The 3458A is placed in remote operation by the computer and is reset to its default
conditions. The integration time is set to 10 PLC, the settling delays are set so that
first reading after a function or a range change meets its specified accuracy. Auto
range is on. The computer asks the dmm to change range, or function, or
integration time for 10 of the 37 measurements. The others are measured in blocks
in the same measurement configuration.
Fixed Range: (Subprogram Fixed) time = 15.98 s.

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.
Correct integration time: (Subprogram Integrate) time= 3.76 s.
