Multipoint Options
1
662 Multi-Session Option
•
Allow
s a recorder to store up to 16 measurement sessions
•
Each session can consist of up to 6000 events, increasing the event storage to 96,000
1663 TCP/IP Option
•
Enables Ethernet-equipped instruments to communicate via Internet
1950 Multipoint Base
Each 1
94X acquisition system requires a base unit.
The 1950 base provides connection points to your
power system. The 194x Acquisition unit can be
removed for maintenance or calibration, without
disturbing the distribution system. For systems
using fixed, 5A CT’s the base provides terminals for
voltage and current. For systems using clamp-on
CT’s, the base prov
ides voltage terminals
.
Software completes the system
There are two software packages available for the
Multipoint Power Recorder. Both packages provide
seamless communication, with graphical display
of power system parameters and the ability to
manage power survey data.
Power analyzer system software
•
Offers optional Report Writer Software
•
Offers Alarming and Polling Option
Scenario software
•
Includes fac
ilities for comparing trends from
multiple databases
•
Calculates a Power Quality Index - a single figure
of merit that characterizes the overall perform
-
anc
e of a power system
. The Power Quality
Index allows you to trend system performance
over time and determine whether a system is
improving or degrading.
With Multipoint high-speed models 1

948 gather
detail on impulses as short as 500 ns.
