INTRODUCTION
The ELITEpro XC is a powerful and versatile tool for pinpointing electric usage and quantifying energy
usage. It is capable of measuring, storing, and analyzing consumption data including Volts, Amps, Watts,
Volt-Amps (VA), Volt-Amps reactive (VAR), Kilowatts (kW), Kilowatt Hours (kWh), KVAh, kVARh, and
Power Factor (Pf) of an electrical load or an entire building. Analog input channels are especially helpful
when used in conjunction with power measurements to correlate the consumption of electricity with
environmental, HVAC plant performance or other process conditions. The ELITEpro XC also offers some
power quality features such as the ability to view in real-time voltage, current, and power waveforms
and calculate harmonics to the 63
The ELITEpro XC is line-powered from the service being measured, eliminating the need for external
power or space-consuming batteries at the job site. The measurements are stored in on-board,
non-volatile memory in a time series format at an interval selected by the user. The ELITEpro XC can be
mounted anywhere with its magnetic back and is small enough to be secured inside the electrical panel.
The Windows-based ELOG software package is used to set up the meter, display metered values, and
retrieve and analyze the collected data. ELOG graphically displays recorded data, performs analysis and
facilitates automatic remote data collection. Data is also easily exported to popular spreadsheet and
database programs for additional analysis.

DC VOLTAGES
The meter is designed to measure AC voltages for installations up to 600 VAC. The
meter is also capable of measuring DC voltages up to 600 VDC with the following
caveats.
1) The internal fuse installed in the meter is not a suitable disconnect for voltages
above 80 VDC. Customers using the meter for high voltage DC systems must install
a UL listed inline 600 volt DC fuse with a rating of 1 amp or less. These fuses are
commonly available in the solar power market.
2) UL testing of the meter was conducted on AC systems only. DC results are
comparable but not tested.
3) DENT Instruments ELOG software does not currently have a configuration that is
specific to DC systems. Values reported for voltage, current, KW, KWH will be
correct however it should be noted that the meter will also report values that

1) Mount the ELITEpro XC using the black tab on the end of the case containing the PhaseChek and
voltage lead connections. Use a screw to securely mount the ELITEpro XC near a dedicated circuit
disconnect breaker.
NOTE: Allow adequate space for accessing all ports and connectors. The mounting tab is intended for
short term metering (less than 6 months) and must be subject to monthly monitoring by qualified
personnel to verify the ELITEpro XC or its wiring have not shifted.
To remove the logger, remove the screw and roll the magnets off the cabinet it is mounted to.
NOTE: For temporary, spot load monitoring, the four magnets on the back of the ELITEpro XC case can
be utilized to hold the logger on unpainted metal. The maximum combined weight of the logger and any
attachments the magnets can support with a 4 times safety margin is 18oz (500 gm). The logger must be
attended by the electrician when it is temporarily mounted by the four magnets.
In order to prevent injury upon removal, it is recommended practice to roll the device off, due to the
strength of the magnets.
2) Mark the dedicated circuit as the disconnect for the ELITEpro XC.

ELITEPRO XC CONNECTIONS
The ELITEpro XC has the following connections:
Four current transformers (CTs).
Four voltage wire leads for connecting to voltage sources (L1, L2, L3, and Neutral).
Four analog input channels can be individually used to record process or environmental correlation
studies with power.
Power In/Out for connecting a DENT-provided external power supply or for powering external
devices. Maintain polarity as marked on the case:
In: 6-10 Vdc, maximum input of 500 mA
Out: 6 Vdc output, up to 200 mA for powering other external devices
USB connector for high speed downloads, setup, and communication with a computer. The ELITEpro
XC is also powered from the USB connection. If a USB cable is to be used inside an electrical panel, it
must be rated to the appropriate voltage or wrapped in an appropriately rated insulating sleeve. The
DENT-supplied cable does not meet this requirement without an insulating sleeve.

