2 5 Fast/slow display
•
When the measured signal is unstable, displayed waveform presents jumping; long-term
observation may cause eye fatigue. Digital Oscilloscope offers the selection of fast/slow
display function, press F3 (F/S), fast display can be switched to slow display, which can
efficiently improve eye fatigue. "Slow" turns to yellow at status bar of interface, means
activated.
•
If press again, switch back to fast display, "Fast" turns to yellow, means fast display
activated.
•
Default fast display after start up.

2 6 Vertical System
•
Press " "to adjust vertical system, default attenuation ratio, that is, preselected frequency
(xxV/div) of adjusting input end after start up presents the status of last shutdown.
•
While selecting DC coupling, as direct current exist in waveform, it may turn to one side,
press "MODE", switch function of "
waveform back to middle position by pressing "
measurement.
2 7 Horizontal system -
•
Press " " to adjust horizontal system, default adjust of sample rate after startup, that is,
xxKSa/S.
•
Press "MODE" then "
(trigger displacement).
2 8 Trigger System -
Trigger function confirms the time of collecting data and displaying waveform for the
oscilloscope.After correctly set up the trigger, the oscilloscope can switch unstable displayed
result to meaningful waveform.
