INTRODUCTION
The Dranetz-BMI PowerXplorer® PX5, Power Guide 4400, and the Power Visa are three
portable, hand-held, eight-channel power quality meter/monitors, very similar in operation
though the PX5 and 4400 have some additional parameters not in the Power Visa, and the PX5
has a high speed sampling board for capturing the details of very fast transients. The common
features are covered in this document, and the PX5 name will be used to represent all three
instruments. These cutting-edge power quality instruments are designed with a
color liquid crystal display (LCD) 1/4 VGA, using touch screen technology. They can
monitor, record and display data on four voltage channels and four current channels
simultaneously.
PX5 is designed to meet both the IEEE 1159 and IEC 61000-4-30 Class A standards for
accuracy and measurement requirements. It can do PQ-optimized acquisition of power
quality related disturbances and events. It is designed with a statistical package called
Quality of Supply (QOS), with monitoring and setup protocols set to determine voltage
measurement compliance required for EN50160 monitoring. European standard
EN50160 requires that measurement parameters must be within a specified percentage
for 95% of the time.
The PX5 firmware can monitor power quality phenomena for troubleshooting and/or
compliance purposes. It can record inrush conditions, carry out long-term statistical
studies to establish performance baselines, and perform field-based equipment testing
and evaluation for commissioning and maintenance. The firmware integrates an
intuitive instrument setup procedure to ensure the capture of all relevant data for
additional post process analysis, report writing, and data archiving using other
compatible Dranetz-BMI software applications such as NodeLink® and DranView®.

Quick Reference Guide for PowerXplorer / Power Guide / Power Visa pg 7
1. Voltage and Current Connections – there are four differential voltage and four differential
current channels, which can be wired to measure a variety of circuit configurations. Use
only Dranetz-BMI voltage leads and current probes for proper operation. Do not exceed
marked ratings.
2. Graphic Color LCD with Touch Screen – the color LCD has an integral touch screen that
is used to select functions for setups, real time meters, and viewing stored data. Either a
clean finger or a PDA-type stylus can be used and the screen should be calibrated with
whichever you are going to use by selecting Preferences; Display Preferences, then
Calibrate Touch screen when first turned on. Clean only with soft cloth.
3. Field Replaceable Battery Pack – the internal UPS feature requires that the internal
batteries be properly charged and maintained. If the battery pack is in need of
replacement, de-energize the connections and power to the unit before opening the
battery door and replacing the pack only with the Dranetz-BMI battery pack PN# BP-
PX5. A spare battery pack may be useful to have.
4. Memory Card slots for data and firmware updates – the Dranetz-BMI supplied Compact
Flash memory cards are used for data storage, as well as to upload new firmware
versions when available. Use only Dranetz-BMI supplied memory cards, as the speed

Quick Reference Guide for PowerXplorer / Power Guide / Power Visa pg 8
requirements of the instrument can not be satisfied by many off-the-shelf memory cards.
Do not remove the memory card while monitoring. Only one slot is active at a time.
5. There are three status LEDs and the ON/OFF switch (push for on, push for off) are
located on the bottom of the instrument. AC power connection for charging the battery
and powering the unit with AC Adapter 117029-G1 is located on the right side of the
instrument. From left to right, the LEDs are:
•3 Battery Charge Indicator. LED will light steadily while battery is fast charging
and blink when fully charged.
•4 Status Indicator. LED will light steadily when abnormal condition is detected.
The unit is operating normally when light is off.
•5 Power Indicator. LED will blink in a heartbeat fashion (once per second) when
the unit is operating normally.

