A typical shift

Start with a safety meeting and the work permits: in a live plant you cannot open anything without one. Then the calls. A flow transmitter is reading high and nobody trusts it, so you pull it, bench-check it against a known standard, and either recalibrate or replace it. A control valve is hunting, and you spend two hours deciding whether it is the valve, the positioner or the tuning. Between jobs there is planned calibration work, records to sign, and the slow accumulation of knowing which instruments in the plant lie.
