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.

Before running this procedure, do these steps:

1. Disconnect any probes or cables from all channel inputs, otherwise failure or

damage to the oscilloscope may occur.

2. Push the Utility button and select Self-Cal.

The self-calibration menu is displayed as Figure 2-92.

NOTE:

The oscilloscope must have been working or warm-up at least 30-minutes before

running self-calibration to get best accuracy.