CT CONNECTIONS
NOTE: Use only inherently safe 333mV output CTs supplied by DENT. Never use current output CTs. The
UL listing covers the use of the following DENT Instruments CTs that are UL Recognized and have been
evaluated to IEC 61010-1:
CT-HSC-020-X (20A Mini), CT-HSC-050-X (50A Mini), CT-HMC-0100-X (100A Midi), and the CT-HMC-0200X (200A Midi). The use of any other CT will invalidate the UL Listing of the ELITEpro XC.
1) Connect the CTs to the channel(s) on the ELITEpro XC labeled CH 1, CH 2, CH 3 and CH 4. The CT
leads need to be connected to the terminal block using a small screwdriver. For RōCoils, also
connect the shield (bare) wires to the right-most ground terminal marked “S” (shield).
2) Place the CTs on the phase wires of the load to be monitored and corresponding to the phase of the
voltage loads. The CTs must be placed as follows for each channel:
Left connector pin is the positive or high-side wire
Right pin is the negative or low-side
When using DENT Instruments current transformers, connect them as follows:
Split-core CTs (removable leg)—the white CT wire is (+) and the black wire is (-).
Clamp-on CTs (clothes-pin type)—the red wire is positive (+) and the black wire is negative (-).
RōCoil CTs (flexible, Rogowski-style)—the white CT wire is (+) and the brown wire is (-).
If you are using RōCoil CTs, be sure to connect the bare wire to the “S” (shield) screw terminal. This
reduces interference and improves the accuracy of the CT.
22

Connecting Split-Core Style Millivolt CTs to a Load
1) Open the CT by holding on to the removable leg and pulling it apart.
2) Connect CT around the load conductor to be measured. Make sure the maximum current of the
conductor does not exceed the maximum CT rating listed on the CT data sheet.
3) Carefully re-connect the removable leg while ensuring the CT core alignment matches. The

ANALOG CHANNEL CONNECTIONS
Analog inputs are especially helpful when used in conjunction with power measurements to correlate
the consumption of electricity with environmental, HVAC plant performance or other process
conditions. Typical uses might include logging ambient temperature, building temperatures, solar
insolation, tank pressures, duct flows, etc.
The ELITEpro XC has four analog input channels that can be configured for voltage or current input used
in any combination among channels. The limiting specifications for analog input are shown below.

The following sensor types are supported and selected through the ELOG 15 software interface.
0/4–20 mA externally powered current loop
0–30* VDC single ended, non-isolated
NOTE: The ELITEpro XC can measure input voltages up to 30.0 volts. The polarity protection circuitry
however can only withstand 15 volts of reverse-applied polarity without permanent damage to the
meter. The maximum allowable current flowing into the analog input terminal is 23 mA.
CAUTION: Ensure that the sensor current/voltage is within range and the channel is correctly
configured using ELOG 15 before connecting external sensors. Sustained exposure to elevated
signals may damage the ELITEpro XC and this will void your warranty.
CAUTION: Observe the correct signal polarity when connecting voltage sensors to the ELITEpro XC
above 10 volts. Damaging currents may flow from the connected sensor in the event of reverse
polarity or misconfiguration and this will void your warranty.
Channel types (voltage or current) should be configured using the ELOG software prior to connecting
external sensors. This sequence will prevent the unexpected/unpredictable combinations of voltage
transducers connected to low impedance loads (499 ohm) or current transducers with an open circuit.
The first set of Sensor and Output fields on the screen represent the Physical Range. This is where the
user enters the low and high process values from the sensor. This data can typically be found on the
data plate or data sheet of the sensor (typical sensor image below). The second set of Sensor and
Output fields represent the Electrical Output. This is where the user enters the minimum and maximum
electrical output values of the sensor, also listed on the data plate or data sheet.

Current Loop Connection
Sensors using current loops are widely used in industry to communicate analog signals in the presence
of electromagnetic interference. Both 2- and 3-wire current loops (often referred to as loop powered or
separately excited, respectively) are commonly used in industry. Both types of current sensors are
illustrated in this section. Internally, the ELITEpro XC uses 0.1% precision 499 ohm resistors to measure
the voltage drop impressed by the external current source. Current loop sensors will typically be
powered from a 24-volt DC supply. The ELITEpro XC has four measurement channels. The negative
terminals of each channel are common to each other and connected to the reference plane for power
measurements. For this reason it is imperative that the ELITEpro XC be connected as the last component
in the current loop rather than the first if multiple channels are used. Best practices are to use a single
power supply for all sensors to reduce the occurrence of ground loop current between supplies.

