Getting Things Ready
If you plan to perform any of the procedures described later in this
chapter, be sure that you get the hydraulic fluid up to temperature.
Be sure that both the hydraulic fluid and the servovalve are at
operating temperature. Remove any specimen and run the system in
displacement control for at least 30 minutes using an 80% full-scale
length command at about 0.1 Hz.
Refer to “How to Warm Up Station Hydraulics” in Chapter 2, Common
Tasks of the FlexTest SE User’s manual for a detailed procedure.
