The oscilloscope must have operated continuously for thirty minutes at the service
temperature. You must run the Auto-calibration from the "Utility" menu if the service
temperature varies by more than 5°C. The oscilloscope must be within the factory
calibration range. All specifications are guaranteed except those marked "typical"
