2.OVERVIEW
The EM 6400 DigitAN are digital power meters that 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 EM 6400 DigitAN 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. Other settings such as communication
parameters must also be programmed as needed.
CONZERV stands behind your EM 6400 DigitAN meter with complete User Support and
Service. If the need arises, please do not hesitate to contact us at [e-mail].

2.1.Physical Description
FRONT: The front panel has 3 rows of 4 digits / characters each, with auto scaling “K” kilo,
“M” Mega and “--” minus indications. The “kilo” and “Mega” indications lit together show
Giga readings. The Load bar graph to the right of the display gives the indication of
consumption in terms of the % A Load with respect to the FS selected. Five smart-keys make
navigating the parameters very quick and intuitive for viewing data and configuring (Setup)
the EM 6400.
REAR: The voltage and current terminals and the communication port are located on the
back of the meter. CAUTION: These contain hazardous voltages during operation and
must be operated only by qualified and authorized technicians.
2.2.Front Panel
The front panel contains the following indicators and controls:
•Three rows of alphanumeric 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, which gives a unique analog indication of % loading (% FS CT Pri).
•Five keys to scroll through the display page.
The EM 6400 solves the problem of tiny cluttered indicators by prominently displaying the
parameter name right on the large, alphanumeric readouts. For the first time in a panel meter,
the parameter name is as clearly readable as the value. The name will be displayed for 2
seconds as well as each time you press a key and then the Value for 8 seconds. This method
also allows programmable phase soft-Labels in the EM 6400 DigitAN meters. You can
choose from 123 (Factory setting), ABC, RYB, PQR or RST.

2.2.1.The Indicators
Table 2.1: Kilo, Mega and Negative Indicators
M
Mega: When lit, indicates that the reading is in Mega, (10^6). 10,000 K is shown
as 10.00 M. 1.0 M is displayed as 1000 K.
When Kilo and Mega are both glowing, the reading is in Giga (10^9). 10,000 M is
shown as 10.00 G. 1.0 G is shown as 1000 M.
-
Neg: -When lit, indicates that the reading is negative Per IEEE 100 and industry
standard practice by meter-men, the following are Negative:
•When the flow of watts is forward: Capacitive (Leading) VARs & PF are
negative.
•When the flow of watts is reverse: Inductive (Lagging) VARs & PF and Watts
are negative.
KKilo: When lit, indicates that the reading is in Kilo (10^3). 10,000 is displayed as
10.00 K. 1.0 K is shown as 1000.
Table 2.2: 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 OFF
Above 9999 K ON, M OFF
Above 9999 k M ON, K OFF
Above 9999 M Giga (K + M indicators ON)
Upto 9999G Giga
Above 9999G Display shows “Hi” for positive numbers, “Lo” for negative numbers
RMS readings are four 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 at 3 values of kWh or kVAh
(selectable through PROG menu - Setup) depending upon the PT and CT ratios programmed.
See Table 3.4 “Integrator Overflow Value”.
2.2.2.The Keys
Operating the meter is easy using the five smart keys to 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 2.3: The Key pad operation table
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 to the main parameter pages. Going left past “PROG”
requires code entry to enter PROG menu (Setup and Clear)
•During Edit Setup, selects previous (left side) digit
•Exits from Edit mode, back to the PROG menu - Setup.

Up Key:
•Scroll up through display pages at the same level, within the same
function.
•Continuous pressing for 3 seconds initiates limited auto-scroll (within the
same function). Press any key to return to manual scrolling.
•While editing, 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 through other display pages at the same level, through all
functions.
•Continuous pressing for 3 seconds initiates the full auto-scroll mode,
through all functions. Press any key to return to manual scrolling.
•While editing, decreases the value of the blinking digit during edit.
TURBO Key:
•The TURBO key scrolls through the following pages: RMS (home page),
VLL, A, PF VLN, A, F VA, W, VAR W, VAR, PF PF1, PF2, PF3,
V1,'2,'3 A1, A2, A3 VA.d, R.d, T.R, MD, HR VAh
Wh R.VAh R.Wh t.VAh t.Wh. . This gives simple one-touch access
to the most commonly used parameters, even for unskilled operators. “One
Touch” does not operate in the PROG menu – Setup.
Note EM6436, TURBO key scrolls through the following pages:
RMS (home page), VLL, A, PF VLN, A, F A, W, PF PF1, PF2, PF3
Wh and Run hours
EM 6433, TURBO key scrolls through the following pages:
RMS (home page), A, W Wh and Run hours
•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
TURBO pages.
•During the power up, if the TURBO key is pressed, meter will go in to
PROG menu - Setup. This is the simplest way to enter in to the setup.
The parameter name is displayed every 8th second for 2 seconds, as well as the first time you
press a key. At this point press the next key immediately to scroll to the next page you
want to see. If you are not sure which page you’re watching, one press of any key will
immediately identify the name. Pressing the key again immediately takes you to the next
page.
The meter menus and displays are organized as below. Navigating with the EM 6400 is very
easy and intuitive. For full details, see the Keypad Operations Table and the Meter Function
Map. The left-most column (RUN, CLR, SET) constitutes the “PROG menu”. Press the key
in the direction you want to go. Display shows where you’re headed.
Press the key that takes you in the desired direction.
