When using laser alignment equipment, where should the transmitter be mounted?

Mounting the transmitter of laser alignment equipment on a stationary machine is the correct approach because it serves as a stable reference point from which to measure the alignment of the other machine. When the transmitter is securely positioned on a non-moving part, it allows for precise alignment readings without the influence of machine vibrations or movements that may occur during operation.

This method ensures that the measurements taken between the stationary machine and the rotating machine (which can be adjusted during the alignment process) are accurate. Proper alignment is crucial for the efficient operation of machinery, as it reduces wear and tear, minimizes energy consumption, and extends the life of the components involved.

Using the transmitter in this way allows the technician to identify any misalignment issues effectively and adjust the rotating machine as needed. The other options present scenarios that either compromise the measurement accuracy or introduce unnecessary complexity to the alignment process.
