Warming up
Before performing the adjustment procedures, you must let the oscilloscope
and other test equipments warm up for at least 30 minutes in an ambient
temperature between 20 °C and 30 °C. Adjustments performed prior to
warm-up or outside this temperature range may result in poor performance.
