Question

Lasers and ODI must be checked ______ and must be within ______

a) Annually, 1 mm
b) Quarterly, 2 mm
c) Monthly, 3 mm
d) Weekly, 4 mm

Answer 1

The regular maintenance and accuracy checks for lasers and ODI depend on industry standards or manufacturer's recommendations, and while Quarterly, 2 mm seems plausible, the precise answer varies based on the equipment and project requirements.

Step-by-step explanation:

The question is referencing the regular maintenance and accuracy checks for lasers and Optical Distance Indicators (ODI), which are precision instruments often used in engineering, surveying, and construction. The accuracy of these devices is critical for the quality of measurements and work being performed. The answer to this question depends on specific industry standards or the manufacturer's recommendations. In many cases, there is no one-size-fits-all answer, and the frequency of checks and the acceptable tolerance range may vary based on the equipment and the project requirements. However, assuming this question is based on a specific standard, a likely answer could be 'b) Quarterly, 2 mm,' but this should be confirmed with the equipment manual or regulatory standards pertinent to the context in which the equipment is used.
