Knobs Explanation
Use the vertical controls to display signal waveforms by adjusting the vertical
knob, and the knob, and setting the input parameters.
1. Using vertical
knob.
The vertical control changes the vertical position of signal
waveforms in all channels (excluding MATH and REF). The resolution changes
according to the vertical level set. Pressing this knob will clear the channel’s
vertical offset to zero.
2. Using vertical
knob.
The vertical control changes the vertical sensitivity of signal
waveforms in all channels (excluding MATH and REF). If the Volts/Div is set to
“Coarse”, the waveform scales in a 1-2-5 step sequence from 2
mV ,5mv,10mv…to 10 V. If the Volts/Div is set to “Fine”, it scales to small steps
between the coarse settings. Turn the knob clockwise to decrease the vertical
scale, turn the knob counter-clockwise to increase the vertical Volts/Div setting.
You can toggle between “coarse” and “Fine” setting through pressing the
knob.
3. During the vertical positioning, a position message is displayed on the left
bottom of the screen, such as POS:32.4mv in the same color along with the
corresponding channel. The unit is V (Volts).
