求翻译：调节速调开关(pic6)，观察待测样品是否可以开始执行测试，必须确保试验机连接杆上下摆动的角度范围不能大于产品正常使用所能达到的最大范围是什么意思？

Adjust the speed override switch (pic6) to observe whether the sample can begin to perform the test must ensure that the connection rod of the testing machine swing angle range can not be greater than normal use can achieve the maximum extent

Adjust speed adjustment switch (PIC 6) to be tested, and observe whether or not you can begin the sample test, you must make sure that the connecting rod up and down swing angle range cannot be greater than the normal use of the appliance to achieve the maximum range

Adjustment velocity modulation switch (pic6), the observation treats measured whether the sample can start to carry out the test, must guarantee the angle scope which about the testing machine go-between swings not to be able to be bigger than the most wide range which the product normal use can ach

Adjust speed adjusting switch (pic6), see whether the test samples can start test execution, you must ensure that testing machine for connecting rod up and down angle range cannot be greater than the normal use can achieve the maximum range of the product

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.
