Page 5: Installation And Adjustment
4 Installation and adjustment Remove top cover of wood crate, then remove the three M10 screws from the underside of the base. Lift the machine very carefully from the bottom. Do not lift from the head, the side doors or other points any time. Remove all accessories and the weights that are attached to the baseboard by the straps. - Page 6 Remove the screw on top of the machine that holds the canopy; Slightly lift the canopy from front; remove the canopy after removing connecting cables out; remove all elastic packaging belts from lever. Method of extracting and plugging cable is as figure 4.2. For extracting cable, part the barbs by exerting force on both sides, then the plug of cable will eject out.

Page 8: Operating Methods
5 Operating methods 5.1 Testing preparation Connect power supply and turn machine on. The 900-385 will perform a self check and relative information such as type, serial number of the tester, software version will be displayed on screen. Tester will come to main menu after self-checking; current (last used) test parameters will be displayed on screen. -

Figure 5.2.1 Figure 5.2.2 The selection of test force is automatically adjusted once you select your hardness scale. There are three test forces of 60kgf(588.4N), 100kgf(980.7N) and 150kgf(1471N) for Rockwell hardness measurement, and also three test forces of 15kgf(147.1N), 30kgf(294.2N) and 45kgf(441.3N) for Rockwell superficial hardness measurement. -
