It is used to check and check Jack force values. Equipped with other components, it can also be used for forming high strength and high strength specimens, and testing high strength compressive strength of specimens.

Should be taken before use to check whether there is phenomenon of loose coupling nut counterforce frame, will be jack into the reaction force measurement test center, good connection between the pump and tubing, will force value sensor into the jack and counterforce frame clamp test area, connection between the good and strength display data cables, preheating 5 minutes after turning on the power supply, start the pump, according to GJJ - 621-2005 (hydraulic jack verification regulations) in order to load and read a strength display data.

Reverse frame test space: 850mm

Maximum test force of force measuring system: 500KN

The accuracy of the force value: 0.01KN

The accuracy of the indication: + 1%FS (linear + lag + repeatability)

Temperature range: 30 ~ 70 /85 DEG C

Output sensitivity: 2 + 0.5 MV
