Hi
Direct relationship for cms would be - thinking along these lines , Cms = compliance of the suspension = how much the cone moves per unit of force
we need to measure the air pressure to move the test cone - 1mm, 2mm, 3mm, 4mm, 5mm to xmax.
the cms will be = movement / P x A, and we can do a few calculations and get the average cms the movement.

this will need some controllers controlling the directional valves - if you use solenoids , this will help maintain velocity of the cone. if we can get / solve constant velocity by mechanical means , ie pneumatics here - we will be able to work out the calculations for bl & cms.
And get an idea of the restoring force of the suspension system beyond xmax. -
I have had a little more time to test it and my opinion about the DATS LA has been hardened: The device cannot be used without an additional triangulation laser. The displacement values output by DATS LA are at best close to the measured values. But how do you know that without a laser?
There are also other issues:

There are also other issues:
- Miserably long storage time
- DATS LA calculates incorrectly with the "Specified Mmd method
- Cms is output with the wrong unit
- Within the "Symmetry Data Export" columns are mixed (Cms - Kms)
- It would be nice to have a Csv export for easier post-processing of the data
