1、检查系统的电源是否正常、稳定，如果不是的话，就要更换一个正常稳定的电源。 1, check the power supply system is normal and stable, if not, you need to replace a normal and stable power supply. 2、检查机台上各部分的螺丝是否有松脱，如果发现有的话，就要将螺丝上紧。 2, check the machine on all parts of the screws are loose, and if found, tighten the screws. 3、检查机台的四个脚座是否均匀的接触了台座，如果没有的话，需要对四个脚座进行调整使其均匀的接触。 3, the four foot inspection machine is uniform contact pedestal, if not, the need for a four foot seat is adjusted to the uniform contact. 4、确定试片的夹持是否确实，如果没有就要将其夹持好。 4, to determine whether the test specimen clamping is true, if not, it is necessary to hold it well. 5、检查力量感应器和编码器的设定是否正确，按照操作说明将其设定完成。 5. Check the settings of the force sensors and encoders and correct them according to the instructions. 6、在试验开始前检查是否按下了力量归零键和变形量归零键，否则就需要重新开始试验。 6. Before the test starts, check whether the force zeroing key and the deflection zero key are used. Otherwise, you will need to start the test again.
