The waste compactorcontainer controllermonitor system allows for periodic substantially real-time oil viscosity measurements of the hydraulic fluid to account for changes in such viscosity. Also disclosed is a method for analyzing a sample using a resonator arrangement. The threaded rods are secured by locknuts 24A on one end and the threaded rods are secured by locknuts 24B on both ends. The method includes pre-defining a default order of symbols in the residual data block.