Voltage Connection
Voltage output sensors and 3-wire current loops will typically use one voltage for powering the sensor
and a second voltage (or current) for sending an output signal. Sometimes the power supply ground and
signal reference conductor is shared between two circuits resulting in a three wire device. This economy
usually comes at the installer’s expense of having to form a junction at the power supply, sensor, or
meter. Sensors having four terminals are also popular and are simply connected to the meter by
observing the indicated polarity between sensor and meter.
Separately Excited Current or Voltage Loop Configuration

Page 30
POWER IN/OUT CONNECTION
The Power In/Out connection can be used with the ELITEpro XC to measure loads where the line voltage
is less than 80 VAC and the internal power supply will not operate (a small battery bank, for example) or
where AC line voltages are not available and you want to use current transformers to record amps only.
It can also be used as a 6V output to power any outside devices.
To power the ELITEpro XC using an external supply contact DENT Instruments for an
appropriately-rated power supply.
The ELITEpro XC can also supply 6V DC at up to 200mA to an external device when the ELITEpro XC
voltage leads are connected to mains power between 80 and 600 VAC.
DIGITAL CHANNEL CONNECTIONS
Digital channel connections are part of legacy products produced before ELITEpro XC, such as the
ELITEpro SP. Users of ELOG 15 connected to legacy products will see digital channels instead of analog
channels on the screen. The Digital channels provide users with a way to export kWh, kVAh, and kVARh
pulses to external devices. The ports are grounded when closed, and floating when open. For example, if
the setup table Digital 1 is configured to output KWh pulses with a Scale of 1.0, Digital channel 1 will
output a pulse for each kilowatt-hour of energy measured by the meter on Power Channel 1.
In Digital 2 the Scale is set to .001 (kWh), so a pulse would be generated for each Watt-hour of energy
measured on Power Channel 2. See below.
For example, in the Digital Channels setup below: A desk lamp with a 100W bulb will use 0.1 kWh every
hour; the meter produces a pulse once every 10 hours on Power Channel 1 and 100 pulses every hour
on Power Channel 2. In contrast, a 1,000W heater will use 1 kWh every hour; the meter produces a
single pulse once an hour on Power Channel 1 and 1,000 pulses every hour on Power Channel 2.
Digital 1/2: Turns the channels on/off by choosing an option from the drop-down list.
30
Page 31
1) Enter a descriptive name in the Name field to identify your logger (optional).
2) Choose which Power Channel (CT) will be used to generate pulses from the drop-down list.
NOTE: The Power Channel drop-down list displays any enabled channel, allowing users to choose which
one(s) to use as a source for the pulses.
For example, if the setup table is only configured to measure one power channel, no other options will
be available in the Power Channel drop-down list. If the setup table is configured to measure two power
channels, you may choose either “1” or “2” from the drop-down list.
Users may wish to measure different pulse output variables on each channel. The Power Channels for
Digital 1 and Digital 2 may both be set to “1,” or set to “1” and “2” in order to measure the pulse outputs
of two Physical Power Channels, or both may be set to “2.” This enables users to measure pulse outputs
with different data in the Value and Scale described in the following sections.
3) Select a parameter (kWh, kVARh, or kVAh) to be used as the source for pulses from the Value
drop-down list.
The ELITEpro SP is capable of measuring the pulse output for KWh, KVAh, or KVARh. Only one may be
measured at a time if a single digital output channel is turned on, but users have the option of
measuring two different values concurrently from the same Power Channel if both Digital 1 and Digital 2
are in use.
4) Enter a scale in the Scale field to assign a significance to the pulses.
For example, if 22 is entered in the Scale field and kWh is selected for the Value, then each pulse
generated by the meter is equal to 22 kWh on the selected Power Channel.
NOTE: The maximum output rate is five (5) pulses per second, or 5Hz, with a maximum current of 75mA
and 30V DC.
31
Page 32
To measure outputs pulse:
1) To count pulses, connect the wires of your measurement device to the +/- connection points on the
ELITEpro SP.
NOTE: You can open ELOG 15, and ensure that your PC and logger time are synchronized by selecting
Logger > Logger Clock > Synchronize Time to Match PC.
2) Using an existing setup table (or follow the steps in Section 2 of this manual to create a new one),
turn on the Digital 1 and/or Digital 2 channels.
3) Enter a descriptive identifier in the Name field. Choose your Power Channel to measure, the desired
option from the Value drop-down list, and enter a scaling factor in the Scale field.
4) Click SEND SETUP TABLE to Logger.
NOTE: When logging is turned on or a new setup table is sent, pulse outputs start at the integration
period relative to the hour that logging starts. For example, if you have a 5 minute integration period
and you turn logging on at 1:05:01 PM (5 minutes and 1 second after the hour), logging AND pulse
output accumulation will NOT start until 1:10:00 PM.
5) Upon completion of your pulse output measurements, disconnect the wires of your device.

