Running trend plot.
This mode is used for observing periodic fluc-
tuations or possible trends. Each plot terminates
(if
HOLD is activated) or restarts (if RUN is

Enter Exponent), making it easy to switch be-
tween the mantissa and the exponent.
Press
EXIT/OK to store the new value or
CANCEL to keep the old one.
