General Information The Proving Ring Penetrometer is a cone type of penetrometer which can be used in a number of applications. It serves as a rapid means for determining the penetration resistance of soils in shallow exploration work. The reading obtained in this method maybe correlated to standard or modified compaction data for compaction control in the field. Trafficability relationships can be obtained for quick field evaluation of sites.
Rezeroing the Instrument When reading has changed at any time or if any part is changed in the penetrometer, the instrument should again be zeroed as described in the Zeroing Instrument section above. Operation Be certain that the dial indicator has been set to zero position. Select the site to be tested and clear the test location so that a flat and clean surface is available for testing. Hold the assembly vertically on the test location.
Precautions Keep the instrument vertical while taking the measurements. Do not attempt readings higher than the capacity of the dial since this will overstress the proving ring. Do not withdraw the instrument by the ring but always by the rod. Care and Adjustment General Care All parts of the penetrometer are plated for resistance to corrosion and should be relatively maintenance free.
