1. Use vertical position knob so that middle displa
y
of waveform signal in the window. Vertical displa
y
position of signal can be controlled by vertical
position knob
.
Ground mark moves vertically with waveform whe
n
rotating vertical position knob
.
Measurement knack
You can observe difference between waveform
and signal ground to measure DC component
of signal quickly if adopting DC channel
coupling mode. DC components in the signal
will be filtered if adopting AC coupling mode
. You can also display AC component of signal
by higher sensitivity conveniently
.
Vertical position of double analog channels shall be
restored to short-cut key of zero pointnamely
,
SET TO ZERO
.
The key is to return vertical displacement/horizontal
displacement/hold off position to zero point
(or middle point)
.

2 Alter vertical setup and observe alternation of
status information. You can determine variation of an
y
vertical gear by status bar below waveform window
.
Ver tical gear of “volt/grid” can be altered by rotatin
g
vertical scale knob to show corresponding variation for
channel gear display which corresponds to status bar
.
User can press [CH1], [CH2] , [MATH] and [REF] to
display operation menu, mark, and waveform and
gear status information of corresponding channels
