The testing machine should be installed in a clean, dry, and temperature-uniform room. The possibility of performing long beam bending tests on the machine and using a mirror-type extensometer should be considered; therefore, sufficient clearance should be left around the machine.
No special foundation is required for the installation of the main body of the testing machine and the force gauge. Simply prepare a general foundation according to the foundation plan, leaving holes for anchor bolts and then pouring concrete.
To level the main body of the testing machine, place a level on the outer circumference of the hydraulic cylinder and check the machine base in both longitudinal and transverse directions, as well as horizontally. Use a level with an accuracy of 0.10/1000 mm to find ±1 division. If it is not level, add shims under the base for adjustment.
The force gauge has two holes on top for threading steel wire ropes during reinstallation.
Leveling the force gauge is crucial. When leveling, align the left side of the pendulum rod with the graduation line on the standard line plate and keep it stationary. Then, use a bent ruler against the large surface of the upper part of the pendulum rod, and use a 0.1/1000 mm level on the bent ruler to find ±2 divisions. If incorrect, add shims under the base, and ensure the pointer is aligned to zero whether the pendulum is attached or not.
Open the iron door at the top rear of the dynamometer to check if the plumb bob's string is wound in the groove of the pinion gear coaxial with the pointer. The string length should be appropriate, neither too long nor too short. The maximum length should not touch the horizontal partition, and the minimum length should be such that the plumb bob does not touch the pinion gear after one full rotation.
