Controls
Model 685.53 Grip Control Module Operation 17
Pressure Adjusts the amount of hydraulic pressure applied to the grips for gripping the
specimen.
This is a multiturn knob. Pressure increases as the knob is turned clockwise
and decreases as the knob is turned counterclockwise.
To determine the correct operating pressure, see “Adjusting the Output
Pressure” on page 19.
Rate Adjusts how fast the grips clamp and unclamp. This control requires the use of
a hex-key wrench for adjustment.
Adjust the Rate control clockwise to slow the clamping of the specimen.
Otherwise, adjust the Rate control counterclockwise to increase the clamping
speed.
To adjust the clamping rate, see “Adjusting the Rate Control” on page 20.
Pressure Gage Shows the current hydraulic pressure setting for grip operation.
The gage includes scales for both MPa and psi units.
Use the gage while adjusting the Pressure control to achieve the desired
clamping pressure. See the grip product information manual for gripping
pressures.
