Figure 3-22. Peak Reading.
A
peak
reading of

12.247 V occurred 600 ms after Data Storage
was
triggered.
Each
reading
was
made at
15 ms
intervals
(40

Peak
excursions in
mechanical systems may be determined with
4-digit resolution using Data Storage. Up
to
50 readings may be
stored at up to 1000

Using Data Storage, up to 50
channels
may be scanned
in
as little as
50
ms
(1 ms/channel) using
the scanning
plug-in. This provides a
means of economically making dynamic
tests.

Data Storage may be used to allow the DVM to take measurements
at
its
own speed,
independent
of the system's speed
.
Data Storage
is
able to output readings up to 50,000/s.
