QA SAMPLING (SPECIAL KEY)
The QA Sampling function generates random sample locations.
Using random sample locations helps ensure fair and representative
quality assurance sampling. The gauge bases the QA sample
locations on the operator input for
average sample separation and
total number of samples. The average sample separation is the
average distance between QA samples.
For example, if the QA protocol requires a sample every 500 feet on
a 2000-foot strip, the samples will be randomly separated and the
number of samples will be four. The first location will be a
randomly selected value between 1 and 500; the second between
501 and 1000; the third between 1001 and 1500; and the fourth
between 1501 and 2000.
After the gauge generates the sample locations, the operator can
view or print the locations as a guide for QA testing.
