Chapter 1 Overview RIGOL Chapter 1 Overview Test Preparations The following preparations should be done before the test: 1. Self-test 2. Warm-up (make sure that the instrument has been running for at least 30 minutes) 3. Self-calibration Self-test When the oscilloscope is in power-on state, press the power key at the lower left corner of the front panel to start the oscilloscope. During the start-up, the instrument performs a series of self-test items and you can hear the sound of relay switching.
