How to Implement Self-calibration
The self-calibration application can make the oscilloscope reach the optimum
condition rapidly to obtain the most accurate measurement value. You can carry out
this application program at any time. This program must be executed whenever the
change of ambient temperature is 5℃ or over.
Before performing a self-calibration, disconnect all probes or wires from the input
connector. Push the Utility button, select Function in the bottom menu, select Adjust.
in the left menu, select Self Cal in the bottom menu; run the program after everything
is ready.
Introduction to the Vertical System
As shown in Figure 3-10, there are a few of buttons and knobs in Vertical Controls.
The 4 channels are marked by different colors which are also used to mark both the
corresponding waveforms on the screen and the channel input connectors. Press one
of the channel buttons to open the corresponding channel menu, and press again to
turn off the channel.
Press the Math button to display the math menu in the bottom. The pink M waveform
appears on the screen. Press again to turn off the math waveform.
The 4 channels use the same Vertical Position and Vertical Scale knobs. If you want
to set the vertical scale and vertical position of a channel, please press CH1, CH2,
CH3 or CH4 at first to select the desired channel. Then turn the Vertical Position and
Vertical Scale knobs to set the values.

The following practices will gradually direct you to be familiar with the using of the
vertical setting.
1. Press CH1, CH2, CH3 or CH4 to select the desired channel.
2. Use the Vertical Position knob to show the selected channel waveform in the center
of the waveform window. The Vertical Position knob functions the regulating of the
