The system runs closed-loop control in displacement, load, speed and pressure modes, so the controlled variable is held rather than approximated.

PID settings are adjustable across the range of samples, which is the practical difference between testing a stiff overconsolidated clay and a soft normally consolidated one on the same machine.

An auto engage function applies the seating load, removing the part of the setup where operators most often disturb a specimen. The same control loop runs across the 10, 50, 100, 250 and 500 kN load ranges, so the behaviour does not change with frame size.
