Self-Calibration
The Self-Calibration adjusts the internal circuitry to get the best accuracy. Use these
functions to calibrate the vertical and horizontal systems. For maximum accuracy at
any time, run this calibration if the ambient temperature changes by 5°C or more.
Disconnect any probes or cables from all channel inputs, otherwise failure or
damage to the oscilloscope may occur. Press Utility → Self-Cal to enter the
self-calibration interface as follows. Press “RUN/STOP” key to start the operation and
press “AUTO” key to exit the system.

Self calibration
NOTE: The oscilloscope must have been working or warm-up at least
30-minutes before running self-calibration to get best accuracy.
