When setting up a tripod and builder's level, what is the first step?

• A. Calibrate
• B. Level the device
• C. Extend the legs
• D. Align with North

Answer: (B)

The first thing to do is establish a true horizontal reference for the instrument. Leveling the device centers the bubble in the level vial and uses the leveling screws (or the tripod legs) to bring the instrument into a perfectly horizontal plane. This is essential because any tilt distorts readings along the vertical, making elevation and alignment inaccurate. Calibrating is something you do when you suspect the instrument’s internals are off or after transport, not the immediate first setup step. Extending the legs helps you reach a comfortable height, but you still level the device afterward. Aligning with North is an orientation task you’d do after leveling if you need a known directional reference, not the initial step. So leveling the device is the correct starting action.
