2.安装：

1) 从包装箱中取出机箱底座与支柱。

2) 将三只水平调整脚旋入底座螺丝孔中（图一）

3) 主机安装：

a. 旋松机箱中螺钉取出主机。

b. 旋松手柄固定钮，将电源线嵌入手柄夹头槽内

c. 将手柄穿入夹头槽底圆孔中

d. 旋紧手柄固定钮夹紧手柄，并使主机基本保持水平

e. 拆除指针主杆上的橡皮圈和主机下端的黄色包装套圈。

警告！在未拆除上述两项前不可通电开机，否则将损坏机器。

f. 接上电源，调整水平调整脚，使水准器中水平泡居于中心圆圈中。Installation:

1) Take out the support stand, column from the packing box.

2) Screw the column into the hole at the rear of the support stand with the teethed side facing the front of the support stand. Tighten the 3 adjustments underneath the stand support.

3) Installation of Main Body:

a. Take out of the main body and loose the screw.

b. Loose the fixed button and embed the power cord into the groove of the clamp.

c. Let the handle get through the hole of groove of the clamp.

d. Tighten the fixing screw on lever and keep the main body horizontal.

e. Remove the rubber band on the indicator control lever, release the yellow screw at the lower end of the instrument and lastly remove the yellow packing ring.

Warning！

Do not power on before the 2 operations above, otherwise damage will be caused.

f. Power on, make adjustment of the support stand and make sure the leveling bubble is in the center.

3. 操作：

1) 首先将保护架右旋上仪器下端。

2) 准备被测液体，选择直径>or=70mm 的圆柱型容器。

3) 按测量要求的精度，准确控制被测液体的温度

4) 估计被测液体黏度值的大致范围参考量程表选好转子号，并将转子左旋入连接螺杆(图4).然后旋转升降钮（图5），使仪器慢慢地下降，逐渐浸入测量液体中，直至转子液面标志和液面平为止。（图4）按下指针锁定杆，开启电源开关，放开指针锁定杆，使转子在液体中旋转，一般20~30秒的运转，待指针趋于稳定。按下指针锁定杆，使读数固定下来，再关闭电机，使指针停在读数窗范围内，直接读出数据。当电机关停后，如指针不处于读书窗内，应继续按住指针锁定杆，反复开启和关闭电机，使指针处于读数窗内。如选用6和12转/分时，可直接读取读数，不需锁定指针。

5) 读数指针一般在30~90分度之间为佳，否则可变换转子号和转速达到这个要求。

6) 当不能预知被测液体粘度值时，应试用由小到大的转子和转动变速钮（图5），由慢到快的变化转速顺序来测定粘度值。

Operation：

1) Firstly，Spin the protector pole to right just right under the instrument.

2) Prepare the fluid to be measured ,put it in a beaker or cylindrical container with its diameter not less than 70mm.

3) According to the requested precision of measurement, the temperature of the fluid to be measured should be precisely under control.

4) First estimate the approximate range of viscosity of the fluid to be measured, then select the appropriate rotor and speed according to table of range. Screw the selected rotor into the connecting worm(Turn left to install and right to remove).Turn the elevation knob, slowly lower the instrument, the rotor will gradually dip into the fluid surface, then adjust the leveling speed changing knob making the required speed upward to align with the indication point for speed, release the indicator control rod causing the rotor to rotate in the fluid. After several rotation(Generally 20-30seconds) until the indicator tends to be stable(or make readings at specified time).Press indicator control rod(Caution: 1. Do not use excessive force. 2.When the speed is quite slow, it is not necessary to use control rod. The readings can be directly made), causing the reading to settle, switch off
