Self calibration The self calibration routine helps optimize the oscilloscope signal path for maximum measurement accuracy. You can run the routine at any time but should always run it if the ambient temperature changes by 5 ℃ or more. For a more accurate calibration, please power on the oscilloscope and wait for 20 minutes until it has adequately warmed up. To do self calibration, follow these steps: 1. Ensure that no input signal is input, otherwise it may damage the instrument. 2. Press Menu button to select the self calibration function.
