outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 点击合适的模块按钮进入校准部分。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 1.长度/强度模块<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 长度/强度模块有3个校准选项:长度/强度校准、光透镜至断裂点校准、变形量校准。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; (1)长度/强度校准:长度/强度校准允许操作者设定标准值,设定校准参数,选择校准选项。标准值是短棉和长棉的参考值,在标准校准棉箱上可以找到。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 在校准项目选项栏中允许操作者根据需要选择任一选项进行校准:长度/强度、长度/强度/短纤维、短纤维。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 首次校准时,可以把校准参数栏中的所有“偏移量”设定为0,之后仪器会自动计算这些值。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 校准后,不用再改变这些值。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 系列校准试验前(12个样品),检查校准棉纤维的标准值与被测试校准棉箱外的值是否一致。如果不一致,重新设定校准棉的值。按以下顺序开始校准试验:<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; ①把短/弱棉样放在取样器里并按开始按钮。<br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp;