SECTION II: BEST PRACTICES
Creating and Using the Logger Setup Tables
The ELITEpro XC requires that it be configured for use by first creating a “Setup Table” file and then
loading the file into the meter. The ELITEpro XC is a flexible meter that can monitor a wide variety of
parameters over a wide range of currents, voltages and service types. This requires that you determine
what is recorded and at what intervals.
Setup Tables are created using the ELOG software and saved to the computer with a .sut file extension
appended to the name. A .sut file may be:
Loaded into the ELITEpro XC immediately or at a later time but prior to beginning a monitoring
session
Sent to any number of loggers
Retrieved from an ELITEpro XC, modified and saved, and resent to the logger
CREATE A NEW SETUP TABLE
A new setup table can be created for any of the devices compatible with the current version of ELOG 15.
This includes a variety of DENT Instruments legacy products in addition to the ELITEpro XC.
If the logger is not connected and communicating with the computer, setup tables can still be created
and saved to the computer.
1) Select File > New > Setup Table File and click OK.
If your computer is currently communicating to an ELITEpro XC, the ELOG software assumes the new
setup file is for the connected device. Selecting New displays a setup table with the default parameters.

The ELITEpro XC has four configurable hardware channels corresponding to the current transformers or
other sensors.
1) Click on the maximize button in the upper right-hand corner of the Setup Table window to display as
much of the full screen as possible.
2) Click on the down arrow next to each channel you
want to configure.
CT 1 must be placed on the phase listed as V High for
Channel 1 in the ELOG setup table. CT2, CT3 and CT4
must also correspond to the appropriate phase as
shown in Channels 2, 3, and 4 in the ELOG setup table.
3) Select Power to turn on any channel. These channels
refer to the current transformer inputs from the ELITEpro XC. Selecting Power displays the options
for configuring the channel.
4) Enter a name for the channel, then select the Voltage References, Current Transformers, and any
Recorded Values.
NOTE: The PT Ratio is used when monitoring voltages greater than 600 VAC (maximum rating of the
ELITEpro XC). Use an instrument grade transformer with low phase shift and high accuracy since errors
in the transformer will translate directly into errors in the recorded data. The PT Ratio value put into the
Setup Table in the logger should be the transformer primary:secondary ratio. This feature is useful when
monitoring high voltage loads such as found at a substation or on transmission lines.
For example, a potential transformer is used to monitor a 4160 VAC load. The transformer steps the
voltage down from 4160 to 120 VAC. The PT equals the transformer ratio or 4160/120 = 34.667. Thus,
34.667 would be used for the PT value in the channel Setup Table.

CALCULATED POWER CHANNELS
Channels 5 and 6 are the Calculated Power Channels. They combine the data from two or more power
channels (also called "hardware” or “physical channels") and are used primarily for calculating total
system volts, amps, kW, kVA, power factor, and kVAR in polyphase or multiple single phase systems.
The Calculated Power Channels are frequently used to:
Record total system power parameters on
three phase loads.
Optimize the logger’s memory by collecting
and combining data from two or more
channels instead of collecting data from two
(or more) separate channels.
For a description of the formulas used to
compute channels 5 & 6 based on the CT input
channels 1–4, see Appendix E—Calculated
Power Channel Formulas.
ID YOU KNOW
Channels displays:
None—If only one power channel is turned on in a
Setup Table, then channels 5 and 6 do not appear.
Channel 5—If two power channels are turned on,
then only channel 5 appears.
Channels 5 and 6—If three or four power channels
are turned on, then channels 5 and 6 appear.
By default, the Calculated Power Channels are set to
“Off” when they initially display in the Setup Table
window.
Combining Channels
To combine channels and maximize memory use:
1) Depending on your setup table configuration, ensure that the Physical Power Channels you wish to
combine are set to Power.
It is recommended that the Recorded Values flags of Volts, Amps, kW, kVA, PF, and kVAR for the
individual channels be left on. However, if maximum use of the memory is required they can be
turned off.
Default recording flags may have the Average checkbox selected in each drop-down menu for the
Recorded Values.
2) Under Calculated Power Channels, turn on the channel by selecting Power Sum from the Channel 5
menu. Perform the same function for Channel 6, if desired.
3) Enter a name for the Calculated Power Channels (optional).
4) Select the Physical Power Channels to be added together in the Combine Channels box.
5) Set each recording flag for Volts, Amps, kW, kVA, PF, and kVAR as desired.

