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. For inquiries contact the Dranetz Customer Service Department at (732) 287-3680 or 1-800-372-6832.
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.

Overview, continued
HDPQ Xplorer user interface (continued)
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. 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.

WARNING
WARNING
WARNING
To avoid the risk of electric shock or burns, always connect the safety (or earth) ground before making any other connections.
To reduce the risk of fire, electrical shock, or physical injury it is strongly recommended to fuse the voltage measurement inputs. Fuses must be located as close to circuit connection as possible to maximize protection.
For continued protection against risk of fire or shock hazard replace only with same type and rating of fuse.
Do not replace fuse again if failure is repeated. Repeated failure indicates a defective condition that will not clear with replacement of the fuse. Refer condition to a qualified technician.
Contact Dranetz Customer Service for more information on the fused voltage adapter. Refer to Dranetz Information Sheet titled Fuse Voltage Adapter 1000V AC/DC FVA­1K1 & FVA-1K4, P/N 899220.

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 Engineering units (volts and amps). Frequency components of harmonic graphs can be displayed either in Hertz or in Harmonic Number. The graphs can be zoomed and rescaled.
Harmonic Table measured values: frequency and harmonic number; magnitude in Engineering units and percent of fundamental; phase in degrees (for harmonics only). Harmonic table values are displayed in order of ascending frequency, and can also be sorted in order of descending magnitude.

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.
