Operating a Flaw Detector:

Intuitive User Interface:

  • Familiarize yourself with GAO Tek’s flaw detector’s user-friendly interface for easy navigation.
  • Use the intuitive controls to adjust settings such as frequency, gain, and screen display.

Optimal Probe Selection:

  • Choose the appropriate probe for the specific flaw detection application.
  • Ensure proper connection and alignment of the probe with the GAO Tek flaw detector.

Adjustable Parameters for Precision:

  • Utilize adjustable parameters such as gain and frequency to fine-tune flaw detection based on material and inspection requirements.
  • Monitor real-time signals on the display for immediate feedback during inspections.

Data Recording and Analysis:

  • Explore GAO Tek’s data recording capabilities to document inspection results.
  • Leverage analysis features to interpret flaw patterns and make informed decisions.

 

Maintaining a Flaw Detector:

Regular Inspection of Equipment:

  • Conduct routine visual inspections of the flaw detector for physical damage or wear.
  • Check cables, connectors, and probes for any signs of wear and tear.

Battery Care and Charging:

  • Follow GAO Tek’s guidelines for battery maintenance and charging.
  • Ensure the flaw detector has a fully charged battery before starting inspections.

Calibration Verification:

  • Regularly verify the calibration of the flaw detector using reference standards.
  • Follow GAO Tek’s calibration procedures to maintain accurate flaw detection capabilities.

 

Calibrating a Flaw Detector:

Calibration Reference Standards:

  • Use GAO Tek’s recommended calibration reference standards for accurate calibration.
  • Follow the step-by-step calibration procedure outlined in the user manual.

Zero Offset and Sensitivity Calibration:

  • Perform zero offset and sensitivity calibration to establish a baseline for flaw detection.
  • Adjust settings to achieve optimal sensitivity while minimizing false indications.

Verification with Test Blocks:

  • Utilize test blocks with known flaws to verify the flaw detector’s accuracy.
  • Confirm that the flaw detector accurately detects and displays flaws in the test block.

Periodic Calibration Checks:

  • Conduct periodic calibration checks according to GAO Tek’s recommended schedule.
  • Keep calibration records to track the flaw detector’s performance over time.
