Operating a Crack Detector:

Pre-Operation Checks:

  • Inspect our structural crack detector for any physical damage or defects.
  • Ensure that the power source is adequate, whether it’s batteries or a power supply.
  • Verify that our device is clean and free from debris.

Setup:

  • Place the detector in the vicinity of the area to be inspected.
  • Adjust any settings or parameters as per the GAO Tek’s instructions.

Calibration:

  • Some structural crack detectors may require calibration. Follow the GAO Tek’s guidelines for calibration procedures.

Detection Process:

  • Activate the structural crack detector according to GAO Tek’s provided instructions.
  • Move the detector over the surface being inspected, paying attention to any signals or indications of cracks.
  • Adjust sensitivity settings if applicable.

Documentation:

  • Record the findings, including the location and size of detected cracks. 

 

Maintaining a Crack Detector:

Cleaning:

  • Regularly clean our detector’s sensors and any other components as specified by the manufacturer.
  • Use appropriate cleaning solutions to remove dirt, dust, or other contaminants.

Battery Maintenance:

  • If the structural crack detector uses batteries, check and replace them as needed.
  • Rechargeable batteries should be charged according to GAO Tek’s recommendations.

Inspection:

  • Periodically inspect the device for signs of wear or damage.
  • Ensure that buttons, switches, and indicators are functioning correctly.

Calibration Checks:

  • If the structural crack detector is calibrated, perform routine checks to verify its accuracy.
  • Follow GAO Tek’s guidelines for calibration verification.

Storage:

  • Store the structural crack detector in a cool, dry place when not in use.
  • Use protective cases or covers to prevent physical damage during storage. 

 

Calibrating a Crack Detector:

Frequency:

  • Calibrate the structural crack detector as recommended by GAO Tek.
  • Calibration intervals may vary based on usage and environmental conditions.

Equipment Needed:

  • Reference standards or test specimens with known crack sizes.
  • Calibration tools provided by GAO Tek.

Zero Calibration:

  • Adjust the detector to a crack-free reference standard to establish a baseline.

Sensitivity Calibration:

  • Adjust the sensitivity settings using reference standards with known crack sizes.

Verification:

Confirm that the structural crack detector accurately detects cracks of known sizes.
