The document explains how to use the offset function to adjust the measurements of the gauge. The offset function includes wet density offset and moisture offset. The document also provides instructions for testing and measurement.
This document serves as a Quick Reference Card for the Troxler 3440 Surface Moisture-Density Gauge. It provides step-by-step instructions for adjusting offset functions for wet density and moisture, as well as procedures for storing test readings for soil and asphalt surfaces. The guide details the startup sequence, including self-tests and battery checks, and explains how to configure Marshall or Proctor values.
Safety glasses must be worn while smoothing the test surface with the scraper plate.
The location should be at least 2 meters (6 feet) from any building and 10 meters (33 feet) from any other nuclear gauge.
