This module addresses the calibration, testing, and operational validation of critical pressure instrumentation. 

Training focuses on four primary gauge categories: Depth Gauges, Caisson Gauges, Life Support System Gauges, and General Indicating Gauges. 

The primary operational objective is to ensure that all tested equipment is verified as fit for service in compliance with statutory safety tolerances. Accuracy validation relies on a certified Master Gauge—a precision reference standard traceable to international standards, utilized to adjust, calibrate, and verify working instruments prior to deployment
