USER DEFINED
A user defined test could be used for any other test beside Marshall and
CBR / LBR. The test would require up to 3 channels associated with it.
User Defined test such as Triaxial (CU) would require 3 channels (load,
displacement, pore water pressure), A Triaxial (UU) requires 2 channels
(load and displacement), Unconfined Compressive strength would require
2 channels (load and displacement), Soil-Cement and TSR would requires a
single channel (load).
