b) Using Vertical “Position” Knob and “Volt/div” Knob
■
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=24.6 mV”.
3. Press the vertical “POSITION” knob to set the vertical position to zero.
■
“Volt/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. 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.
c) Math Functions
Math shows the results after +,-,*, / and FFT operations 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.