3) Enter the raw sensor output minimum/maximum values. This data is typically found on the data
plate or data sheet of the sensor. Typical values for voltage devices are 0-5, 1-5, 0-10, 0-15, 0-30 for
voltage devices and 0–20, 4-20 for current loop devices.
4) Enter the corresponding engineering value to the sensor range (i.e., psig), the units, and the
average, minimum, and/or maximum record.
5) Click Send Setup Table to Logger to load the configuration into the data logger.
Best practices are to confirm the operation of all sensors. Use Logger > Display Real Time Values > Show
as Text or click the Display Real Time Text Values speed button before commissioning the logger for
prolonged data logging projects.
DID YOU KNOW? To trouble shoot or calibrate a
current or voltage sensor it is convenient to set
the physical range fields to be equal to the
electrical output values. The Real Time Values
readings can then be compared directly with
voltage or current measurements taken from a
DVM. Offset or gain errors can be corrected by
adjusting the min value or span (max–min).

ID YOU KNOW
PHASECHEK™ LEDS
PhaseChek is a unique feature of the ELITEpro XC that
simplifies installation by ensuring proper CT-to-voltage
phase installation and avoiding faulty data collection.
The ELITEpro XC has four tri-color PhaseChek LEDs, one
green/red/blue LED for each CT input. These LEDs provide
the following information:
All LEDs are green—the system power factor is greater
than 0.55 and the CTs are properly placed on the corresponding voltage phases and the CT is
oriented properly (arrow toward the load).
LED is red—there is a CT voltage phase placement error. (Or the Power Factor is less than 0.55.)
LED is blue—the CT is on backward (-kW) with the arrow pointed away from the load
power factor is less than 0.55, the
LEDs will be red even if connected
properly. This situation is rare but
could occur if, for example, the load
to be monitored is a lightly loaded
electric motor. It is common for an
individual phase power factor to be
less than 0.55 and the corresponding
LED will be red.
LED flashes red and blue—CT is on backwards and on the wrong voltage phase
NOTE: If the Physical Power Channel (CT) is turned off in the setup table, the corresponding PhaseChek™
will be dark.
COMM—COMMUNICATIONS LED
The ELITEpro XC COMM LED flashes different colors (green, blue, red) to indicate that the logger is
connected, logging information, and communicating with the computer. Which color indicating which
condition is dependent on the version of firmware being used by the logger. However; one color always
indicates the same condition: green will flash approximately once per second when the ELITEpro XC is
logging and communicating with the computer.

CURRENT TRANSFORMER (CT) SELECTION
NOTE: The UL listing covers the use of the following DENT Instruments CTs that are UL Recognized and
have been evaluated to IEC 61010-1:
CT-HSC-020-X (20A Mini), CT-HSC-050-X (50A Mini), CT-HMC-0100-X (100A Midi), and the CT-HMC-0200X (200A Midi). Though all other CTs provided by DENT Instruments have been tested and certified to the
same IEC 61010-1 standard by other Nationally Recognized Testing Laboratories (NRTLs), the use of any
other CT will invalidate the UL Listing of the ELITEpro XC. This is simply a decision made by UL, and in the
opinion of DENT Instruments, all CTs provided are equally safe to use.
Proper CT selection is critical for accurate results. Use CTs with the smallest diameter to fit around the
wire(s), and whose rated amperage is not less than 100% of the largest load expected.
Generally, best CT accuracy will result when the load operates as close to the full rating of the CT as
possible. Do not use CTs whose maximum current rating greatly exceeds the maximum current of the
load of the item being monitored.
The following table contains a list of some of the DENT Instruments CTs.

AutoPoll
AutoPoll is a standalone Windows program (supplied with ELOG) that may be used for
unattended and automatic data retrieval from a number of remote loggers where the PC
connects to the loggers. A complete description of AutoPoll can be found in Appendix D—
AUTOPOLL: Unattended Data Collection.

Retrieve Data From Logger
Retrieves data from the logger and saves it as an .elog file on the hard disk. The Select A Directory And A
Name… dialog box displays prompting you for a file name. The default name is the logger serial number
plus two digits that correspond to the number of times that data has been retrieved from the logger,
however, at this point you may name the data file whatever you wish.
There are two checkboxes in the lower left of the dialog box to select if you want to add (append) the
data to an existing file and/or create an ASCII file of the data.
When a logger’s memory is downloaded, the data may be added or “appended” to an already existing
file from the same logger. Check the Append New Data To Existing Data File box. The name of the
dialog box changes to Select a Data File to Append Data To. Select the file to which you wish to add the
data.
72
Page 73
The selected file must have used the same Setup Table of the earlier downloaded data. Selecting a file
with different Setup Table parameters than those in the logger causes the following warning to display:
When the data is retrieved, a second comma separated value format (.csv) file can be created at the
same time as the .elog data file is being downloaded. A .csv file is also called a “flat file,” or “ASCII file”
and can be opened in other applications such as spreadsheets and databases.
The data is saved to the folder specified in Tools > PC Setup > Data Files Saved To: unless changed in the
Select a Directory and A Name… window. The default data folder is
C:\Users\UserName\Documents\DENT\ELOG\Data.
To view a data file, use Data > Open Data File and then select the desired file.
Even if not downloaded as a .csv file, the original binary .elog data files may at any time be exported to a
comma delimited ASCII file with a .csv extension. See the Export Data File section to export a data file.

