure, to adjust it using a known acoustic signal. It is useful for internal checks where it is necessary to verify that the sound level meter continues to measure the sound level correctly before a series of measurements is carried out.<\/p>\n

This acoustic calibrator<\/strong> generates two stable signals at 1000 Hz, selectable at 94 dB and 114 dB<\/strong>. The sound level meter microphone is inserted into the dedicated calibrator socket, then the required sound level is selected and the calibration procedure specified for the sound level meter in use is followed.<\/p>\n

The option to select between two sound pressure levels makes it possible to adapt the verification to operational requirements and to the characteristics of the instrument being checked. The display makes the selected signal immediately identifiable, while the compact design facilitates use during checks carried out in production departments, workshops or off-site locations.<\/p>\n

The calibrator is compatible with \u00bd\u201d and 1\u201d<\/strong> microphones thanks to the dedicated adapter. It can therefore be used with sound level meters fitted with a compatible microphone, including the SA5868P sound level meter<\/a> for noise checks on machinery, motors and systems.<\/p>\n

A check carried out with the calibrator before a measurement session helps verify the correct response of the sound level meter-microphone system and identify any differences requiring further investigation. During use, it is important to ensure proper coupling between the microphone and the calibrator socket in order to obtain stable verification conditions.<\/p>\n

Calibration report<\/a> available on request<\/strong>, to accompany the sound level meter calibrator with metrological documentation useful for internal checks and for monitoring its status over time.<\/p>\n

    FAQ – Sound level meter calibrator<\/h2>\n

    What is a sound level meter calibrator used for?<\/strong>
    \nA sound level meter calibrator generates a known, stable acoustic signal that makes it possible to verify the response of the sound level meter. It is useful before a series of measurements and during periodic instrument checks.<\/p>\n

    Which acoustic signals does the calibrator emit?<\/strong>
    \nThe calibrator emits two selectable signals: 94 dB and 114 dB, both at a frequency of 1000 Hz. The selected value depends on the verification or calibration procedure specified for the sound level meter in use.<\/p>\n

    Is the calibrator compatible with all sound level meters?<\/strong>
    \nThe calibrator can be used with sound level meters fitted with a compatible microphone. The supplied adapter allows use with \u00bd\u201d and 1\u201d microphones; before use, it is nevertheless advisable to verify that the sound level meter provides for calibration using an external acoustic signal.<\/p>\n

    How is a sound level meter calibrator used?<\/strong>
    \nThe sound level meter microphone is inserted into the dedicated calibrator cavity, ensuring that the coupling is stable. After selecting the required acoustic signal, the procedure specified by the sound level meter for verification or calibration is carried out.<\/p>\n

    When is it useful to verify a sound level meter with the calibrator?<\/strong>
    \nIt is useful to carry out a check before a measurement session, especially when the sound level meter is regularly used for internal checks, comparisons between different areas or inspections on machinery and systems.<\/p>\n

    Can altitude affect the signal emitted by the calibrator?<\/strong>
    \nAt high altitudes, the emitted sound level may decrease slightly compared with the nominal value. When the calibrator is used at altitude, the correction instructions specified for the operating conditions should be taken into account.<\/p>\n

    Is a calibration report available for the calibrator?<\/strong>
    \nYes, a calibration report is available on request.<\/p>\n","protected":false},"excerpt":{"rendered":"
