Svantek SVAN 979 Sound & Vibration Analyzer Repair
The Svantek SVAN 979 is a Class 1 sound and vibration level meter/analyzer — it measures noise and vibration (with the appropriate microphone or accelerometer) for environmental, occupational, and building acoustics, with octave/FFT analysis. As a precision acoustic/vibration instrument, its faults concentrate in the microphone/preamp or accelerometer input, the measurement front-end, and the display.
June Company repairs and calibrates the Svantek SVAN 979 for acoustical consultants and environmental/occupational-noise teams.
Common Svantek SVAN 979 problems we fix
- Microphone / preamp faults — the acoustic input not reading correctly, repaired so level measurements are accurate.
- Measurement accuracy out of spec — measurement-circuit drift, recalibrated against standards to hold Class 1 accuracy.
- Vibration (accelerometer) input faults — the vibration channel, restored.
- Won’t store or transfer data — memory/interface faults.
- Display, keypad, or battery faults.
FAQs
My SVAN 979 level readings are off — fixable? Yes. Microphone/preamp and measurement faults are repairable and recalibrated, then verified so it meets Class 1 accuracy, with a NIST-traceable certificate.
Are both sound and vibration verified? Yes — the relevant inputs are checked against our standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
