PM stands for Preventive Maintenance and CM stands for Corrective Maintenance in the field of instrumentation.

• PM involves scheduled inspections, repairs, and replacements to prevent equipment failure.

• CM involves fixing equipment after it has already failed to restore it to working condition.

• PM is proactive maintenance while CM is reactive maintenance.

• Example: Changing filters regularly (PM) vs. replacing a broken sensor (CM).
