DC-3000C SERIES ULTRASONIC THICKNESS GAUGE 7. Preparation before measurement 【7.1】Preparation of the instrument For the newly purchased instrument, please check the instrument and its accessory according to the “3 standard delivery”. If you find it is not the same as the table listed, please contact the manufacture in time. If the instrument is damaged, please do not use it and contact the manufacture as soon as possible. -
Page 8: Treatment Of The Measured Surface
DC-3000C SERIES ULTRASONIC THICKNESS GAUGE Used in the measurement of thin wall thickness and small D7004 curvature surface. Used in the measurement of coarse particles such as cast D2012 iron. 【7.3】Treatment of the measured surface When the surface to be measured is too rough or rusty heavily, please perform the treatment according to the following methods: 1．Clean the measured surface by grinding, polishing or filing, etc. -

DC-3000C SERIES ULTRASONIC THICKNESS GAUGE Notice: Please make sure the probe is not coupled to the test piece when the gauge is first turned on and that there is no coolant on the end of the probe. The probe should also be at the room temperature, clean without any noticeable wear. - Page 10 DC-3000C SERIES ULTRASONIC THICKNESS GAUGE Display the current value, satisfied with the normal measuring needs. Minimum Measurement: Among one measurement, display the point. It is suitable for testing the curvature surface or needs to get the minimum value which is widely used in the thickness measurement of pipeline.

DC-3000C SERIES ULTRASONIC THICKNESS GAUGE wall echoes. Therefore, a good usage of the E-E option is for measuring through coatings (Max. 2mm) to measure only the true metal thickness. 【8.5】Setting 8.5.1 Velocity rate Sound velocity played an important role in measurement. Different material is of different sound velocity. - Page 12 DC-3000C SERIES ULTRASONIC THICKNESS GAUGE Press to move the arrow, press to change the new velocity rate, Press to store this new Velocity. Press to select the location where you want to store, Press to confirm. 8.5.1.3 Velocity measurement Because the workpiece is made from various materials and even the same material with different content and processing technology, the sound velocity will be changed and this change will cause the measuring error.
- Page 13 DC-3000C SERIES ULTRASONIC THICKNESS GAUGE Press to confirm. 8.5.1.4 Velocity storage This function allows user to store 4 new velocities Rate. 8.5.2 Resolution Users can select the displayed resolution. When selecting the high accuracy, the workpiece surface to be measured should be smooth, for the purpose of getting a accurate value.
