How do you use a manual Rookwell hardness tester?
(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.
