Holding the DM-DCP in a vertical position, raise the hammer until it touchs, but does not impact, the handle. From this po- sition let the hammer free-fall so it impacts the anvil/coupler assembly. Care should be exercised when raising the ham- mer to ensure that the hammer is touching the bottom of the handle but not lifting the cone before it is allowed to drop. -

of the handle but not lifting the cone before it is allowed to drop. The hammer must be allowed to fall freely with its downward movement not influenced by any hand move- ment. The operator should also be careful not to exert any downward force on the handle after dropping the hammer. -

Page 16: Maintenance
Maintenance Normal usage of your DM-DCP results in wear of the metal parts that make up the device. In order to ensure maximum service life, periodic inspections of the DM-DCP for fatigue or damage should be done. Any parts found to be fatigued or damaged should be replaced. -

430 to 10,800 psf. They are typically used to asses materials at depths up to 30" (750mm), but can use extensions to extend that range to 6ft. (2m). All Humboldt DM-DCPs comply with ASTM D6951 specifications and come with a chart to compute CBR values. - Page 18 Humboldt’s DM-DCPs are known for their high-quality manufactur- ing and reliability, and, are available with either threaded connections or with a quick-connect design. Both Humboldt DM-DCPs feature our exclusive easy-grip hammer that provides a finger grip machined into the back side of the hammer flange, which provides easy, non-slip lift- ing when performing a test.
