Which term refers to steps including measurement, assembly, and testing?

• A. Installation Sequence
• B. Track/Rail Measurement
• C. Power Source
• D. Battery Backup

Answer: (A)

The steps that cover measurement, assembly, and testing form the installation sequence. This term represents the organized progression used when putting in an escalator or moving walk: first you measure and lay out the site to ensure everything will fit and align correctly, then you assemble the components according to the plan, and finally you perform tests to verify safe and proper operation before the equipment is put into service. This sequence keeps installation orderly and compliant with safety and performance standards.

Track/rail measurement is just one task within the process, not the whole sequence. Power source and battery backup describe electrical components or capabilities, not the overall installation steps.
