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. Click 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.
Press one of the channel buttons CH1, CH2 to open the corresponding channel menu,
and press again to turn off the channel.
If you want to set the vertical position and vertical scale of a channel, please press
CH1, CH2 at first to select the desired channel. Then turn the A or B knob to set the
values.
When one of the
channel buttons is lit
The following practices will gradually direct you to be familiar with the using of the
vertical setting.
1. Press CH1, CH2 panel button to select the desired channel.
2. When one of the channel buttons is lit, you can use the A knob to show the selected
channel waveform in the center of the waveform window. The A knob functions the
regulating of the vertical display position of the selected channel waveform. Thus,
when the A knob is rotated, the pointer of the earth datum point of the selected
channel is directed to move up and down following the waveform, and the position
message at the center of the screen would change accordingly.
Measuring Skill
If the channel is under the DC coupling mode, you can rapidly measure the DC
