Page 3: Installation And Adjustment
Brinell, Vickers hardness tests under the cooperation of self -furnished surveying microscope. The model ISH-BRV Brinell, Rockwell & Vickers hardness tester adopts rotating type load changing mechanism as well as optical measurement indicating system, and the microscopic survey installation is mounted on the body of the apparatus. - Page 4 Adjustment of the loading speed: Tester unpacking: Oil contained in the buffer has already been fully drawn out before Open the packing box cover and take out all cushion packaging and leaving the factory, hence, before use, oiling the materials. Remove the accessory box. necessary.
