AmpManuale utente del calibratore del misuratore di suono robe SM-CAL1

1. Introduzione

IL Amprobe SM-CAL1 is a precision sound meter calibrator designed to ensure the accuracy and reliability of your sound level measurements. This device generates two fixed sound pressure levels, 94 decibels (dB) and 114 dB, at a frequency of 1,000 hertz (Hz), allowing for precise calibration of sound meters with microphones up to 1/2 inch in diameter. Regular calibration is crucial for maintaining measurement integrity and compliance with relevant standards.

This manual provides detailed instructions for the proper use, maintenance, and troubleshooting of your SM-CAL1 Sound Meter Calibrator.

2. Informazioni sulla sicurezza

Please read and understand all safety instructions before operating the SM-CAL1. Failure to follow these guidelines may result in injury or damage to the device.

• Do not expose the calibrator to extreme temperatures, humidity, or direct sunlight.
• Evitare di far cadere o sottoporre il dispositivo a forti impatti.
• Do not attempt to open or modify the calibrator. Refer all servicing to qualified personnel.
• Assicurarsi che il vano batteria sia ben chiuso durante il funzionamento.
• Smaltire le batterie secondo le normative locali.

4. Impostazione

4.1 Installazione della batteria

The SM-CAL1 comes with a 9V battery pre-installed. If replacement is needed:

1. Individuare il coperchio del vano batterie nella parte inferiore dell'unità.
2. Togliere il coperchio.
3. Connect a new 9V battery, observing correct polarity.
4. Riposizionare saldamente il coperchio del vano batteria.

4.2 Preparing for Calibration

Figura 1: Amprobe SM-CAL1 Sound Meter Calibrator. The image shows the top face of the cylindrical calibrator, featuring the 'AMPROBE' logo, 'SM-CAL1' model number, a three-position slide switch labeled '94', 'OFF', and '114' (referring to dB levels), and text indicating 'db at 1kHz', 'IEC 942 1988 CLASS 2', and 'Sound Calibrator'. A red power indicator light is also visible.

5. Funzionamento

5.1 Calibrating a Sound Meter

1. Gently insert the microphone of your sound level meter into the opening on the top of the SM-CAL1 calibrator. Ensure a snug fit to minimize sound leakage.
2. Select the desired calibration level using the slide switch on the calibrator:
   • Slide to '94' for a 94 dB signal.
   • Slide to '114' for a 114 dB signal.
3. Observe the reading on your sound level meter. Adjust your sound meter's calibration settings until its display matches the selected output level of the SM-CAL1 (either 94 dB or 114 dB). Refer to your sound meter's user manual for specific calibration adjustment procedures.
4. Once calibration is complete, slide the switch to 'OFF' to conserve battery life.
5. Carefully remove the sound meter's microphone from the calibrator.

5.2 Indicazione di batteria scarica

The SM-CAL1 is equipped with a low-battery indicator. When the battery voltage drops below a certain level, the indicator light will dim or not illuminate, signaling that the 9V battery needs to be replaced.

6. Manutenzione

6.1 Pulizia

To clean the exterior of the calibrator, use a soft, dry cloth. Do not use abrasive cleaners or solvents, as these may damage the casing o componenti interni.

6.2 Conservazione

When not in use, store the SM-CAL1 in a cool, dry place, away from direct sunlight and extreme temperatures. If storing for extended periods, it is recommended to remove the 9V battery to prevent leakage.

6.3 Recalibration of the SM-CAL1

While the SM-CAL1 is designed for stable output, periodic verification of its accuracy by a certified calibration laboratory is recommended to ensure continued compliance with standards and optimal performance. The frequency of such recalibration depends on usage and regulatory requirements.
