To Adjust the Vertical Scale
The vertical scale can be adjusted in Coarse or Fine mode.
Coarse adjustment (take counterclockwise as an example): set the vertical scale in 1-2-
5 step namely 500uV/div, 1 mV/div, 2 mV/div, 5 mV/div, 10 mV/div …10 V/div.
Fine adjustment: further adjust the vertical scale within a relatively smaller range to
improve vertical resolution. For example: 2 V/div, 1.98V/div, 1.96V/div, 1.94 V/div …1
V/div.
If the amplitude of the input waveform is a little bit greater than the full scale under the
current scale and the amplitude would be a little bit lower if the next scale is used, fine
adjustment can be used to improve the amplitude of waveform display to view signal
details.
Press the CH1 button on the front panel; then press the Adjust softkey to select the
desired mode. Turn the VERTICAL Variable Knob to adjust the vertical scale (clockwise
to reduce the scale and counterclockwise to increase).
The scale information in the channel label at the right side of the screen will change
accordingly during the adjustment. The adjustable range of the vertical scale is related
to the probe ratio currently set. By default, the probe attenuation factor is 1X and the
adjustable range of the vertical scale is from 500uV/div to 10 V/div.
Note: push the VERTICAL Variable Knob to quickly switch between Coarse and Fine
adjustments.
To Adjust the Vertical Position
Turn the
VERTICAL Position Knob
to adjust the vertical position of the channel
waveform. Turn the knob clockwise to increase the vertical position and the channel
waveform moves up while counterclockwise to reduce the vertical position and the
waveform moves down. Push the knob to set the vertical position of the channel
waveform to zero.
During the adjustment, the vertical position information Volts Pos displays at the bottom
of the screen. The table below shows the range of vertical position according to the volt
scale.
