During crater profile measurement, if the target triangle on the rod is visible, you should

Precise alignment with the measurement reference is what this item is about. The target triangle on the rod serves as a sighting cue to confirm you’re at the proper position for crater depth reading. If you can see the triangle, you’re still in the alignment window and should move one more step toward the stanchion to bring the measurement tip onto the correct position for the next reading. This keeps the measurement distance consistent and minimizes parallax or positioning errors. Stopping immediately would leave you at the wrong location for the next reading. Moving to the left would take you off the intended alignment axis. Ignoring the cue would skip a necessary step and degrade accuracy.
