SMARTSENSOR Ultrasonic Thickness Gauge This unit is an intelligent handheld product, which adopts ultrasonic measuring principle, and is controlled by micro processor, provides quick and precise measurement of thickness for most of industrial material. This unit is widely used in variousprecise measurement for different hardware / parts in industrial realm;one of its important application is to monitor the level of thickness-decreasing during operation of various and pressure container.Diffuselyapplied in manufacture fields, metal processing, and commercial inspection.Scope of application:This unit is suitable for measuring materials that are good ultrasonic conductor such as metal, plastic, ceramic, glass etc.,as long as the measured part in two parallel surfaces for measurement of thickness. This unit is not suitable for cast irondue to its big crystalloid composition.Features:1. Auto calibration to assure the accuracy.2. Auto linear compensation: this advanced software program enhances the precision by correcting the non-linear accuracy of transducer.3. Use and keys to make a quick adjustment for the sound velocity /thickness,and a quick recall to the stored data.4. Coupling status indication: Observing the coupling icon to learn if the coupling is accomplished or not.5. 10 thickness measurement storage and recall function is available6. which facilitates the height work or working in wild area.7. Sound velocity measurement: With a given thickness by a sample hardware to measure the sound velocity, which avoid the further conversion or consultation of the table.8. 12 sound velocity for different material9. Low battery indication10. Auto power off mode designed to conserve battery power.11. More than 10000 times long lift keys.12. Manual power offSpecification: Display: 4-digital LCD display Minimum display unit: 0.1 mm Measuring range: 1.2 to 225.0mm (steel) Working frequency: 5MHz Accuracy: (1%H+0.1)mm,H denotes the measured thickness. Minimum limit for tube measuring: 20*3mm (steel) Sound velocity range: 1000 to 9999 m/s Measuring sound velocity with a given thickness: measuring range: 1000 to 9999 m/s. When the given thickness > 20mm, the accuracy is +/-5%; when the given thickness < 20mm, the accuracy is +/-1mm/H*100%.

Before measurement (1)Connect the transducer with the main unit, press ON/OFF to turn on,LCD display full screen for 0.5 second with backlight,then vertical bar is displayed twice circularly, meanwhile the main display area show 0000 to 9999 progressively.After that, LCD display the last appliedsound velocity with registered memory unit, indicating the gauge is ready for use. (2)Sound velocity selected & adjustment Press"VEL"to enter sound velocity interface, press"VEL"again, you can select reserved velocity data by pressing "" or"" with the word "VEL"blinking on LCD ; If you need to adjust sound velocity data, press "VEL" once more, the "VEL" and "m/s' will keep blinking, indentifying the unit is on adjusting status. Then, increase or decrease the sound velocity to the data you want by pressing"" and "",and this data will beautomatically stored into current sound velocity memory unit. After that, press"VEL" to confirm new sound velocity, and the icons of "VEL"and "m/s"stop blinking. 2. Calibration A calibration should be made for every replacement of transducer or batteries, this operation is sufficiently important to assure the measuring precision. If necessary,this step should be repeated. Pressing"CAL" for
