ISA CCST Level II study plan
ISA CCST Level II · Give each week a clear focus.
8 weeks · About 7 hours per week
Calibration, maintenance, repair and troubleshooting
Map every calibration and troubleshooting subtopic in Domain 1 to a personal confidence rating so weak areas are identified before study begins
Explain how zero, span, and linearity errors are distinguished and how each is corrected on a typical 4-20 mA transmitter
Trace a complete calibration chain from process variable to control system input and state where uncertainty enters at each step
List the routine maintenance tasks and inspection intervals commonly applied to transmitters, control valves, and impulse lines
Your checkpoint
A one-page Domain 1 topic map with confidence ratings and a written calibration-chain diagram showing at least five uncertainty sources
Calibration, maintenance, repair and troubleshooting
Diagnose loop faults from symptoms such as frozen readings, erratic signals, saturation, and ground loops, and rank the likely causes for each
Describe the correct use of a loop calibrator, HART communicator, and multimeter during fault isolation without disturbing the process
Explain how to perform a five-point calibration check, document as-found and as-left data, and decide when a device needs adjustment versus replacement
Identify safety and process-isolation steps required before opening a loop or removing an instrument from service
Your checkpoint
A troubleshooting decision tree covering at least six fault symptoms with ranked causes and the test used to confirm each
Calibration, maintenance, repair and troubleshooting & Project start-up, commissioning and loop-check
Work through valve-positioner and actuator repair scenarios, including stroking, bench-set, and travel-stop adjustment
Explain loop-check sequencing from field device to DCS and describe what each check proves
Prepare a pre-commissioning checklist for a single instrument loop covering wiring, grounding, polarity, and configuration
Compare point-to-point verification with full loop verification and state when each is appropriate
Your checkpoint
A completed sample loop-check package for one hypothetical flow loop, including checklist, test steps, and acceptance criteria
Project start-up, commissioning and loop-check
Describe cold and hot commissioning activities and the order in which they are performed on a new process unit
Explain how to verify analog inputs, analog outputs, and discrete signals against the cause-and-effect or I/O list
Outline how interlocks and safety functions are functionally tested and how test results are recorded and witnessed
Identify the documentation typically required to close out commissioning, such as punch lists, test records, and turnover packages
Your checkpoint
A commissioning sequence for a two-loop skid with interlock, listing test steps, records generated, and sign-off points
Project organization, planning and documentation
Identify the core project documents, including P&IDs, instrument index, loop drawings, datasheets, and I/O lists, and state what each controls
Explain how an instrument index and I/O list stay synchronized with P&ID revisions and why drift causes field errors
Describe how scope, schedule, and budget baselines are set and how change orders are raised and tracked
Draft a revision-control procedure for instrument drawings that names approvers and distribution rules
Your checkpoint
A document register for a small project listing at least eight document types, their owners, and revision-control rules
Project organization, planning and documentation
Build a work breakdown structure for an instrumentation installation package and map it to a simple schedule
Explain how to estimate labor and material for instrument installation and where estimates commonly fail
Describe how vendor submittals, factory acceptance tests, and shipping schedules are tracked against the project plan
Outline a project closeout file, including as-builts, test records, and training documentation
Your checkpoint
A one-page WBS with schedule bars and a short written rationale for each estimate assumption
Administration, supervision or management
Explain the supervisor's role in assigning work, verifying competence, and documenting performance on instrument crews
Describe how to run a toolbox talk and a pre-job safety review for a loop-check or calibration task
Outline how to manage contractor interfaces, permits, and coordination with operations during commissioning
Identify the recordkeeping and reporting obligations that fall on a lead technician or supervisor
Your checkpoint
A supervisor's weekly routine document covering crew assignment, safety briefing, progress reporting, and escalation triggers
Calibration, maintenance, repair and troubleshooting & Project start-up, commissioning and loop-check & Project organization, planning and documentation & Administration, supervision or management
Review all four domains using the topic map and confidence ratings from week 1, closing remaining gaps
Practice timed questions across every domain and analyze errors by domain and subtopic
Rehearse explaining a troubleshooting decision, a loop-check sequence, and a schedule trade-off aloud as if to an examiner
Confirm exam-day logistics and finalize a last-week review sheet of formulas, standards, and terminology
Your checkpoint
A scored practice set with an error log by domain and a one-page final review sheet
Milestones
Week 2: Can diagnose at least six loop fault symptoms from memory and name the confirming test for each without notes
Week 4: Can walk through a complete loop check and commissioning sequence for a two-loop skid, naming records and sign-offs at each stage
Week 6: Can build a WBS and document register for a small project and explain revision control and change orders in plain terms
Week 8: Scores at or above 80 percent on a mixed-domain timed practice set with no domain below 70 percent
