Statistics
Sample Size: selectable between either n = 100 or n = 1,000 samples

unstable least significant digits from display
Math:
all measurement functions, with exception of GATE TIME, totalize in scale mode
and TRIG LVL, may be operated upon by math functions. Offset, Normalize, and
scale may be used independently or together as follows:
Number Value Range: ± 1 X 10 EXP -9 to ± 9 X 10 EXP 9
