blocked, depth value of each pipe shall be the same; otherwise the
depth value of blocked pipe may be smaller than that of other pipes.
In this case, press the edit box behind this pipe and input actual depth
value.
If pipe is blocked, take out transducer cable in this pipe from
lifting device, when other profile tests reach the blockage position
(prompt message will pop up in system), place the transducer cable in
this pipe into lifting device and lift together.
After have saved the first test point, all transducers shall be lift

record data of all test points automatically. Do not lift or put down
transducer too fast nor suddenly accelerate or decelerate.

When lift or put down transducer too fast and system cannot
respond in time, a dialogue box prompting user to place it back to a