Display Real-Time Values Sub-Menu
The Display Real Time Values option shows instantaneous readings for channels in use in either a textual
or graphical format. Real-Time Values are an excellent way to verify the correct installation of a meter.
Real-Time Values may be displayed in either a textual or graphical format.
Show As Text
When this option is selected, a screen similar to the one on the following page displays. All channels
that are turned on (even if not being recorded) are displayed simultaneously. If a parameter is being
recorded by the logger, it will be shaded in green as shown in the Real-Time Channel Values window
(see next page). For a Power Channel, all six power parameters (V, A, kW, kVA, PF, and kVAR) are
displayed even if only one of the parameters is recorded.
This feature is useful for verifying correct installation of the logger.
This screen provides information about:
The real-time data (which can be paused for cross-channel comparisons)
The Line Frequency as measured between L1 and L2
How much memory has been used and how many days the memory has remaining before filling
The logger clock’s current date and time
Whether or not the data logging is turned on
Type of memory: Linear (Stop When Full) or Ring (Continuous)

Show As Graphs
This menu selection displays the data as a graph instead of the text format described previously.
Select Logger > Display Real-Time Values > Show as Graphs to display the following dialog box.
1) Select any or all physical power channels currently turned on in the logger in the Hardware
Channels To Display section.
-orSelect one or both calculated power channels currently turned on in the logger in the Summing
Channels To Display section.
Selecting a power channel activates the Parameters To Display option. You can only select one variable
at a time to graph. This is not like a text display option where parameters are viewed simultaneously.
This is due to differences in scaling and to reduce clutter on the graph. For example, you could display
kW from four channels simultaneously but not a kW and a KVAR even if it is from the same channel.
2) Select a parameter to chart.
3) Select OK to view the graph.
75
Page 76
The graph presentation is very similar to paper strip chart recorders. The graph begins on the left
edge and moves to the right. When it reaches the right edge, the entire graph scrolls to the left with
each new reading. This always displays the most current data values and the older points slide off
the left edge.
Use Set X and Y Axis to set the scaling and the line type (e.g., linear or logarithmic). You can also set
the amount of time data is graphed. This can vary from 1 second to more than 18 hours (65,000
seconds). Note that the X-axis scaling is only approximate.

Use Export Graph to save the graph in a graphical or textual format. Graphs can be saved in an .emf,
.wmf, .bmp, .jpg (default), .png format or as ASCII text file. You can select where the graph goes
(clipboard, file, or printer) and what measurements (pixels, millimeters, inches, points) are used to
save the graph.
Waveform Capture
Select Logger > Display Real-Time Values > Waveform Capture to view the actual current, voltage
and power waveform. The first capture is by default channel 1, but you can select different channels

DC are shown.
The actual value of the voltage and current for each harmonic may be found in the Harmonic Values
section. By clicking on the arrow buttons, higher and lower order harmonics may be selected.
Though only the first 31 harmonics are displayed in the graph, the Harmonic Values function can be
used to view the values up to the 63 harmonics. The Waveform Values section provides summary
statistics for the overall voltage and current waveforms. This includes the RMS value, THD, Peak
values, Crest Factor, Line Frequency, and K-Factor.

The image in the upper section of the Harmonic Analysis window is a single waveform snapshot. The
first image is by default channel 1, but you can select different channels and update the image, copy
the image to the clipboard for pasting into other programs, or print the image.
You can also record the harmonic values to your PC and then view a log of the harmonics in a
spreadsheet. When you click Record to PC the Harmonic Logging Parameters dialog box displays.
1) Select the Waveform Summary Data check box to create a “single column” of data in a spreadsheet
stored on the PC. The data is the average harmonic content for each harmonic of the first 31
harmonics over the period of time the harmonic data is collected.
Selecting Raw Harmonic Data creates a spreadsheet with the information above and a “row” of
the 31 harmonics for each update of the logger. Since the logger updates faster than one time
per second, selecting this option will create a LOT of data quickly!
2) Click OK and the recording begins.
The Record to PC button now reads Stop Recording on the Harmonics Analysis screen. Click that
button to stop recording harmonic values to the PC.
3) Click View PC Log to open a file of recorded harmonic values in a spreadsheet on your computer.
Realtime Peak Demand
When a logger is connected with Power 5 and/or Power 6 Channels on, select Logger > Display RealTime Values > Realtime Peak Demand to request a report showing peak demand and totalizer
values directly from the logger instead of from a data file.

