Our skilled technicians are equipped with the expertise, diagnostic equipment, and precision calibration tools necessary to restore your AQ6370B to peak operating condition.

Comprehensive Service Overview for the AQ6370B

Below are the most common failure modes and performance issues we address:

Startup, Firmware, and System Failures

• Freezes on Initialization: We resolve lock-ups during the boot sequence, often caused by failing controllers, corrupted firmware, or internal communication faults.

• No Boot / Cycling Power: Power-related issues such as defective power supplies, aging capacitors, or motherboard faults are thoroughly diagnosed and repaired.

Optical Input, Detection & Spectrum Accuracy Problems

• No Optical Signal Detection: We troubleshoot and repair optical-front-end circuits, detection modules, and alignment issues that prevent proper signal recognition.

• Incorrect or Drifting Measurements: Gain stages, detectors, and ADC sections are tested and recalibrated to restore accurate spectral response.

Display, Interface, and Mechanical Problems

• Blank, Dim, or Unstable Display: Whether caused by inverter failures, LCD degradation, or display-driver faults, we perform complete display repair or replacement.

• Damaged Buttons / Rotary Knob / Power Switch: Mechanical failures are restored to like-new condition with OEM-grade components.

Wavelength, Resolution, and Optical Alignment Issues

• Wavelength Calibration Errors: We perform precision internal and external wavelength calibrations to bring the analyzer back into exact specification.

• Resolution & Monochromator Alignment Problems: Optical stages are cleaned, aligned, and tuned to ensure correct resolution bandwidth performance.

• Low Optical Power Readings: We diagnose detector wear, dirty optics, or aging components that impact sensitivity and correct the issue through repair and recalibration.

Calibration & Performance Standards We Restore

Your repaired AQ6370B is validated to meet or exceed factory-level specifications, including:

• Wavelength Range: 600 nm – 1700 nm

• Wavelength Accuracy: Re-aligned and verified using traceable references
