[0013] Step 2: The transmitter emits light. According to the position of the light, move the transmitter up and down until the light hits the reflector on the end face of the anti-ropes pulley. Turn off the light and tighten the locking screw to fix the transmitter on the steel ruler.

[0014] Step 3: The transmitter emits light again to read the value on the ruler; and the value on the transmitter;

[0015] Step 4: According to the value on the steel ruler and the value of the transmitter, get the inclination angle of the anti-ropes.
