2 topics across all disciplines.
Instrument installation and loop checking — where most readings go wrong
Hook-up drawings, why impulse lines must slope the right way, what a manifold is for, and the commissioning sequence that catches problems before the plant does.
Calibration and accuracy — what a certificate actually proves
The difference between ranging a smart transmitter and calibrating it, why as-found readings matter more than as-left ones, what turndown does to accuracy, how hysteresis hides from a one-direction check, and why traceability is what turns a number into evidence.
