7 Over Range: Indicates that the
attenuation and preamp (if installed)
settings are supplying too much

result. Set
Auto Range (On) to clear.
or
<8 Smpl/Pt: Indicates that the
current instrument settings have
reduced the number of
samples/display point to less than 8.
The most accurate averaged
amplitude measurement will be made
when you have at least 8 samples in
each display point.
