Installation:
1 Unpacking
1.1 Please open the package,take down the four screw at the bottom of the body.The hardness tester will be installed in the clean and dry room without the corrosive gas and the vibration.The table should be strong and there must be one hole whose diameter is more than 50mm.The screw can pass the hole .
1.2 Please check all the accessories according to the packing list.
