三，通信管内壁静摩擦系数测试仪操作步骤：
♦ 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 specimen on the V-shaped iron, insert the test rod from the right end, expose one end to 20mm, and lick the chain.
♦ Slightly shake the handwheel so that the horizontal bubble on the V-shaped iron is in a horizontal position.
♦ Open the angle ruler and turn the angle ruler to zero the angle ruler and the secondary ruler and tighten the fastening bolts.
♦ Shake the handwheel clockwise to slowly tilt the V-shaped iron until the test stick slides.
♦ Record the angle ruler value.
♦ Shake the handwheel counterclockwise to level the V-shaped iron.
♦ Pull the test rod out of the communication tube and expose it to 20mm.
♦ Calculate 9 average values according to the above steps for 9 consecutive times. (The tilt angle ≤14°4' is based on the requirements of JT/T683-2009 "Communication Pipe Static Friction Coefficient Measuring Instrument")
