PA9PLUS
DESCRIPTION
The new Megger PA9Plus is the latest innovation of
the successful PA-9 Power Quality Analyzer platform. It
incorporates newly enhanced key features including a
faster Digital Signal Processor (DSP) to support continually
evolving capabilities, a full 12 MB of nonvolatile internal
memory and standard auxiliary power input capabilities.
To address worldwide requirements and applications,
the PA9Plus is CE marked, supports several international
languages, and adheres to applicable European and
North American standards (EN50160, IEC61000-4-15,
IEEE1159, IEEE519), including automatic phase lock loop
synchronization of input frequencies ranging from 20 Hz
to 70 Hz, flicker measurements and recording, and out of
limits/frequency trending.
The optional removable memory capabilities allows
internally recorded data to be copied directly to an external
standard compact flash card using the same technology
available with most of today’s digital cameras. This means
that without a computer on site, data can be manually
or automatically copied from the instrument to external
memory cards, increasing the effective instrument memory
storage to the size of the card used. Similarly, new
configuration setups may be programmed in the same,
simple manner.
The standard software has been enhanced to fully support
n
Includes enhanced MEGPA9IEC software
for instrument configuration,
communications, data retrieval and
charting/reporting
the new functionality and is included at no cost with every
PA9Plus purchased. A new, optional report generator
has also been developed to support your customized
documentation/reporting needs.
The PA9Plus records power quality and power flow
information simultaneously. The recorded information can
be viewed via the built-in graphics display, downloaded to
a computer using the serial interface and optional modem,
or transferred using the optional removable Flash Memory
Module.
Megger offers a comprehensive line of self-powered (no
batteries required) flexible and clamp-on current probes
for use with the entire PA-9 Series. If you would prefer to
use your own probes, simply order the applicable Megger
adapter.

Versatile Data Recording Modes
For ultimate flexibility, the user determines how data is
recorded:
n
Continuous Recording – the PA9Plus records all selected
parameters (i.e. minimum, average and maximum values
of voltage/ current, power parameters, etc.) with date
and time stamp for each storage interval.
n
Exceedance only Recording – the PA9Plus only records
abnormal events based on user selected limits. This
technique saves memory and allows longer recording
times.
n
Wraparound or “Moving Window” – when memory is full,
the power analyzer automatically writes over the oldest
data. This first-in, first-out process guarantees that the
most recent data is always recorded and available.
n
Transfer to External Memory Card – manual and
automatic transfer capabilities. This card is available from
Megger.
APPLICATIONS
Using experience gained from supplying thousands of
solid state recorders to hundreds of utilities, industrial, and
service companies around the world, Megger designed
the PA9Plus to be the most versatile instrument available

FEATURES AND BENEFITS
n
The maintenance-free design provides significant time
savings with each installation. With the capability of
preprogramming up to 64 internal setups in advance, the
PA9Plus is always ready. Simply select from any of the
sample or user-defined recording configurations/ setups
and begin the analysis. Setups may also be imported via
the removable memory option.
n
The PA9Plus is typically self-powered from the
unregulated voltage on the first input channel (90-600 V
ac at 20-70 Hz, or 110-600 V dc). This means that it can
be used virtually anywhere since a well-regulated 120
or 240 V ac power source is not required. The auxiliary
power input feature allows an alternative to self-power
from a 10th, non-recording input source, effectively
eliminating the small burden required to power the
PA9Plus. This feature also negates any turn-on delays
associated with some monitoring applications such as
high-speed motor start studies.
n
A large, backlit LCD confirms setup information and
real-time status, phasors, frequency, harmonics, harmonic
power, voltage, current, per phase and total power/
energy data, and minimums/maximums by phase.
From data already recorded, charts of trended voltages,
currents, waveform graphs, and reports of historical outof-limits information by event type may be viewed.
n
The newly enhanced MEGPA9IEC software for setup,
configuration, communications, charting, and reporting
continues to be included at no cost with every PA9Plus
purchased. Optional enhanced report generation
software, METREPORT, may also be purchased
separately for creating custom-tailored reports.
MEGPA9IEC SOFTWARE FOR WINDOWS
MEGPA9IEC is a simple, intuitive, menu-driven software
package for use with both the new and existing PA9Plus
Power Quality Analyzers. This software, provided at no
charge to Megger customers, incorporates an instrument
firmware upgrade feature for field-updating your PA9Plus
to the newest capabilities.
Retrieve Only the Data That Matters
MEGPA9IEC now includes a remote test log function to
preview charts, events, reports, and waveforms prior to
actual download. This preview function also includes the
capability to select and download only the data content and
time frame relevant to the investigation being performed,
thus dramatically reducing the download time required.

Quick Recorder Setup
With Megger MEGPA9IEC, the PA9Plus can be set up for
different test conditions in a matter of seconds. By simply
filling in a form, the operator chooses which phases to
record, the corresponding out-of-limit values, which
statistics to save (minimum, RMS, and/or maximum), etc.
For added convenience, the software provides default
configurations for use as templates in creating customerspecific setups. Further, the software computes the
maximum recording time based upon the selections made.
Once the PA9Plus is configured for a test, it will retain this
setup information until changed. Setup files may also be
saved for re-use, or transported amongst instruments using
the optional removable memory card.

dramatically reduces the time for problem analysis and
identification. An important feature allows you to zoom
in/zoom out of particular windows, as well as to copy
and paste data directly from the chart to a third-party
spreadsheet, database, or analysis program. The scan-line
feature provides exacting data and timing information
at any particular point in the chart, thus removing all
guesswork and approximation in the investigation. In
addition, you can graphically view vector information and
relationships for any demand interval, as well as modify the
look of the chart axis and title information. All charts and
graphs may be printed directly to your local or network
printer, and copied and pasted to third-party applications.
