Job-readiness and assessment field guide
CCST practical 027 assessment: readiness checklist
Direct answer
The candidate can document range and tolerance, choose traceable test points, record as-found and as-left results and distinguish adjustment from repair.
Written for instrumentation candidates practicing how to plan, execute and defend a representative calibration or loop-check task.
Role scope
Instrument identity, service, range, unit, tolerance, reference standard, isolation, test points, adjustment policy and return-to-service criteria.
Skills map
Known reference through sensor or transmitter conversion, loop signal, input value, engineering display and retained calibration record.
Core exercise
Ascending and descending test points remain within declared tolerance with correct direction, unit and repeatability.
Stretch case
Underrange, overrange, hysteresis, drift, wrong unit, reference uncertainty, failed loop power, adjustment limit and return from isolation.
Troubleshooting
A reference, stimulus, instrument, loop, input, scaling, display, tolerance or documentation mismatch.
Portfolio evidence
The result reviewed under current calibration procedure with suitable standards and witnessed restoration.
What should a calibration record contain?
Record instrument identity, range, tolerance, reference equipment, environmental or setup conditions, as-found values, adjustments, as-left values, exceptions and authorization.
Is adjustment the same as calibration?
No. Calibration compares indication with a reference; adjustment changes the instrument. Record both distinctly and retest the full required range after adjustment.
