Selects a value according to the probe attenuation
factor so as to ensure correct vertical readouts.
Reduce bandwidth to 6MHz when using a 1X probe.

Inverts the waveform relative to the reference level.
Coupling
 If the channel adopts a DC coupling mode, you can quickly measure the DC
component of the signal by observing the difference between the waveform and
the signal ground.
 If the channel adopts an AC coupling mode, the DC component in the signal is
filtered. By this mode, the AC component of the signal is displayed at a higher
sensitivity.
 If the channel adopts a GND coupling mode, cut off the input signal. Inside the
channel, the channel input is connected with a zero volt reference electric level.
Fine Resolution
In the fine resolution setting, the vertical scale readout displays the actual VOLTS/DIV
setting. The vertical scale changes only after you adjust the VOLTS/DIV control and set
to coarse.
Remove Waveform Display
To remove a waveform from the screen, first push the menu button to display the
vertical menu, then push again to remove the waveform. A channel waveform which is
unnecessary to be displayed can be used as a trigger source or for math operations.
4. MATH MENU: Display the waveform math operations. See the table below for
details.
The MATH menu contains source options for all math operations.
