Modes
Autorange (Typical) Autorange mode positions and sets the vertical and horizontal scales to between
30% and 60% of full screen. After 500 ms, the process repeats if the signal
amplitude or period changes. The lower limits of Autorange are 50 mV/div and
100 ms/div. Autorange is the default mode.

Manual The scope switches to manual operation when any control alters the waveform
display. D D D
Line Test
H Will monitor a 45 to 65 Hz power waveform on CH 1 and check for variations
in amplitude and frequency. Abnormal events, such as spikes, drop-outs, and
substantial frequency variations, will be captured and counted. D D
