The test situation is the same as the fixed range situation, but the integration time
selected for each measurement is correct for the required resolution and accuracy
instead of the default of 10PLC.
Correct delay time: (Subprogram Delay) time = 1.48 s.

The test situation is the same as the situation with correct integration time, but
now the delay time is set to a value that will produce measurements to the desired
accuracy of each measurement instead of the default delays.
