The test situation is the same as the default situation but the ranges are set to the
range necessary for the measurement instead of auto range.

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.
