Trend Chart Boundaries
The trend chart boundaries (
Y Max
and
Y Min
) can be set automatically
(
AutoScale On
) or manually (
AutoScale Off
) using the menus under the
Options
soft key (Figure 6-9). Auto-scaled (on) boundaries keep all readings within the
trend window. Manually-set boundaries (off) can result in readings outside the
window. Manual boundaries are set using the front panel knob or
[Shift]
ed
numeric keys.
If reading limits are set using the
Math
function, setting
YMax
and
YMin
will
scale (but not change) the limits within the
YMax
and
YMin
boundaries.
YMax
and
YMin
cannot specify a boundary smaller than the
Math
reading limits.
A maximum of 100 readings or decimation points can be displayed in the
trend window.
