hen preparing the CHAIN scanner for larger diameter pipes, the scanners sition must be adjusted, to avoid helicoidal movement as much as possible. herwise, go directly to step 8.r larger diameter pipes, adjust the scanners position. Do the following:

Measure the distance between the side of the wheel of the module and the weld (for example, 100 mm).Rotate the module 180 around the pipe.Measure again the distance between the side of the wheel of the module and the weld (for example, 120 mm).Unlatch the chain mechanism while keeping pressure on the latch, to make sure that the CHAIN scanner stays at its current position.Move the module to position it at the same distance to the weld as measured in step 7.a (as per this example, we would move the module 20 mm toward the weld).Latch the chain mechanism.Return the chain scanner to its original position (180).Repeat steps 7.a to 7.g until the position is repeatable within an acceptable range.
