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 mounting feet 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.

Quick Start to Using the ELITEpro

Mount the ELITEpro XC

The ELITEpro XC must be installed in an approved electrical panel or enclosure, following proper
installation practices according to the local electrical codes.

WARNING! Remove the LOGGER from all sources of voltage before mounting.

AVERTISSEMENT! ENLEVEZ L'ENREGISTREUR DE TOUTES LES SOURCES DE TENSION AVANT DE
MONTER.

1) Mount the ELITEpro XC using the black tab on the end of the case. 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 to which it is mounted. In
order to prevent injury upon removal, it is recommended practice to roll the device off, due to the
strength of the magnets.

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.

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), CT-HMC-0200-X (200A
Midi), and CTs that are UL listed to UL2808. The use of any other CT will invalidate the UL Listing of the
ELITEpro XC.

1) C

onnect 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.

DENT Instruments

Quick Start to Using the ELITEpro

The ELITEpro XC is rated for 600V Over-Voltage Category III. Cat III is for measurements
performed in the building. Examples are measurements on distribution boards, circuit
breakers, wiring including cables, bus bars, junction boxes, switches, and socket outlets in a
fixed installation, and equipment for industrial use. Other equipment could include stationary
motors with a permanent connection to the fixed installation.

CAUTION: Ensure that the sensor current/voltage is within range and the channel is correctly

elevated signals may damage the ELITEpro XC and this will void your warranty.

VOLTAGE CONNECTIONS

1) Before connecting voltage leads L1, L2, L3, & N to the meter, first connect them to dedicated circuit
breakers using either Croc-clips or lead adapters from DENT.

a) Refer to the wiring diagrams in Section 2 for wiring connection specifics. Follow local electrical

codes during this installation.

b) IMPORTANT: Verify the breaker is marked as the disconnect breaker for the ELITEpro XC.

2) Connect lead adapters to the banana sockets at the end of the voltage leads.

3) Connect the voltage leads (L1, L2, L3, and N, as necessary) to the ELITEpro XC.

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 ELITE 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 in the
Appendix.

The following sensor types are supported and selected through the ELOG 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. However, the polarity protection
circuitry 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.

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.

Example Sensor Data Plates

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.

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 the ELITEpro SP, a legacy product produced before ELITEpro XC.
Users of ELOG 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.

DENT Instruments

Quick Start to Using the ELITEpro

1) Connect the wires of your pulse input measuring device to the +/- pulse output connection points on
the ELITEpro SP.

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 name in the Name field to identify your logger (optional).

4) 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 output different pulse 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 output pulses of two Physical
Power Channels, or both may be set to “2.” This enables users to output pulses with different data in the
Value and Scale described in the following sections.

5) 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 outputting pulses for KWh, KVAh, or KVARh. Only one may be outputted at
a time if a single digital output channel is turned on, but users have the option of outputting two
different values concurrently from the same Power Channel if both Digital 1 and Digital 2 are in use.

6) 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.

7) Click SEND SETUP TABLE to Logger.

NOTE: The maximum output rate is five (5) pulses per second, or 5Hz, with a maximum current of 75mA
and 30V DC.

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.

Creating and Using the Logger Setup Tables

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. 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.

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.
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

The ELITEpro XC has four configurable hardware channels corresponding to the current.

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 D—Calculated Power Channel Formulas.

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.

LED Diagnostics

PHASECHEK™ LEDS

PhaseChek is a unique feature of DENT meters that simplifies installation by ensuring proper CT-to­voltage 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).

If the total system 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
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.

If the Physical Power Channel (CT) is turned off in the setup table, the corresponding
PhaseChek LED will be dark.

 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 backwards (-kW) with the arrow pointed away from the load

 LED flashes red and blue—CT is on backwards and on the wrong voltage phase

to be monitored is a

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. Green will flash approximately
once per second when the ELITEpro XC is logging and communicating with the computer.

Power Measurement—Connecting Sensors & Configuring Channels

The ELITEpro XC can monitor AC power loads ranging from 1-phase, 2-wire to 3-phase, 4-wire systems
and up to 600 VAC at 50 or 60Hz.

Read all warning symbols described in the Safety section AT THE BEGINNING OF THIS MANUAL.

Use the proper Current Transformers (CTs) for the load being monitored. For a complete discussion on
this, see the section Current Transformer (CT) Selection below.

CAUTION: DO NOT USE UNSHUNTED CTs. ONLY USE SHUNTED CTS FROM DENT INSTRUMENTS

U.S. color conventions are used in the document’s diagrams. ELITEpro XC meters supplied for
international markets are provided with 5 colors of voltage leads: red, black, blue, white, and
yellow. The voltage lead sockets on the meter are all black in color
N.

The UL listing covers the use of the following DENT Instruments CTs that are UL Recognized and
have been evaluated to IEC 61010
CT-HSC-020-X (20A Mini), CT-HSC-050-X (50A Mini), CT-HMC-0100-X (100A Midi), and the CT­HMC-0200-X (200A Midi), and CTs that are UL listed to UL2808.

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.

This section describes how to connect the CTs and the voltage leads to different service types, and how
to configure the ELITEpro XC channel(s) for monitoring.

1) Connect each CT lead to the channel pins of the black connector termination block.

For each channel, the left connector pin is the positive, or high-side, wire and the right pin is the
negative, or low-side. Connect DENT Instruments-supplied current transformers as follows:

 Split-core CTs (removable leg) and hinged CTs—The white CT wire is (+) and the black wire is (-)

 Clamp-on CTs (clothes pin type)—The red lead is the (+) wire and the black lead is the (-)wire

 RōCoils— The white lead is the (+) wire and the brown lead is the (-) wire (bare wire is shield)

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 drive.

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 retrieve a data file from the logger, 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

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

Appendix

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
ELITEpro XC displays and records displacement Power Factor.

+ VAR2) which does not contain harmonic content. The

97

DENT Instruments

Appendix

If there are no harmonics present, the displacement power factor and harmonic power factor are
identical. If harmonics are present, the harmonic power factor (3 element) will always be smaller than
the displacement 100 power factor (2-element). Similarly, the 3-element VA will always be larger than
the 2-element VA. When comparing the ELITEpro XC three-phase measurements with other meters,
make sure that the same method of calculating VA and Power Factor is used.

Connecting the ELITEpro XC to a 3-phase 3-wire Delta load using the 3 element method:

It is very similar to the 3-phase, 4-wire WYE connection. Use a CT on each phase and connect the three
ELITEpro XC voltage wires to each phase. The neutral wire should then be connected to earth ground.
The Setup table should look just like that of the 4-wire WYE setup. See ELOG Quick Setup Wiring

USB (STANDARD)

A USB connection is the standard (and fastest) connection option for the ELITEpro XC, used locally for
transferring data when a laptop is available in the field.

1) Connect the USB cable to a USB port on your computer, inserting the other end in the USB port on
the ELITEpro XC. If a USB cable is 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.

2) ELOG should launch automatically and connect to the logger. If it does not, click on the icon on the
computer desktop.
