ONTROL DESCRIPTION

Hydraulic Grip Controls

Controls the optional hydraulic grips. Hydraulic grips let you quickly and

easily install and remove specimens. The left handle controls the lower grip

and the right handle controls the upper grip.

Pressure

Adjusts the amount of hydraulic pressure to the grips. The adjustment range is

1–21 MPa (100–3000 psi) or 1–69 MPa (100–10,000 psi). The highest

pressure setting depends on the maximum pressure setting. Adjust the control

clockwise to increase the hydraulic pressure. Use the pressure gage to measure

the clamping force.
