There are four options provided for background count time.
Background radiation affects readings; a new background count
is necessary when background environment or the material
measured changes.
A one-minute background count is recommended for
measurements depths two inches through eight inches.
For EGauges that offer depths of 9-12 inches, the
background count is required for these depths. A
minimum one- minute BGD count will be required by
default. These deeper measurements are more
sensitive to changes in background radiation.
