Svantek SV 104IS Noise Dosimeter Repair
The Svantek SV 104IS Noise Dosimeter is a sound level meter – the microphone is the instrument. Everything downstream is interpretation, and a microphone that has drifted or been damaged produces measurements that are wrong in a way no amount of processing recovers.
The Svantek SV 104IS Noise Dosimeter is repaired at June Company by technicians who work on this class of instrument daily, for occupational hygienists, environmental consultants, acoustic engineers, and safety departments. Every instrument is repaired at component level and verified against reference standards before it ships back, with the measured results documented.
Common Svantek SV 104IS Noise Dosimeter problems we fix
- Octave band filter faults.
- Will not accept calibration at reference level.
- Readings drifted out of tolerance – corrected and verified against reference standards.
- Display, keypad or front-panel faults.
- Battery or storage faults.
- Microphone damaged or drifted – verified against an acoustic calibrator, since the microphone carries the accuracy of every reading.
- Preamplifier faults or excessive noise floor.
- Frequency weighting network errors – A and C weighting curves drifting out of specification.
FAQs
What if it is not economical to repair? We tell you in the quote. The evaluation is free and there is no obligation to proceed.
Are the weighting filters checked? Yes. A and C weighting networks drift independently of overall level accuracy.
