砌墙砖收缩膨胀仪注意事项：

★使用时，忌用手直接与标准棒接触，应持外外套部分，以防止标准棒受人体手温的影响。

★仪器用完毕后，应将测量框架的测量头和百分表探拭净，并涂以钟表油；测试过程中，应使百分表的测头缓慢而平稳地与试件接触，不允许冲击和碰撞，严禁将百分表测杆顶过A大量程范围，以免影响表的灵敏度和使用寿命。

Note for wall brick shrinkage and expansion meter:

★ When in use, do not touch the standard rod directly with your hand, and you should hold the outer jacket to prevent the standard rod from being affected by human hand temperature.

★ After the instrument is used, the measuring head and dial indicator of the measuring frame should be cleaned and coated with clock oil; during the test, the dial indicator should be brought into contact with the test piece slowly and smoothly. For impact and collision, it is strictly forbidden to push the dial gauge rod over a large range of A to avoid affecting the sensitivity and service life of the meter.

 

砌墙砖收缩膨胀仪试验方法：

★先将标准棒置于工作台上，拧动调整螺丝使之近似垂直。

★将测量框架置于标准棒的顶头，调整螺杆和螺母，使百分表对准零位（或记下百分表之刻度）。

★将制作养护好的试件两端擦拭净，然后放置在工作台上，然后把测量框架套在试件上，并左右移动表框，使试件与测量框架的测量头准确地接触，此时即可开始读数，并记录下表盘上的刻度值。

★如果实验不是连续进行或实验历时较

Test method for contraction and expansion of wall bricks:

★ Put the standard rod on the workbench first, and turn the adjustment screw to make it almost vertical.

★ Place the measuring frame on the top of the standard rod, adjust the screw and nut to make the dial indicator align with the zero position (or write down the dial indicator scale).

★ Wipe the two ends of the prepared and cured test piece, then place it on the workbench, then put the measuring frame on the test piece, and move the table frame left and right, so that the test piece and the measuring head of the measuring frame accurately contact. You can start reading and record the scale value on the dial.

★ If the experiment is not continuous or the experiment lasts longer
