Page 13: Automatic Calibration
You can run the routine at any time but you should always run the routine if the ambient temperature changes by 10°C or more. For accurate calibration, power on the EM101N and wait twenty minutes to ensure it is warmed up. Calibration mainly includes simulation channel calibration, trigger voltage of trigger circuit calibration and non-linear calibration of horizontal base line deviation. -

Note: For better comparison and identification, each channel and waveform is marked in different color. The EM101N can display multiple waveforms simultaneously, but only one waveform is allowed to display at top. The top channel is called current channel displayed as 3.2.2 Channel Attributes &... - Page 17 Oscilloscope presents the acquired data on the screen. Go to Trigger, the following screen will appear: The EM101N applies edge trigger, which is the most commonly used and effective trigger method. A clear majority of applications apply this trigger method to trigger waveform. An edge trigger determines whether the Oscilloscope finds the trigger point on the rising/falling/dual edge of a signal.
