三、操作步骤：

♦ 将试样固定在V型铁上，从右端插入试棒使一端露出20mm，拴好链绳。

♦ 轻微摇动手轮使V型铁上水平泡处于水平位置。

♦ 打开角度尺紧固栓，转动角度尺使角度尺与副尺归零，拧紧紧固栓。

♦ 顺时针摇动手轮，使V型铁缓慢倾斜，直至试棒滑动为止。

♦ 记录下角度尺示值。

♦ 逆时针摇动手轮，使V型铁水平为止。

♦ 将试棒拉出通信管外露20mm。

♦ 按照以上操作步骤连续9次，计算出9次平均值。（倾斜角度≤14°4′依据JT/T683-2009《通信管道静摩擦系数测量仪》之规定要求）

Third, the operation steps:

♦ Fix the sample on the V-shaped iron, insert the test rod from the right end so that one end is exposed 20mm, and fasten the chain rope.

♦ Slightly shake the handwheel to make the horizontal bubble on the V-shaped iron in the horizontal position.

♦ Open the fastening pin of the angle ruler, turn the angle ruler to zero the angle ruler and the vice ruler, and tighten the fastening pin.

♦ Shake the handwheel clockwise to tilt the V-shaped iron slowly until the test rod slides.

♦ Record the displayed value of the angle ruler.

♦ Turn the handwheel counterclockwise until the V-shaped iron is level.

♦ Pull the test rod out of the communication tube to expose 20mm.

♦ Follow the above steps for 9 consecutive times and calculate the average of 9 times. (Tilt angle ≤14 ° 4 ′ according to the requirements of JT / T683-2009 "Communication Pipe Static Friction Coefficient Measuring Instrument")
