The 3411-B can display the percent compaction achieved at the
test location if a target value for the particular material is
entered into the gauge register. Follow the procedure below to
enter a Dry Density (Proctor) target or a Wet Density (Marshall)
target, which is determined in the laboratory.
1. Press 〈SHIFT〉 and 〈SET〉 and read the stored value. For
asphalt, the Marshall value should be stored in this register.
For soils, the Proctor value should be stored.
2. If the value is too low, place the (+/-) switch on (+). Press
〈SHIFT〉 and 〈SET〉 and THEN release the 〈SHIFT〉 key. The
display value should increase; release the
〈SET〉 key when
the desired value is displayed. If the value is too high, utilize
the same procedure but with the switch on (-).
3. On soils and bases, press 〈SHIFT〉 and 〈%PRO〉 to read the
percent Proctor.
4. On asphalt, press 〈SHIFT〉 and 〈%MAR〉 to read the percent
Marshall.
