MEASURING THICKNESS 3.1 Sound Velocity Calibration In order for the gauge to make accurate measurements, it must be set to the correct sound velocity for the material being measured. Different types of material have different inherent sound velocities. If the gauge is not set to the correct sound velocity, all of the measurements the gauge makes will be erroneous by some fixed percentage. The One‐Point calibration is the simplest and most commonly used calibration procedure optimizing linearity over large ranges. The Two‐point calibration allows for greater accuracy over small ranges by calculating the probe zero and velocity.

- Page 9 3.4 DISPLAY MODES There are three measuring interface display modes: normal mode, A‐scan mode and B‐scan mode. And there are three display modes of Normal interface: The thickness value mode, Difference/rate of reduction measurement mode, MAX/MIN measurement mode. Select this in “VIEW MODE” of configuration. ATTENTION: When the probe is properly “coupled” to the surface of the object being tested, the value on the display will be shown in WHITE. If not coupled properly then the values will be shown in GREEN. When the values exceed the upper or lower limit setting then the values will be shown in RED. THICKNESS VALUE MODE: This interface shows the velocity of material, the present thickness value and unit. 3.4 NORMAL MODE INTERFACE 1—the present thickness value 2—unit 3—material velocity 4—battery power 5—A‐scan interface DIFFERENCE/RATE‐OF‐REDUCTION MODE: This interface shows the measured value, the preset nominal thickness value, the difference between the measured value and the preset value and the ratio between the difference and the normal value.

Press the RESET button to get the limits when measuring the thickness. - Page 11 A‐scan mode: This interface allows you to see the present thickness value and the A‐scan waveform at the same time. The right side of the interface is the specification adjusting area, which can be adjusted for a more precise result.

BLANK—hide the unnecessary and useless clutter in front of the main waves. The red line on the bottom of the screen shows the blank confines. The adjusting blank confines are the present range confines. Incorrect readings can be caused by material issues such as corrosion, internal material defects or even a specific material such as aluminum. Only adjustments in the Gain can solve part of the problem. - Page 13 2. There are some defects in the testing object, and the gate locks the defect echoes. As shown in the following figure, the thickness of the testing object is about 10mm, but as there are obvious defects (the defect echoes are shown on the display) and the gate locks the defect echoes which have broken the gate, thus, the testing result shown is the thickness of the defect area. The right measurement can be realized by adjusting the gate setting above the defect echoes. 3.9 REAL CASE 2 3. If there are some surface faults in the testing object and the gate locks the defect echoes, the measuring result will be the thickness of the defect area. In this condition, the customer can use the BLANK function to get the correct testing result. As shown in the following figure, the line on the bottom of the screen, which we use to shield the defect echoes, indicates the blank confines and makes...

By moving the probe across the surface of the workpiece you can obtain a cross sectional profile of your part. This allows for viewing the contour of your part.
- Page 15 3.8 DUAL‐ECHO (THRU‐COATING) MODE The UTG‐4000 can accurately measure the actual material below the coating utilizing the dual echo measurement principle. This feature allows you to measure the material without having to destroy or remove the protective coating of a surface. Press “M” to go into the parameter interface and set Measurement mode to DUAL‐ECHO and press “M” to return to the main measurement screen. 3.8.1 A‐Scan interface in dual‐echo mode The UTG‐4000 allows you to use A‐scan while in the dual‐echo mode. This feature has added E‐blanking option as well as the option to cancel GATE. When measuring, the blue strip area indicates the length of echo blanking./ the waveform above this is considered invalid. See fig 3.16 below: 1) Identification of dual‐echo mode 2) Blue arrow indicates secondary echo 3) E‐blanking 4) Blue line: the length of echo‐blanking 5) Red line: length of initial blanking 6) Red arrow: indicates first echo Blanking in Dual‐Echo Mode: a) Initial blanking: The red blanking line starts at zero. The waveform within the scope of the red strip is considered invalid due to lack of clutter between the starting point and the first echo.

5. CARE AND MAINTENANCE 5.1 POWER SOURCE INSPECTION During the usage of the gage, the current battery power will be shown on the display. When the battery capacity is low, the customer should change the batteries promptly so that the measuring accuracy won’t be influenced. The steps of changing batteries are as follow: 1. Turn off the gage. 2. Loosen the screws on the back of the unit and remove the battery cover. 3. - Page 18 Applications Notes: Measuring pipe and tubing. When measuring a piece of pipe to determine the thickness of the pipe wall, orientation of the transducers is important. If the diameter of the pipe is larger than approximately 4 inches, measurements should be made with the transducer oriented so that the gap in the wearface is perpendicular (at right angle) to the long axis of the pipe. For smaller pipe diameters, two measurements should be performed, one with the wearface gap perpendicular, another with the gap parallel to the long axis of the pipe. The smaller of the two displayed values should then be taken as the...
- Page 19 An additional important consideration when measuring laminates, is that any included air gaps or pockets will cause an early reflection of the ultrasound beam. This effect will be noticed as a sudden decrease in thickness in an otherwise regular surface. While this may impede accurate measurement of total material thickness, it does provide the user with positive indication of air gaps in the laminate. Suitability of materials Ultrasonic thickness measurements rely on passing a sound wave through the material being measured. Not all materials are good at transmitting sound. Ultrasonic thickness measurement is practical in a wide variety of materials including metals, plastics, and glass. Materials that are difficult include some cast materials, concrete, wood, fiberglass, and some rubber.
