- There was no factory-mandated periodic “calibration” like for measurement instruments. If you rely on dimensional accuracy, a 12-month interval is a common practice in quality systems. Otherwise, calibrate or verify only after service, transport, or when accuracy issues are observed.

A Keysight (Agilent/HP) 7550A Plotter doesn’t lie—but it will expose lazy calibration. High‑accuracy measurements demand calibration performed by technicians who understand the 7550A, the specification limits, and the standards behind them.
Expert calibration verifies performance against traceable references, flags drift before it becomes failure and documents every adjustment. This isn’t box‑checking or sticker‑slapping. Its precision enforced. If your work depends on numbers you can defend, Rogue Calibration helps find the right calibration service provider for you.
