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.
Volt Scale
Range of Vertical Position
500 μV/div ~ 100 mV/div
±1V
102 mV/div ~ 1 V/div
±10 V
1.02 V/div ~ 10 V/div
±100 V
