Question

Quizplus · Accepted Answer

Instrumental errors are those errors that arise due to imperfections or faults in the instruments used for measurements. Sluggish needle, blunt pivot joint, and the plane of sight not being vertical are all examples of instrumental errors because they are related to the physical condition or adjustment of the instrument itself. Inaccurate centering, however, is not considered an instrumental error but rather an operational error, as it is related to the procedure of using the instrument rather than a fault in the instrument itself.
