Pulsar Model 90 Quantifier Series Sound Level Meter Repair
The Pulsar Model 90 Quantifier Series Sound Level Meter 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.
Certified technicians at June Company service the Pulsar Model 90 Quantifier Series Sound Level Meter 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 Pulsar Model 90 Quantifier Series Sound Level Meter problems we fix
- Frequency weighting network errors – A and C weighting curves drifting out of specification.
- 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.
FAQs
It will not accept calibration at the reference level. What failed? Usually the microphone or preamplifier. Both are verified against an acoustic calibrator.
Are the weighting filters checked? Yes. A and C weighting networks drift independently of overall level accuracy.
