1. OVERVIEW
The EPM 2000 Digital Power Meters offer comprehensive Three-Phase Electrical
Instrumentation and load management facilities in a compact and rugged package.
To get the best out of your investment, we suggest that you take a few moments to review this
Manual. This Chapter contains the main operating instructions. The remaining Chapters explain
the Installation and Setup steps before the Meter is ready for use.
The EPM 2000 is a universal meter. Before use, please program the SYS (measurement system
configuration), PT and CT ratios through the front panel keys. Otherwise, it will read your system
incorrectly.
GE stands behind your EPM 2000 products with complete User Support and Service. If the need
arises, please do not hesitate to contact us at 1-888-GE4SERVICE (1-888-434-7378).
Figure 1-1. The EPM 2000 Digital Power Meter.

GE Multilin Sub Meters
1.1. Physical Description
FRONT: The front panel has 3 rows of 4 digits / characters each, with auto scaling “K” kilo, “M”
Mega and “-” negative indications. The “kilo” and “Mega” indications lit together show Giga
readings. Load bar graph on right side of the display gives the indication of consumption in terms
of the %Average load. Five smart-keys make navigating the parameter set very quick and
intuitive for viewing data and configuring (Setup) the EPM 2000.
REAR: The voltage and current terminals and the communication port are located on the back of
the meter.
1.2. Front Panel
The front panel contains the following indicators and controls:
• Three rows of Numeric displays, 4 digits each that display three RMS parameters
simultaneously, or one Energy Parameter. The displayed readings update every second.
• For each row: Kilo, Mega (Kilo + Mega = Giga) indicator and a Negative(-) indicator.
• Load bar graph gives the indication of consumption in terms of the %Aavg of load.
• Five keys to scroll through the display pages.
The EPM 2000 products solves the problem of cluttered indicators by prominently displaying the
parameter name right on the large, numeric readouts. For the first time in a Panel Meter, the
Parameter Name is as clearly readable as the value. The name is displayed every 9
th
second for
2seconds(8+2), as well as each time you press a key. This also allows programmable Phase
Labels in the EPM 2000 products. You can choose from 123 (Factory setting), Abc, ryb, pqr, or
rst.
At this point you can scroll to the next page you want to see. If you’re not sure which page
you’re watching, one press of any key will immediately identify the Name of the Parameter
being displayed. The second key press takes you to the next page.

1.2.1. The Indicators
Table 1-1-: Kilo, Mega and Negative Indicators
M
Mega: When lit, indicates that the reading is in Mega, (10^6). 10,000K is shown as
10.00M. 1.0 M is displayed as 1000K.
When Kilo and Mega are both glowing, the reading is in Giga (10^9). 10,000M is
shown as 10.00G. 1.0G is shown as 1000M.
Neg: -When lit, indicates that the reading is negative Per IEEE 100 and industry
standard practice by meter men, the following are Negative:
• With Forward Flow of Watts: Capacitive (Leading) VARs & PF.
• With Reverse Flow of Watts: Inductive (Lagging) VARs & PF and Watts.
K Kilo: When lit, indicates that the reading is in Kilo (10^3). 10,000 is shown as
10.00K. 1.0K is shown as 1000.
Table 1-3: Giga, Mega (M), Kilo (K) & Decimal Point Scaling
RMS Reading Indicator
Less than 0.001 K, M Off, displays “0.000”
Less then 9999 K, M indicators Off
Above 9999 K ON
Above 9999 k M ON
Above 9999 M Giga (K + M indicators ON)
Upto 9999G Giga
Above 9999G Display shows “Hi” for +ve numbers and “Lo” for –ve numbers
RMS readings are 4 digits. Energy readings have eight digits, including four additional fractional
digits. The maximum number the Meter handles is 9,999 G for RMS and Energy values.
This means that the Energy readings of the meter will overflow between approximately 2 months
to 3 years depending upon the PT and CT ratios programmed. See Table 2.6 “Integrator Overflow
Period”

GE Multilin Sub Meters
1.2.2. The Keys
Operating the meter is easy using the five keys to take navigate through the Keypad Operations
Table. The Display Pages “expand” as you go right, much like the directory or Explorer “tree”
displayed on any computer. The display shows where you’re headed.
Table 1-5: The Keys
Right Key:
• Go forward into sub-parameter pages.
• During Edit Setup values, select next (right side) digit.
Left Key:
• The Opposite of the Right key.
• Go Back towards the Main Parameter Pages. Going Left past “Prog” requires Code
entry to enter Main Menu (Setup and Clear)
• During Edit Setup, selects previous (left side) digit
• Exits from Edit mode, back to the Main Menu.
Up Key:
• Scroll Up thru other Display Pages at the same level.
• Continuous pressing for 3 seconds initiates limited Auto-scroll (within the same
group of pages). Press any key to return to Manual scrolling.
• Increases the value of the blinking digit during Edit. Typically while changing the
Meter Setup settings.
Down Key:
• The Opposite of the Up key.
• Scroll Down thru other Display Pages at the same level, thru all functions.
• Continuous pressing for 3 seconds initiates the Full Auto-scroll mode, thru all
functions. Press any key to return to Manual scrolling.
• Decreases the value of the blinking digit during Edit.
TURBO Key:
• The TURBO key scrolls thru the following pages: RMS (Home page),
VLL, A,PF VLN,A,F VA, W, VAR W,VAR, PF PF1, PF2,PF3 , VAh and
Wh. This gives simple one-touch access to the most commonly used parameters,
even for unskilled operators. “One Touch” does not operate in the Setup (Program)
Mode.
• If you’re lost, the TURBO key is a quick way to get back to the RMS home
page.
• Continuous pressing for 3 seconds initiates Auto-scrolling through the above
Favorite pages.
The parameter name is displayed every 9
th
second for 2seconds, as well as the first time you press
a key.
At this point you can scroll to the next page you want to see. If you’re not sure which page
you’re watching, one press of any key will immediately identify the Name. The second key
press takes you to the next page.
The Meter Menus and Displays are organized as below. Navigating with the EPM 2000 is very
easy and intuitive. For full details, see the Keypad Operations Table. The left-most column
(RUN, CLR, SET) constitutes the “Main Menu”. Press the key in the direction you want to go.
Display shows where you’re headed.

