RMS 1.

AUDIBLE TESTING

Constraint

Some RMS testing requires "listening" for sounds of motor operation to test equipment

Impact

• Time consuming, accessibility issues
• Subjective test criteria (difficult to calibrate and standardize ear/brain systems)

Design Objectives

• All checkout functions for motorized systems should be automatic using objective criteria
