The HI-2200 System is a lightweight, easy to hold instrument for less accessible measurement locations such as towers and ladder access situations.

它小巧轻便，可手持，并不易受测量场所的影响， 例如在塔顶等位置。

But its effectiveness is based on accuracy of modal testing, while the measurement locations and the number of transducers have a decisive effect on testing results.

但其有效性的基础是建立在模态测试的准确性上，而传感器布设的位置、数量对测试结果起决定作用。

Now from the mode shapes shown we can see that there are sufficient number of points to describe the mode shape for each mode. But there are a total of 45 measurement locations on this plate.

从图示的模态振型中，我们现在可以看出，有足够数量的点来描述每一阶模态的振型。
