3. PROCEDURES
3.1 Equipment Check
3.1.1 Before beginning a test, check to ensure the
Drive Rod is straight by rolling the rod on a flat surface.
Note: The Drive Rod may bend if driven beyond refusal
(see para 3.3.3).
3.1.2 The Hardened Point must be checked to ensure
the 3 mm flat is discernible. The flat area will become
rounded after about 250 tests and the tip should be
replaced. Rarely, if ever, does the Hardened Point wear to
the extent that the diameter fails to meet specifications
(see para 2.2).
3.1.3 The Adapter o-ring should be should be clean and
free of cuts or nicks. Each pack of 25 Disposable Cones con-
tains a replacement o-ring.
3.2 Assembling
3.2.1 Vertical Scale- Secure the black delrin Upper
Attachment by tightening the screw just below the end
cap. Next, place the foot over the end of the Drive Rod.
Slide the Vertical Scale through the square hole in Upper
Attachment and into the foot.
3.2.2 Tip- Tighten the tip securely with the wrenches.
3.2.2.1 The reusable Hardened Point is used in soft, non-
cohesive material, i.e. where the DCP advances more than
1/2” per blow (CBR <18%).
3.2.2.2 The Adapter and Disposable Cones should be
used for cohesive material and material where the DCP
advances less than 1/2” per blow (CBR >18%). Attach the
disposable cone to the adapter by applying pressure and
rotating the cone. This will ensure proper seating and
extend the life of the o-ring.
3.2.3 Drive Rod (30”, 37 3/4”, or 48”)- Slide the Drive
Rod into the anvil, insert the Quick-Connect Pin and
retainer clip. Treat the drive rod with a light film of oil
to minimize skin friction. This is especially important in
cohesive soils.
