Chapter 4 Calibration
By performing the calibration program, the oscilloscope can quickly reach the
optimum working state and acquire the most accurate measurement values. You can
execute the calibration program at any time. Calibration must be performed when the
environment temperature variation is up to or more than 5℃.
Note:
Before performing the self-calibration program, make sure that the oscilloscope has
been running or warmed up for at least 30-minutes.
Steps:
1. Disconnect all the probes or cables from the input connectors.
2. Press Utility  Self-Cal and the self-calibration interface as shown in the figure
below is displayed.
3. Press RUN/STOP to start the self-calibration. The oscilloscope will calibrate the
parameters of the vertical system (CH1, CH2, CH3, CH4 and Ext), horizontal
system and trigger system automatically to guarantee that the specifications can
always meet the specifications in different environment.
4. After the self-calibration finishes, "Calibration Finished" is displayed, as shown in
the figure below. You can press RUN/STOP to exit the self-calibration program.
