The gauge provides three different count times for taking
measurements. To change the count time, see page 3–10.
A two-minute count time is recommended for the
density measurement on most materials.
For the EGauges that offer the 9-12-inch depth
positions, a minimum 3-minute count is required for the
depths below 8 inches.
