This procedure calibrates the belt to the system and establishes a test
duration for all the simulated calibrations. A test duration can be
acquired or entered manually. Acquiring a test duration is described
below. Manual entry of the test duration is described on page 2-32.
There are two methods to acquire the test duration—the Full and Partial
methods. The Partial (belt-length measurement) method allows you to
acquire the test duration without measuring the entire length of the belt.
This method, however, should
only be used when the belt length exceeds
1,000 feet. In addition, using the Partial method may be less accurate
than using the Full method. Zero and span calibrations are the most
accurate when using complete passes of the belt.
