Testing Preferred method of testing is with a calibrated air flow test bench. This allows quantifiable results to be obtained that can be documented. All test specifications are found in the repair manual

Subjective Breathing Test Place venturi switch in minus “-” position Check for strong purge Inhale slowly but deeply –Should deliver air with little effort, smoothly, without “fluttering” –Should not freeflow or leak Should exhale smoothly

Immersion Test Submerge pressurized regulator in a test tank of clean water Observe for air leaks NOTE: Do not confuse bubbles from trapped air with a true leak. If there is an air leak, bubbles will come out in a constant stream.

Common Problems Air Leak or freeflow –MP too high –Lever too high –Crown orifice maladjusted or damaged –LP seat damaged Weak purge –Lever too low High opening effort –Crown orifice maladjusted
