How to Set the Vertical System
The VERTICAL CONTROLS includes three menu buttons such as CH1, CH2, CH3, CH4 and
Math, and Vertical Position, Vertical Scale for each channel.
Setting of CH1 - CH4
Each channel has an independent vertical menu and each item is set respectively
based on the channel.
To turn waveforms on or off (channel, math)
Pushing the CH1, CH2, CH3, CH4, or Math buttons have the following effect:
• If the waveform is off, the waveform is turned on and its menu is displayed.
• If the waveform is on and its menu is not displayed, its menu will be displayed.
• If the waveform is on and its menu is displayed, the waveform is turned off and its
menu goes away.
The description of the Channel Menu is shown as the following list:

Step by 1 – 2 – 5. Match this to the probe
attenuation factor to have an accurate reading of
vertical scale.
MeasCurr
YES
NO
If you are measuring current by probing the
voltage drop across a resistor, choose YES.
A/V (mA/V)
V/A (mV/A)
Turn the M knob to set the Amps/Volts ratio. The
range is 100 mA/V - 1 KA/V.
Amps/Volts ratio = 1/Resistor value
Volts/Amp ratio is automatically calculated.

Get full bandwidth.
Limit the channel bandwidth to 20MHz to reduce
display noise.

It can reduce the circuit load caused by the
interaction between the oscilloscope and the
circuit under test.
1. To set channel coupling
Taking the Channel 1 for example, the measured signal is a square wave signal
