During the laser alignment process, what must be done with the target sensor to ensure accurate readings?

The correct approach during the laser alignment process involves rotating the target sensor 180 degrees to ensure accurate readings. This method is critical because it allows for the verification of the sensor’s alignment and compensates for any potential errors in the sensor's initial position. When the sensor is rotated, the laser's path is re-evaluated under a different angle, helping to confirm that the readings are consistent and reliable.

This step is particularly important because it checks for alignment discrepancies and helps adjust for any minor inaccuracies that could arise due to misalignment or imperfections in the sensor's positioning. By rotating the sensor 180 degrees, the technician can confirm that the readings remain stable and accurate from both orientations, ultimately ensuring the alignment is precise before any adjustments are made to the machinery.

In contrast, keeping the sensor stationary would not challenge its initial reading, which might lead to undetected errors. Moving it only once may not provide adequate verification of alignment, and rotating it 90 degrees would not sufficiently test the sensor’s precision as comprehensively as the 180-degree rotation does.
