Calibration Lab
Five-point checks, zero and span - prove the instrument tells the truth.
Difficulty: IntermediatePlay time: about 12 minutes
Workplace narrative
A pressure transmitter has drifted. Run a five-point calibration with a deadweight tester, adjust zero and span, and certify the loop before the plant accepts it.
