ULTIPLE
The multiple measurement option (MULTI) allows
the Impulse to take measurements to a succession
of targets. What it does with those measurements
depends upon the MULTI suboption you are in at
the time:
•
DIFF (Difference) compares each measurement
to one set point and reports the difference.
•
CUM (Cumulative) accumulates the
measurements and maintains a running total.
Difference Measurements
Difference measurements calculate the differences
between a succession of targets and a single set
point. You can use either horizontal distance
measurements or slope distance measurements
(Impulse 200 only).