Connecting Voltage Measurement Cables
Measurement cable set
Description: Voltage measurement cables are provided as standard accessories and are
stored in a cable pouch as part of the measurement cable set, P/N 116042-G3. Each
cable set consists of a cable and alligator clip.
Voltage Rating: Direct connection of all voltage measurement cables are rated at 600
Vrms max. For measuring voltages greater than 600 Vrms, potential transformers (PTs)
must be used.
Optional fused voltage adapter
There are two optional fuse accessory kits available for use with the measurement
cables for PX5. One kit (P/N FVA-1) contains one fused voltage adapter and one
measurement connecting Red cable 50 cm in length. The other kit (P/N FVA-4) contains
four voltage adapters and four measurement connecting cables 50 cm in length (one
Red, one Yellow, one Blue, and one Grey).
•WARNING: To avoid the risk of electric shock or burns, always connect the safety (or
earth) ground before making any other connections.
•WARNING: 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 the load as possible to maximize protection.
•WARNING: For continued protection against risk of fire or shock hazard replace only
with same type and rating of recommended fuse. Use only fast blow type fuse which is
rated 600V. Recommended fuse type is Littelfuse, part number KLKD0.30 rated 600V
AC/DC, 0.3A fast blow.
•WARNING: 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.

USER INTERFACE
The instrument powers up with the Home Page screen, shown above. The top portion of the
screen is for status information, including: monitoring status (on, off, or armed); what type of
circuit is being monitored; the memory card status (not inserted or percentage full); the data file
name; the number of waveform cycles saved (indication of event activity); number of journal
records saved (periodic timed storage of parameters); and, the real time clock display.
The first row of icons are referred to as Real-Time-Meters, showing the instantaneous values of
the parameters. The second row of icons are for display of stored data, either through trend
plots, event waveforms and rms plots, and reports of either EN50160 data or an annunciator
panel of user selectable parameters and their state (normal, out of limits). Also in this second
row is the icon for setting up instrument parameters, such as time/date, memory, language,
LCD, and touch screen.
In the bottom of the screen is a button for Start menu, which allows for starting to monitor from
either the existing setup, recalling a stored setup from the memory card, or going through the
setup process again, either in automatic setup mode, or the step-by-step wizard.

OTHER INSTRUMENT SETUP
Functions, such as the time/date, which language, communication port setups, and LCD
settings can be changed from the Instrument Settings menu, as well are formatting a memory
card. This screen is activated from the PREFERENCES icon on the Home page.
------------------------------------------------------------------------------------------------------------------
REAL TIME METER MODES
Scope mode
Scope mode functions as an oscilloscope, displaying real-time waveforms of voltage and
current for up to eight channels simultaneously, with one second update rate. The colors
of waveform display are user programmable. Scope mode also provides a textual
display of rms values, division for axis values, and frequency.

Quick Reference Guide for PowerXplorer / Power Guide / Power Visa pg 15
Meter mode
Meter mode functions as a true rms voltmeter and a true rms clamp-on ammeter.
Voltage and current measurements, along with other calculated and advanced power
parameters, are displayed on the Meter mode screens in both textual and graphical
format.
Harmonics
Harmonics display the amplitude and phase of each harmonic to the 63rd harmonic in
both graphical and textual format. User can select which parameter to show the
harmonics for (V,I,W), which channel (A,B,C,D), zoom in a the 5Hz components, set
options such as showing harmonics and/or interharmonics and displaying in Hz or
harmonic number, scaling to the fundamental or absolute value, and a list of the
harmonic magnitudes and phase angles in tabular fashion.

Quick Reference Guide for PowerXplorer / Power Guide / Power Visa pg 16
Phasor diagram
The phasor screen displays a graph that indicates phase 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
rotations demonstrating resistive, inductive and capacitive loads can be displayed.
-----------------------------------------------------------------------------------------
STORED DATA FUNCTIONS and DISPLAYS
Trend
Users can generate plots for all journalled data combined with min/max recordings of
that parameter. Most journal parameters have multiple channels to plot.

Quick Reference Guide for PowerXplorer / Power Guide / Power Visa pg 17
Events An event occurs when a programmed threshold limit is crossed. An event
consists of the pre-trigger cycle(s), trigger cycle(s), and post-trigger cycles(s)
The event data for all of the captured channels can be displayed in time plots of
the rms values or waveforms, event details such as trigger conditions,
characterization of the event according to PQ standards, and min/max values, or
