  • Calibrate instruments to match required accuracy and operating ranges
  • Diagnose signal, wiring, and device faults using test equipment
  • Read P&IDs, loop diagrams, and manuals to plan safe work steps
  • Document test results, calibrations, and repairs for compliance
  • Support control system checks during startups, shutdowns, and turnarounds
  • Coordinate with operators and electricians to restore stable operation

A day in the life

  1. Review work orders, permits, and drawings, then plan tools and parts
