The oscilloscope must have been operating continuously for thirty minutes within the
specified temperature. You must perform the « Do Self Cal » operation through the
“Utility”
menu, if the operating temperature changes by more than 5°C. The oscilloscope must be
within the calibration interval. All specifications are guaranteed unless note "typical"
