CONTROL SELECTION     Quick selection of templates used in the system.	BASIC CONTROL     Provides machine control and access to the templates for programming transducer set-up, calibration, etc.	FUNCTION GENERATOR     Provides the operator with the ability to program custom testing sequences in force and  position control.
TRANSDUCER SET-UP     Allows access to all transducer channels for programming changes in gains, voltage to engineering units, offsets, etc.	TRANSDUCER CALIBRATION     A highly effective procedure for rapid calibration of the system's transducers. A polynomial curve-fitting procedure is used to obtain the best curve through collected points.	EXUDATION TEST     Automatically performs the exudation phase of California Test Method 301. At the end of test "Word Pad" appears showing test data formatted for optional spread sheet entry.
STABILOMETER RESISTANCE TEST     Automatically performs the stabilometer phase of California Test Method 301. At the end of test "Word Pad" appears showing test data formatted for optional spread sheet entry.	STABILOMETER VALUE TEST     Automatically performs the exudation phase of California Test Method 366. At the end of test "Word Pad" appears showing test data formatted for optional spread sheet entry.	LIMITS     Automatically turns off the hydraulic actuator to provide protection for expensive fixtures when load (force) or stroke (position) limits are exceeded.
