Summary

CCST question

An instrument location plan shows the __________ of each instrument: 

A. location and wiring plan
B. location, elevation, and tag number
C. specification number and tag number
D. location, specification number, and elevation
 
CCST Answer

The answer is B, “location, elevation, and tag number.” Instrument location plans are valuable drawings when installing new systems. They show important physical characteristics about the instrument so that they can be installed easily and efficiently. The tag number identifies the instrument to be installed. Along with the location and elevation, the installer will know exactly where the instrument should be located, even before going to the specific location.
