The trademark shown is hereinafter referred to as HDPQ throughout this User Guide.
The Xplorer, Xplorer-400, Guide and Visa are portable, hand-held, eight-channel
power quality meter/monitors which are very similar in operation, although the Xplorer
also has a high speed sampling board for capturing the details of very fast transients.

NOTE: This User Guide provides information on the features and functionalities for
Dranetz model HDPQ Xplorer. Functionalities of other product models are each
specified in its own user guide.

The HDPQ Xplorer portable, hand-held, eight-channel power quality and energy meter/
monitor is capable for use on three user interface (UI):

• Local/LCD Touchscreen UI - with a WVGA wide screen liquid crystal display
(LCD), using touch screen technology.

NOTE: This User Guide provides information on this local user interface, which
includes the touch screen, LCD, and three touch buttons below the screen. The other
interfaces below may differ due to size and device capabilities, and are to be specified
in a separate document.

HDPQ Xplorer
firmware

• Remote UI - uses the remote desktop communication and other “apps” on personal
computers/laptops/tablets. Remote navigation using a computing device with a full
size screen such as laptop computer, desktop computer or tablet computer, typically
7" or larger display. The remote UI allows for complete control of the instrument to
the full extent of the instrument capabilities, including on screen 'touch' controls and
the three touch buttons below the display. On remote PCs with a keyboard, the F1,F2
and F3 shortcut keys map to the instrument's report and help panel buttons. Major
differences between local and remote UI is in the navigation and controls that are
different on the instrument’s touch screen versus mouse clicks on personal computer
or laptop. On tablets, some of the controls used for screen navigation do not apply.

• Remote Mobile UI - uses personal communication devices such as mobile and smart
phones. Compatible with devices such as Smartphone or equivalent devices with
small, typically 3” to 4" display. The capabilities are based on various “apps” that the
user can download from the Dranetz web site, like viewing real time and stored data
in a format compatible with smaller display.

The firmware for HDPQ Xplorer is contained on internal FLASH memory. It has an
operating system capable of performing multiple applications. When an updated
version of the firmware is released, you can upgrade the internal program by
downloading the latest firmware version. See page 1-12 for instructions on how to

upgrade the HDPQ Xplorer firmware.

voltmeter, a true rms ammeter, and a watt meter. Voltage,
current, power measurements, along with hundreds of other
calculated and advanced power and power quality parameters,
are displayed on the meter screens in textual/tabular format.

• Scope Mode - Scope mode functions as an oscilloscope,
displaying real-time waveforms of voltage and current for up to
eight channels simultaneously, updated at approximately once
every three seconds. The colors of waveform display are user
programmable. Scope mode also provides a textual display of
rms values, division for axis values, and frequency.

• Dashboard - Dashboard presents a visual way of seeing present
values as well as if any events occurred, such as out-of-limit
conditions, for each of the displayed parameter. The dashboard
displays status summary for Power Quality, Energy/Demand,
and Motor Quality parameters. It displays meter data (or event
count) in a 3x4 matrix. It is also color coded to indicate whether
or not the parameter is within limits.

• Phasor Diagram - The phasor screen displays a graph that
indicates phase and magnitude relations between voltage and
current based upon the angles at the fundamental frequency, as
determined by Fourier analysis. Phasor diagram displays voltage
and current phasors for all channels.

Functioning as a phase angle meter, the unit can display system
imbalance conditions and provides such information in textual
form also. The phase angle display can also verify if monitoring
connections have been made correctly. Animated phasor demo

Dial Meters

Introduction

Dial meters

Dial Meters allow you to define the parameters and create dial-type readings of each
channel or parameter. The readings are updated at approximately once every three
seconds.

The Dial Meters screen can be displayed by pressing Dial Meters from the Real-Time
Data menu. Six dial type meters can be displayed for any of the channel/parameters that
are journalled. By default, the instrument shows dial-type readings for the voltage (V)
and current (I) parameters - Va, Vb, Vc, Ia, Ib, Ic. Axis (end points of meter) can be
changed on per meter basis and journal limits can be shown as bands of colors on the
dial face.

Harmonics

Harmonics
display

HDPQ Xplorer allows you to view voltage and current harmonics/interharmonics in
graphical or in tabular form. Harmonics are waveform distortion, steady-state
deviations from an ideal power frequency sinusoid and are characterized by the spectral
content of the waveform. Interharmonics are frequency components between the
harmonic frequencies. The IEC 61000-4-7 and IEEE 519 Standards dictate that
harmonic analysis is done using a synchronous window of 10 cycles for 50 Hz, or 12
cycles for 60 Hz. This results in bins which are nominally 5 Hz wide. The actual width
of the bins is equal to the actual frequency divided by 10 if the nominal frequency is 50
Hz, and 12 if 60 Hz. For example, if actually operating at 49.9 Hz, the bin is 4.99 Hz,
but is labelled “5 Hz” as specified by the standard.

You can determine the number or range of harmonic frequencies to trend and view in
detail. There is also the option to select how to plot harmonic/interharmonic data and
specify the units of measure by which harmonic data is calculated.

Harmonic Graph
and IEEE 519. You can choose the unit of measure by which harmonic data is
calculated and graphed, based on a Percentage of the fundamental value or in

grouping, for example, if there was a 3rd harmonic (150 Hz) of 10%, and the value of
the 145 Hz bin was 1%, and the value of the 155 Hz bin was 2%, then the value
reported in the bin labelled “150 Hz” would also include contributions from the 145 Hz

Automatic Setup for Power Quality

Automatic Setup
procedure

Automatically configures the setup for monitoring quality of supply based on IEEE and
IEC typical trigger settings. Automatic Setup is a one-stop process using pre-defined
values to set up the unit automatically. You have the option to view the summary list of
parameter settings, change probe types if current will be monitored, and/or proceed
directly with data monitoring. Follow these steps to perform Automatic Setup for PQ.

Action... Result...

STEP 1: From the Start Menu,
press Automatic Setup for
Power Quality. The auto­configured circuit type, nominal
voltage, current and frequency
values appear on screen. The
remaining free space in GB is
shown, and you have the ability to
specify the name in which the PQ
setup file can be saved.

• To view the list of parameter
settings for Automatic Setup, press
Summary. Proceed to Step 2 on
page 4-5.

• To display/change probe types for
current monitoring, press Probes.
Proceed to Step 3 on page 4-5.

• To display real-time waveforms of
voltage and current for enabled
channels, press Scope. By default,
the Scope diagram is already
displayed at the bottom right
corner of the screen.

• To display voltage and current
phasors for all enabled channels,
press Phasor. The Phasor diagram
replaces Scope at the bottom right
of screen.

•Press Accept to save any changes
made and return to the Home
Monitoring page with monitoring
ON.

•Press Exit to return to the Start
Menu without changing the
monitoring status.

NOTE 1: If the message “No valid wiring
configuration found” comes up, you must
connect the inputs to a live circuit or override
circuit type in the Wizard Setup. You need to
configure the circuit type appropriate to your
application.

NOTE 2: List of default settings for Automatic
Setup for Power Quality can be found in
Appendix B Technical Specifications.
