Zero Level. If you select the VDC meter function, the zero level is
located at the horizontal centerline of the graticule; for all other
meter functions, the zero level is the bottom of the graticule.
Reference Level. If the Rel
D
function is turned on, the Rel
D
baseline
value is marked along the left side of the graticule.
VOLTS/DIV Rocker. Use the VOLTS/DIV rocker to set the meter range
and control the vertical scale of the data logger plot. If you change
the vertical scale while the data logger is running, you will cause a
vertical discontinuity; old data is not rescaled to match the current
setting. However, if you change the vertical scale while the HOLD
function is active, the entire waveform is scaled to match the current
setting.
SEC/DIV Rocker. Use the SEC/DIV rocker to control the scroll speed
of the data logger plot. When you change the scroll speed, existing
data in the data logger plot is erased.
