求翻译：如果实验期间观察待测样品的测试情况，可关闭速调开关，观察结束后打开速调开关继续测试直至测试结束，自动停止，完成测试。是什么意思？

If the experiment during the observation of the sample test, you can turn off the speed adjust switch and observe the end to open the speed override switch to continue to test until the end of the test, auto stop, finished testing.

If the lab test samples to be observed during the test, you can turn off the switch as soon as possible after the end, the open switch as soon as possible to continue testing until the end of the test, the automatic stop, complete the test.

If the experimental period observation treats measured the sample the test situation, may close the velocity modulation switch, after the observation had ended until turns on the velocity modulation switch to continue to test tests finished, the automatic stop, completes the test.

If the experimental observation of the sample to be measured during the test, speed adjustable switch is turned off, after the end of observation opened speed adjustable switch to continue testing until the end of the test is automatically stopped, to complete the test.

Installs the test specimen: Fixes according to the test spot the product in the multi-purpose adjustment platform on (pic5), simultaneously will treat using the manipulator measured the sample and the testing machine go-between will connect in together.
