用万能表测量并记下表E2-2中输入量和输出量的有效值（伏特数）。

Using the multimeter, measure and record the rms values of the input as well as the output (volts) in table E2-2.

这样，就可以利用抽样来很有效地减少规则所评估的记录的数量，并减少输出量。

Thus, you can use a sampling to effectively reduce the number of records being evaluated by the rule itself by, and reduce the size of the output.
