Press the Vertical Scale softkey to specifies how the current vertical scale is determined.
Default
: Set the scale to equal the measurement range. For example, for the DCV
measurement function, the vertical scale will be set as -200 mV to 200 mV when the
present range is 200 mV.
Manual
: Allow you to configure the scale either as
High
and
Low
values or as a
Span
around a
Center
value. For example, a scale that goes from a Low of -50 mV to a High
of 100 mV could also be specified as a Center of 25 mV with a Span of 150 mV.
Auto
: Automatically adjusts the scale to appropriately fit the line currently shown on
the screen.
Press the Autoscale softkey to automatically set the vertical scale once.
Press the Clear Readings softkey to clear reading memory and redraw.
Histogram
Press the front panel