1.2.2.1. Keys Example
Here’s an example to try:
When you switch on a factory fresh meter, it starts at the “RMS” page, circled “1” in the
diagram below. This will be our “Home Page”.
From here, to now go to the VAh Energy Page, circled “3” in the diagram below:
1. Start at “RMS”
2. Go Down to “Integ” and
3. Go Right to “VAh”
There are no complicated key sequences, since the grouping of parameters is intuitive. And
the keys always do what they say, under all modes.
A complete Keypad Operations Map appears in the next chapter. “RUN” constitutes the
Main Menu, along with “Clear” and “Set”, not shown above, but evident in the left-most
“Main Menu” (“RUN”, “CLR”, “SET”) column. Getting into the Main Menu requires you to
first enter a code.

, A
oC
w.r.t. the corresponding Voltage Line-Neutral vector.
• Frequency:
Measured from whichever phase is active.
• Power: VA, W, VAR, PF. Per phase and Total. Per-Phase W readings provide a quick CT
Polarity Check. A negated W phase reading indicates CT reversal.
• Energy:
VAh, Wh, +VARh (Ind), -VARh (Cap), Run Hrs, On Hrs, Supply Interruptions (outages)
• % average Load Bar graph:
Load Bar graph indicates consumption in terms of %Aavg. Now user can quickly estimate the
load by viewing the display without operating any keys. The bar graphs consists of 12 segments.
Each segments indicates 10% of average load.
• Kilo, Mega, Giga indication for the above parameters.
2.1. Keypad Operation
The Table below is quite simple to use. Look at the shaded left half, under the parameter
“Name”: Follow these simple steps.
• First take a quick look at what the Keys do. Try the simple example.
• Now, try getting around to other parameters, by moving Up, Down, Right and Left. For
viewing readings in different display pages you will normally be within (to the right of)
the “RMS” and “INTG”.
o You cannot go Down or Up through the thick horizontal lines- you must navigate
Left, around them
o The “Kilo”, “Mega” and “Negative” Indicators are automatic. “Kilo” and “Mega”
light up together to show “Giga”.
• To go Left into the Main Menu (“RUN”) enter Code- See Table 2.1 Note 1
• Once in the Main Menu (“RUN”), you can go Down to “CLR” or “SET”. You can then
clear the integrator or Setup Meter Settings by going right. When done, go left back to the
Main menu, go Up to Run then go Right in to RMS to view the Display Pages again.

NOTES:
1. To “Clear” Integrated values or “Set” meter settings, you must first enter the Main Menu.
• Go Left to the “RUN” page from "PROG".
• You must now enter the Factory Set code of 1000, to proceed.
o "Code y”, followed by the entry of the Code “1000" is required.
o To enter the code, edit the blinking digit value Up or Down to get “1000”.
o Keep going Left.

2.1.1. Auto-Scroll
Auto-Scroll allows you to monitor a group of Display Pages sequentially, every 5 seconds,
without constant key pressing. This is convenient for viewing from a distance. Since the EPM
2000 displays the Parameter Name(1sec) followed by the Value(4 sec) on the same large
displays, both are equally readable from a distance. No more squinting at a clutter of
parameter indicators.
To enter auto-scroll, go to the desired display page and keep the Up or Downkey
pressed for minimum 3 seconds. The display flashes “Auto” and then automatically scrolls
through other pages at the same level (column in the above table). Press any key to revert to
Manual Scrolling.
• The Up key enters Limited Auto-scroll – within the same Group, eg only “RMS” or
only “INTEG”.
• The Down key enters Full Auto-scroll- down the entire column of pages.

RMS, VLL,A,PF VLN,A,F
VA,W,VAR W,VAR,PF PF1,PF2,PF3 VAh Wh
. This gives simple one-touch access to
the most commonly used parameters, even for unskilled operators. “One-touch” does not
operate in the Setup (Program) Mode. Optional parameters are in blue color.
• If you’re lost, the TURBO key is a quick way to get back to the RMS home page.
• Continuous pressing for 3 seconds initiates Auto-scrolling through the above Fav pages.

2.2. Setup (Program)
The Meter must be Set (programmed/configured) to match the application settings, before
use. Otherwise, the readings will be wrong. All the Setup values can be re-programmed at any
time, upon entering “SET” However, the settings: Sys (Star/wye or Delta), Vpri, Vsec, Apri,
Asec critically determine the scaling of measured readings. While the scaling may be used to
tune out Instrument Transformer errors, wrong settings will upset the readings of running
systems. It is the user’s responsibility to ensure that only qualified personnel correctly Set-up
the Meter.
