Vertical System
The range of bias is related to the vertical scale.
TIP
If the zero-cross voltage of the channel has a larger amplitude offset that exceeds the
adjustable range, please perform self-calibration for the instrument to ensure the
measurement accuracy. For details, refer to
5.11

To Specify the Skew

When using an oscilloscope for actual measurement, the transmission delay of the
probe cable may bring relatively greater errors (zero offset). This series oscilloscope
allows you to set a delay time for calibrating the zero offset of the corresponding
channel. Zero offset is defined as the offset of the crossing point of the waveform and
trigger level line relative to trigger position, as shown in the figure below.
In the "Vertical" menu, click or tap the Ch-Ch Skew input field to set the channel-to-
channel skew time. The available range is from -100 ns to 100 ns, and the default is
0.00 s.

To Turn the Channel Label Display On/Off

The instrument uses the channel number to mark the corresponding channel by
default. For ease of use, you can also set a label for each channel. For example,
Click or tap the channel status label at the bottom of the screen. Then the Vertical
menu is displayed. Click or tap the Label on/off switch to turn the label display on or
off. You can also click or tap the label input field to input a specific name for the
channel label with the pop-up keypad.