Retrieve Logger Setup Table
This function instantly retrieves the Setup Table in the logger so it can be viewed, edited, resent to the
logger, or saved to the hard disk.
Logger Clock Sub-Menu
This function is used to set the logger’s internal clock time and date. You may change the clock manually
or synchronize it to the computer's clock. Note that the logger clock is actually set to UTC (also known as
Greenwich Mean Time). When reading the logger clock or viewing data files, ELOG reads the Windows
settings and converts the UTC time stamps in the logger to the local time zone of PC. If two PCs in
different time zones open a data file or read the logger clock they will see different times.
Set the logger’s internal clock and date using the following menu option: Logger > Logger Clock. You
may change the clock manually or synchronize it to the computer's clock.
Manually Set Logger Time
Use this option to manually set the date and internal clock. The date format defaults to what is used
by the time settings on your PC (mm/dd/yy or dd/mm/yy) and the clock uses a 24-hour format.
Synchronize Time To Match PC
Use this option to read the computer clock and automatically update the logger.

TOOLS MENU
The Tools Menu accesses the same PC Setup option available on the Communication sub-menu and also
includes options to install logger firmware or restore hidden messages.
PC Setup
Selecting Tools > PC Setup allows you to configure the computer connected to the ELITEpro XC. It is also
where you set the default file storage folders.
The Data Files Saved To: field displays the folder selected for storage. Click Browse to set the default
folder in which data files are saved. Data files are sent to the specified folder when retrieving data files
using the Logger > Retrieve Data option.
The Setup Files Saved To: sets the default folder in which Setup Tables are saved. ELOG will look in this
folder first when opening a Setup Table file.
The Logger Files Saved To: sets the default folder in which logger files are saved. ELOG looks in this
folder first for the Logger Lists to call when using the AutoPoll automatic data collection application.

The Direct Connect section displays the selected USB port and selects the computer’s USB port to which
the ELITEpro XC is connected.
ELOG 15 is equipped with a feature called Friendly Ports™. ELOG displays available Windows COM ports
with easy-to-understand device descriptions enabling you to find the appropriate port quickly and easily.
The Port Preferences option is used to hide COM Ports from ELOG, to change the order of COM Ports as
they appear in the dropdown control, and how they are searched when ELOG can't connect to a logger
on the desired port.
Ports that are unchecked will be hidden from ELOG. Ports are listed and searched in the order shown.
The order can be changed by selecting a port and moving it up or down.
Every time ELOG connects to a logger, its port is moved to the top of this list.
The Use Legacy Logger interface checkbox defaults to unchecked, and the ELOG software will only
display features and menu items relevant to the current software and hardware release. Select the
checkbox and click Save Changes to enable legacy menu items for customers using older legacy products
(ELITEpro).
The Enable Auto Launch of ELOG checkbox defaults to enable the Auto Launcher, which launches ELOG
(if not already open) when an ELITEpro SP or ELITEpro XC or newer ELITEpro is connected to a USB port.
When not checked, it disables the feature and hides the Auto Launcher icon in the system tray.
Connecting a compatible logger to a USB port while ELOG is already running will still result in ELOG
connecting to it automatically (if not already connected to another logger).
Update Logger Firmware (ELITEpro XC only)
If you receive a message when attempting to communicate between the ELOG software and the logger
stating, “The connected logger has firmware that is older than this version of ELOG supports, and may
not operate properly with this version of ELOG” refer to Appendix A to update the ELITEpro XC
firmware.

