6.2 Single Measurement Evenly smear the coupling agent on the area to be measured. Tightly couple the probe to the material surface, and the thickness of the measured area will show on the screen. When the probe is well coupled to the material, the screen will display the coupling symbol .
6.3 Continuous Measurement Evenly smear the coupling agent on the area to be measured and couple the probe to the material surface. Move the probe along the surface. The gauge will display the current measured value, MAX, MIN and AVG in real time.
Calibration steps: 1) Long press to enter the calibration mode. "Please Calibrate" will show on the screen. 2) Refer to Figure 1 and Figure 2 in 6.2 Single Measurement to evenly smear the coupling agent on the surface of the standard thickness block. Press the probe on the coupling agent to make it tightly contact with the block surface.

4) Press to make the thickness measured by the gauge the same as the value measured by the caliper. 5) Press to calculate the workpiece sound velocity. 6) At this point, the correct sound velocity can be obtained, and the correct thickness can be obtained by measuring the same material with the sound velocity.

●Two-point measurement: Use the probe to measure the same point of the measured object twice. The probe parting plane is 90°, and the smaller value is the thickness. ●Multi-point measurement: Multiple measurements are made in a circle with a diameter of about 30mm, and the minimum value is the thickness.
Page 23
8.2 Cautions during Measurement ●Good measurements are made only when stable coupling symbol appears; ●When there is a large amount of coupling agent on the object surface, it will cause mismeasurement. Therefore, at the end of the measurement, the probe should be quickly removed from the surface. ●The probe surface is acrylic resin and should be gently pressed when used.

8.4 Clean the Outer Shell Alcohol and diluent have corrosive effect on the casing, so wipe it gently with a wet cloth. 8.5 Repair When there are problems with the gauge (such as inability to measure, abnormal LCD display, large error and button operation failure or confusion), please do not disassemble or adjust any parts, and contact after-sales.

Appendix B FAQ and Solutions B.1 Influence of Surface Conditions on Measurement Results B.1.1 Surface Coverings Before measurement, remove dust, dirt, rust, paint and other coverings on the object surface. B.1.2 Rough Surfaces Too rough surface can cause error, or even no reading. The material surface should be as smooth as possible.

Select the angle between the probe partition board and the axis according to the curvature of the material. For pipe with large diameter, the probe partition board is perpendicular to the pipe axis. For pipe with small diameter, the probe partition board is perpendicular or parallel to the pipe axis.

Fiber, porous, coarse crystal materials will cause a lot of ultrasonic scattering and energy attenuation, so that the gauge may have abnormal reading or no reading (abnormal reading is usually less than the actual thickness). In this case, the material is not suitable for measurement with this gauge.

directions. To solve this problem, the test block should have an internal structure in the same direction as the measured material, and sound waves should travel in the same direction in the test block as in the material. In certain cases, the reference block can be replaced by the sound velocity table of the known material.

reading error. Coarse grain size and inconsistent densification of tissues at different positions in the workpiece will cause differences in sound velocity and make the measurement results inaccurate. Note: ● When measuring the casting with rough surface, a coupling agent with high viscosity must be used. ●...

B.6.6 Influence of Oxide Layer on Metal Surface Some metals, such as aluminum, have a dense oxide layer on their surfaces. This oxide layer is closely bonded with the matrix, but the spread speeds of ultrasonic wave in these two substances are different, so it will cause error.
Page 32
B.7 Methods for Reducing Errors B.7.1 Ultra-Thin Materials With any ultrasonic thickness gauge, errors will occur when the measured material thickness falls below the lower limit of the probe. When measuring ultra-thin materials, a false result called "double refraction" sometimes occurs: the reading is twice as thick as it actually is.
