Abstract
A system and method for calibrating a compactor. The compactor may have a roller. The system may comprise a display and a controller. The controller may be configured to receive, when the roller rotates in a first direction, a first baseline compaction value, receive, when the roller rotates in a second direction, a second baseline compaction value, calculate an offset between the first and second baseline compaction values, receive a subsequent compaction value obtained while the roller is rotating in the second direction, adjust the subsequent compaction value by the offset difference, and display an adjusted subsequent compaction value on the display.
