Chapter 2 Calibration Procedures
Self-Calibration (Vertical Calibration)
Make sure the oscilloscope has been warmed up for 30 minutes before performing self-calibration.
Then, follow the steps below to calibrate the instrument.
1. Connect all the input channels and external trigger channel of the oscilloscope to the [Trig
Out/Calibration] connector at the rear panel using the BNC One-to-Five Cable.
2. Press Utility at the front panel and select Self-Cal in the first-page menu.
3. Press Start to perform self-calibration (as shown in Figure 6).
4. The self-calibration would last for about 30 minutes (20 minutes for dual-channel models). Restart
the oscilloscope when “Calibration finished, please restart the oscilloscope!” is displayed.
5. Press Acquire, set the Acquisition to “Average” and the Averages to 16.
6. Disconnect the input signals of all the channels to view the offset of the waveform of each channel
at 2mV/div scale. Calibrate again if the offset exceeds 0.5div.