Graph Options
The Graph Options dialog box allows you to set several defaults when a new graph is created.
Select the Show graph data cursor check box to turn on the data cursor. The data cursor is a vertical
line that appears on a graph and is used to help visually line up multiple graphs. It can also be turned
on and off at any time while viewing a graph by right-clicking the mouse button.
If there is more than one variable plotted, all values are shown on the screen. The values are not
labeled but are shown in the same order that the variables appear in on the graph.
The data cursor may be moved by using the left-right arrow keys or by using the mouse to left click
on the cursor and drag it to the desired location.
NOTE: You will not see the cursor move when using the mouse until releasing the left mouse button.
Select the Show graph data points checkbox to display the specific point at which the data was
collected on the graph. It directly correlates to the Data Interval timeframe that was selected in the
Setup Table File, e.g. 15 seconds, 5 minutes, 1 hour, etc.
Select the Show analysis values checkbox to display the average, maximum, and minimum value for
each parameter plotted on a graph. The values appear to the right of the graph where the graph
labels are also shown. If desired, by unchecking the Show analysis values box, the values will not be
shown (or printed) on the graph.
At the creation of a graph you have the option of using the default graph attributes or the changes
that were last made. Select the Use default graph attributes or the Use last-saved attributes to
determine the attributes. The graph attributes include font sizes, background colors, graph colors
and numerous others and can be changed on the graph itself by right-clicking. Every time a graph is
made and there is a change to any of the attributes the changes are remembered by ELOG. Once a
graph is made you cannot change the graph attributes using this window. You must change them
from the graph itself.

Use the Graph Annotation field to tile the graph. If you make a lot of graphs and want to have the
same annotation on the graph, you may use this feature to add a description to the graph. Common
uses are the name of the consulting company performing the metering and analysis or the name of
the client.

Configure the Setup Table as follows:
2–½ ELEMENT METERS
*The CT on channel three of the ELITEpro XC is placed on the L2 phase and is backwards. Note that the
Ch3 CT is jumpered in parallel into Ch4 of the logger.
**Since the 2 ½ Element method is often used on high voltage metering, a PT ratio other than one is
typical and should be set to whatever the actual PT ratio is.
98
Page 99
***Set the CT value that is true for the CT connected to the ELITEpro XC. Again, because the 2 ½
element method is most often used in high voltage applications, there will be high voltage CTs present.
Use the high-accuracy 5A CT from DENT Instruments on the existing high voltage CT secondary. The CT
value used in the Setup Table should be the primary rating of the high voltage CT (assuming the
secondary output is 5A).
USING THE 2-WATT ELEMENT (2 CT) METHOD ON A 3-WIRE DELTA SERVICE
Blondel’s Theorem states that the number of watt elements (CTs) needed to monitor a system is one
less than the number of wires in the system. This means that a 3-Wire Delta service, even though three
phase, requires only two CTs to meter it as there are only three current carrying conductors. The
ELITEpro XC uses the 3 CT method for monitoring Delta services as a default because the data is easier
to interpret. However, if it is required to use only 2 CTs on a Delta such as when it is desirable to use one
ELITEpro XC to monitor two Delta connect loads simultaneously (such as two motors), connect the
meter as shown below.
2 CT, 3-Wire Delta
99
Page 100
Configure the Setup Table as follows:
USING THE 3-WATT ELEMENT (3 CT) METHOD ON A 3-WIRE DELTA SERVICE
Using the two watt element method on 3-phase 3-wire Delta services is a perfectly valid measurement
technique. The 2-element method also uses less logger memory and hardware channels and allows
measuring two Delta (3-wire) loads simultaneously. However, we recommend using the 3-watt element
method because the 3-element method is more intuitive. By placing a CT on each phase wire, it is easier
to understand what is happening in each phase without referring to phasor diagrams.
In 2-element measurements, System VA is calculated from Watts and VARs using the power triangle. In
3-element measurements, System VA is calculated as the sum of the VAs from the individual phases.
Both methods are completely valid.
The major difference is how harmonics are treated. When harmonics exist, they are usually only (or
mostly) present in the current and not in the voltage. Because watts and VARs are calculated as the
instantaneous product of volts and amps and because an existing third or fifth harmonic current does
not have a corresponding voltage harmonic, then the harmonics’ products are zero. Therefore, the
instantaneous product of volts and amps used to obtain watts and VARs does not include any harmonic
component. Thus, the 2-element method does not include any harmonic content in the calculation of
System VA. In 3-element systems, because System VA is calculated as the sum of the phase VAs, which
in turn are the product of the RMS volts multiplied by the RMS amps, then harmonics are included (in
the RMS amps).
There are two methods to calculate Power Factor. One is Apparent Power Factor PF=W/VA where VA=
Volts X Amps and VA would contain harmonic content. The other is Displacement Power Factor that
uses the Power triangle PF=W/SQRT (W^2 + VAR^2) which does not contain harmonic content. The
ELITEpro XC displays and records displacement Power Factor.
