This article is to simply explain the problems you will have in the process of using Rockwell hardness tester. We hope that will help you better use humidity sensor probe, stainless steel heating tube, PT100 sensor, fluid solenoid valve, cast aluminum heater and a heating ring of Rockwell hardness tester.

1. When you handle the hardness tester, you must remove the weight and pressure head, and put the folder shock pads between the indenter and the sample table; in long-distance transport, it should be restored to the original packaging.

2. It is forbidden to switch the test force in the state where the indenter is in contact with the test specimen.

6. The sample table and the surface of standard hardness block should be clean and have no scratches, rub and bumps.

7. The sample table lifting screw should be regularly lubricated. The specific method is: Remove the sample stage and protection ring, loosen the screw jacket to the screw on the injection of a few drops of light lubricants, and then turn the hand wheel, repeated lift screw to make the oil distribution evenly.
