2.6.2 The Using of the Vertical Position knob and
Volt/div knob in the vertical system
●
Vertical
POSITION knob
1. Use the Vertical POSITION knobs to move the channel waveforms up
or down on the screen. This button's resolution is variety as per the
vertical scale.
2. When you adjust the vertical position of channels waveforms, the vertical
position information will display on the left bottom of screen. For example
Volts Pos=24.6mV.
3. Press the vertical POSITION knob to set the vertical position to zero.
●
Volts
/div knob
1. Use the Volts/div knobs to control how the oscilloscope amplifies or
attenuates the source signal of channel waveforms. When you turn the
volts/div knob, the oscilloscope increases or decreases the vertical size
of the waveform on the screen with respect to the ground level.
2.6.3 Math Functions
Math shows the results after +,-,*and FFT operation of the CH1 and CH2.
Press the MATH button to display the waveform math operations. Press the MATH
button again to remove the math waveform display.

Introduction
2. When you press the Volt/div Knob, you can switch Volt/div option
between Coarse and Fine. The vertical scale is made sure by the 1-2-5
step in the Coarse. Increase in the clockwise, reduce in the anticlockwise.
In the fine mode, the knob changes the Volts/Div scale in small steps
between the coarse settings. Increase in the clockwise, reduce in the
anticlockwise.
