  "definition": "1. A DP system used to measure lithology based on the penetration resistance of the soil. Sensors are mounted in the tip (cone) of the DP rods to measure tip resistance and side-wall friction. Electrical signals are carried to digital processing equipment at the ground surface, where plots of soil type versus depth are recorded. It defines the type of soil based on calibration curves, not site-specific conditions. Therefore, CPT data requires on-site calibration/correlation with actual soil cores.\n\n2. A direct push system used to measure lithology based on soil penetration resistance. Sensors in the tip of the cone of the DP rod measure tip resistance and side-wall friction, transmitting electrical signals to digital processing equipment on the ground surface.",
