Overview of the ultrasonic thickness gauge, its principle, and applications.
Explanation of the function of each key on the control panel.
Description of all icons and readings shown on the device's LCD screen.
Step-by-step guide on how to perform a thickness measurement.
Procedure for adjusting the sound speed setting within the unit.
Instructions for calibrating the device using a standard calibrating piece.
Method to determine the sound speed of a material using a given depth.
Steps to reset the sound speed to its factory default setting.
Remove dust, dirt, rust, and grease from the workpiece before measuring.
Smooth the surface by milling or polishing to avoid measurement errors.
Adjust transducer angle for regular textures to improve accuracy.
Orient transducer correctly for accurate wall thickness measurement of pipes.
Take the smaller of two readings for complex shape material measurements.
Ensure parallel surfaces for accurate ultrasonic response.
Temperature affects material sound velocity; measure at consistent temperatures.
Fiber or porous materials may cause attenuation, leading to inaccurate readings.
Use sample blocks for calibration to ensure accuracy and minimize velocity variation.
Transducer wear can cause inaccurate readings; replace if necessary.
Guidance on selecting the appropriate transducer based on material and application.
Measure thin materials using sample block method to determine minimum limit.
Clean stained or rusting surfaces to prevent inaccurate readings.
Use correct velocity for material measurement to avoid fault readings.
Polish transducer surface to maintain sensitivity and accuracy.
Use ZERO function for calibration with standard blocks or other materials.
Ultrasonic wave cannot measure thickness of uncoupled multilayer/composite materials.
Calibrate with sample blocks for oxidized surfaces to account for error.
Distinguish abnormal readings caused by rust, erosion, or incorrect calibration.
Select and use proper coupling agent for effective ultrasonic wave transmission.
Guidelines for battery replacement, transducer protection, and cleaning the unit.
