Page 3: Overview
1 Overview The Portable surface roughness tester MR200 could give a fast, accurate test of the roughness, applied on work site and mobile measurement. It is portable to carry, easy to operate, reliable to test and full functional advantages. Adopted 2.7 inch OLED Screen, equipped with wireless communication module, Micro-USB port, standard Bluetooth module and SD card, it can not only achieve wireless remote control and measure but also can connect with PC, wireless Bluetooth printer and memorize more data. -
Page 4: Working Principle
1.3 Working Principle This instrument adopts needle scanning method to test the surface roughness of the work piece. When measuring roughness of part surface, the probe is placed on the surface of the part and then tracing the surface at constant rate. The probe acquires the surface roughness by the sharp stylus in probe. -

3.5.1 Stylus Position First, check the stylus position. When measuring in surface, usually don’t need adjust stylus position. When using the Height Lifting Pillar to measure the work-piece surface, you need to adjust the vertical height of the instrument to determine the pointer near zero. After the pickup is exposed to the measured surface, the measurement can begin. -
