(1) Wipe the top surface of the screw and the upper and lower end surfaces of the worktable, and place the worktable on the screw table;
(2) Clean the support surface of the specimen and place it on the workbench, rotate the handwheel to slowly raise the workbench and push up the indenter until the small pointer points to the red dot and the big pointer rotates 3 circles vertically upwards;
(3) Rotate the indicator shell to make the long engraved line between C and B align with the big pointer;
(4) Pull the loading handle, apply the main test force, and the large pointer of the indicator rotates counterclockwise;
(5) When the rotation of the indicator needle stops, the unloading handle can be pushed back to remove the main test force;
(6) Reading from the corresponding scale on the indicator;
(7) Turn the handwheel to lower the test piece, then move the test piece, and carry out a new test according to the above steps (2)-(6);
(8) After the test, cover the machine with a dust cover.
