三、安装步骤：

★必须可靠接地，用膨胀螺栓固定在基座上。

★基座由混凝土浇筑而成(或砖混基础)，底面尺寸约为400mm×400mm，高约690mm。在基座和仪器机架之间宜填垫圈，可通过调整垫圈高度调节桌面水平。

★仪器安装后，其桌面沿彼此成直角的两个直径方向测量时均应成水平。跳桌安装好后，采用流动度标准样(JBW01-1-1)进行检定，测得的流动度值如与给定的标样流动度值相差在规定范围内, 则该跳桌的安装及使用性能合格。

Third, the installation steps of cement mortar fluidity tester:

★ It must be reliably grounded and fixed on the base with expansion bolts.

★ The base is cast by concrete (or brick-concrete foundation), the bottom surface size is about 400mm × 400mm, and the height is about 690mm. A gasket should be filled between the base and the instrument rack. The height of the table can be adjusted by adjusting the height of the gasket.

★ After the instrument is installed, its table should be level when measured along two diameter directions that are at right angles to each other. After the jumping table is installed, the fluidity standard sample (JBW01-1-1) is used for verification. If the measured fluidity value is within the specified range from the given standard sample fluidity value, the installation and Qualified performance.

四、使用方法：

★试样的制作与填装方法按GB2419-2005和GB17671-1999的有关规定，也可参照本说明书附录。

★ 使用前，请用检规检查落距。

★ 将插头接入计数器后对应孔内，将计数器接通电源。

★如跳桌在24小时内未被使用，先空跳一个周期25次。

Fourth, the use of cement mortar fluidity tester:

★ The method of making and filling the samples is in accordance with the relevant regulations of GB2419-2005 and GB17671-1999, and can also refer to the appendix of this manual.

★ Before use, please check the landing distance with inspection rules.

★ Connect the plug into the corresponding hole of the counter, and then turn on the counter.

★ If the table is not used within 24 hours, first skip a cycle 25 times.

五、维护与保养：

使用完毕后，应擦净仪器，清除仪器周围残留胶砂，用轻油稍稍润滑推杆、桌面和凸轮表面。长期不用，仪器应防尘保护，控制器放置在包装盒内。

如仪器不计数，请检查接近开关是否松动、与凸轮间隙是否为1mm~2mm，如有偏离或松动，请调整间隙后紧固

Fifth, maintenance and maintenance of cement mortar fluidity tester:

After use, the instrument should be cleaned to remove the residual rubber sand around the instrument, and lightly lubricate the surface of the push rod, table and cam. If not used for a long time, the instrument should be protected from dust and the controller should be placed in the box.

If the instrument does not count, please check whether the proximity switch is loose and whether the clearance between it and the cam is 1mm ~ 2mm. If it is deviated or loosened, please adjust the clearance and tighten
