NOTE
On soils that have not previously been checked by a
nuclear gauge, a moisture sample may be obtained
at a point of test to determine if a correction factor is
needed. If a correction factor is necessary, it can be
determined by following the procedures starting on
page 5-2. A correction factor for a given soil need
only be determined once. The correction can then be
reused in future testing with the same gauge.
