Mattel MT150 / 160 Ultrasonic Thickness Gauge Features a warning sound when set to [open], in each key, the measurement is completed, the measured value exceeds the measurement limit, the case will delete data buzzer sounding cry. Change the alert sound settings can be achieved through the following actions: In the thickness measurement mode, the buttons to change the current setting, the screen displays the current settings for the warning sound, [start] appears as: BEEP OFF, [Off] appears as: BEEP ON. LCD backlight instrument with EL backlight function to read in dimly lit office measurements. Since the backlight is turned on after the instrument power consumption increased significantly, so please turn on the backlight when it is necessary, in order to save electricity, extending battery life. Button can turn on or off the backlight. Battery level indicator instrument host built with 2 AA-size connected in series (5) alkaline batteries. When the battery is fully charged, the power indicator displays the full grid; battery used for some time, the battery symbol will appear non-full frame; when the battery is nearly exhausted, the battery symbol will flash show what ultrasound can do, and you should immediately Replacement battery. Ultrasonic thickness measurement common problems and treatment methods in the use of ultrasonic thickness measuring the workpiece thickness, ultrasonic thickness of principle, may be due to human causes or other causes assay results to a certain bias, the same, the use of Mattel MT150 / 160 if you do not pay attention when measuring the workpiece or operator error, ultrasound, may also cause the measurement results to error, ultrasonic thickness gauge price, especially some of the considerations to make a brief introduction. Not parallel to the surface in order to get a stable and reliable thickness measurements, other surface material being tested must be parallel or coaxial with the measured surface, otherwise it will lead to greater measurement error or no readout. Effect of temperature on the measurement results of the thickness of the material and the ultrasonic propagation velocity in the materials are affected by temperature. When high measurement accuracy requirements, can be test block comparison method, which uses the same material, the approximate thickness of the test piece was measured under the same conditions of temperature and temperature compensation coefficient obtained by this factor correction measurements of the workpiece Attenuation material effect on the results of some such as fibers, porous, coarse grain and other materials, they will cause a lot of ultrasonic scattering and attenuation that may appear unusual instrument readings or no readings (typically less than the actual thickness of the anomalous readings) . In this case, the thickness of this material is not suitable for thickness measurements. Ultrasound, ultrasonic principle, ultrasound can do what the United States by Beijing Technology Co., Ltd. Tyco. Ultrasound, ultrasonic principle, ultrasound can do what is Beijing Mei Technology Co., Ltd. Tyco (www.mitech-ndt.com) this year introduced a new upgrade, the above picture is for reference only, please call the contact picture on this page or telephone obtain the latest information, contact: Nan party.
