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
