SVM-10 Manual
Foreword
We founded Power Monitors Inc. (PMI) to provide state-of-the art, easy-to-use, and
affordable electronic test equipment to the power industry. Our products have been
developed by working directly with electric utilities to determine their specific needs.
These products are designed for only one purpose: to collect and assist in the analysis of
field-recordable data for electric utilities.
The SVM-10™ was developed with your needs in mind. We created them to meet the
needs of a large utility, and based their unique capabilities on our years of experience
building versatile voltage recording and analysis equipment. Inside lightweight,
weatherproof, rugged enclosures, state-of-the-art electronics measure and record true
RMS voltage on four channel connections. The units require so little power; they operate
on the voltage from one line cord. There are no batteries to recharge prior to use. Each
unit has been individually calibrated to ensure high accuracy and stability over a wide
range of temperatures.
PMI scanners remain the only products on the market that will allow both electronic
“stripchart” recording and a number of specialized recording modes tailored to the
power industry. The specialized reports are merged with unique data collection
techniques to provide accurate information that is easy to understand. Features such as
min/max/Avg recording of voltage make PMI scanners the ideal products for
distribution monitoring.
The Scanner features:
True RMS voltage measurement on each of four channels
Programmable abnormal voltage recording
On-site, real-time display of voltage
Single-cycle response (16 msec)
More than 122,000 samples per second
0-10 volt RMS operating range
Up to 2,048K FLASH EPROM memory
Memory capacity for more than one year of summary data, 500 event
records, 500 records of significant change
Rugged, weatherproof enclosure NEMA 4X
All channels captured simultaneously in one cabinet

SVM-10 Manual
Scanner/WinScan™ graphs and reports include:
Stripchart and histogram analysis for RMS voltage report
Daily Profile
Significant change report
Waveforms (optional)
Because of these capabilities, the SVM-10™ Scanner is the perfect instruments for
analyzing and solving power quality and quantity problems. After looking through this
manual and using your Scanner, please contact us with any questions about its
operation, or with ideas for new features or products. We want you to be happy with this
product, and we always appreciate any input that helps us develop products to meet your
future needs.
Thank you,
Walter M. Curt
Owner, Power Monitors Inc.

SAFETY ISSUES
Please read carefully before installing or using the Scanner.
 The Scanner contains dangerous voltage levels during operation. Do not disassemble
the Scanner. THE ONLY USER-SERVICEABLE PARTS INSIDE ARE THE
BATTERIES! Insure power is completely removed from the unit prior to changing
the batteries.
This device is manufactured for use by trained and qualified personnel only.
Do not install or operate while in contact with standing water or wet ground.
 Wear protective gloves and safety glasses at all times during the installation,
operation and removal of the Scanner.
 During installation, disconnect power from any lines to which the Scanner will be
attached.
 Although the Scanner has been designed and built to be as safe as possible, great
care should be exercised at all times during operation and installation.

1.2 SCANNER DESCRIPTION
1.2.1 General
The SVM-10 Scanner is easy-to-use, true RMS, micro-computer-based voltage
recording device that produce accurate readings and professional reports. These
scanners can help you resolve customer stray voltage complaints, conduct long-term
voltage surveys, and detect voltage variations as brief as one cycle. The Scanner will not
disrupt normal power supply; rather, it uses a minimal amount of voltage from one 120
vac outlet.
Each Scanner gathers and stores stripchart data, recording the average, minimum and
maximum readings for a selected interval with one-cycle resolution. Even events lasting
less than one cycle are revealed in WinScan™ reports if the Scanner is configured to
capture the information.
Installing the Scanner is relatively simple, although using the unit requires the same
attention to safety as working with any other high-voltage device. Once the unit has
been installed and the data you need have been recorded, the data can be downloaded
using either a modem (if your Scanner is so equipped) or serial cable. Real-time data can
be checked using the keypad and liquid crystal display (LCD) on the unit’s front. An
optional Palm®interface is also available for viewing real time data from the unit.
Please refer to the PalmView manual for further information.
You can then view and analyze the data using the WinScan™ software. With the
software you can create an array of graphs and reports, each of which provides you with
useful, clearly presented power data.

SVM-10 Manual
1.2.2 Inputs
Direct hookups are fed into 4 voltage, 0-10vac inputs. Four direct inputs are available to
be recorded and used with reports and strip charts. To record an input, the input must be
selected as a strip chart in WinScan™.
1.2.3 Instrument Size
The Scanner is contained in a standard 6.5 inch (165.1mm) wide x 6.5 inch (165.1mm)
high x 4.25 inch (107.95mm) deep NEMA 4x lockable case.
1.2.4 System Description
The Scanner is a system designed to measure and record AC Voltage parameters using
state of the art digital technology. Signal inputs from AC power connections are
monitored by the system. No pen, ink or paper are required; a graphics display shows
the information. The unit can also be used with PalmView software running on a
Palm® Personal Digital Assistant (PDA) for real time viewing of waveforms, harmonic
bar graphs, vectors, as well as numeric values.
A. Screens and Displays
Screen display styles are available to present data in a familiar format. User instruction
and data entry screens feature easy to use menus, with easy to understand terms.
Operating display screens show information in a logical and easy-to-read format.
B. Day-To-Day Use
Day-to-day operating measurements are stored and recalled instantly. Up to two MB of
standard internal memory allows data to be efficiently and economically stored and
retrieved.
C. Configuration
WinScan™ software allows the user to program the unit quickly and efficiently using an
IBM Windows based compatible PC.
Programming can also be done using PalmScan Software running on a Palm® PDA.
It’s graphical touch screen interface provides straight forward,
user friendly configuration. Strip charts, and Event parameters can be easily
programmed. Other parameters such as Scales, and engineering units are also easy to
program.

SVM-10 Manual
D. Applications
A Scanner may be configured by you to record and monitor almost any voltage
configuration. Typical measurement applications include, but are not limited to:
Voltage Levels
Harmonics to the 51st
E. System Technology
This Power Scanner is a state of the art system, designed around a microprocessor, with
an executable program stored in memory. The memory is used for data and setup
storage.
1.2.5 Memory
Electrically Erasable Programmable Read Only Memory (EEPROM) eliminates the need
for a battery back-up. Programming is stored in EEPROM. In the event of a power loss
or system reset, the programming will be protected.
1.2.6 Clock
The Time-of-Day clock will be maintained indefinitely after loss of line power by an
internal Lithium battery.
1.2.7 Scanner Construction
The Power Scanner features modular construction. All printed circuits boards are
conveniently accessible for fast and simple troubleshooting and/or removal via a lift-out
chassis. The lift-out chassis also facilitates easily changing the LCD. All viewing
controls and indicators are located on the front panel. Servicing should only be done by
an authorized service center of PMI. The PC boards are conformal coated and high
voltage is present, servicing by unauthorized personnel can result in product or bodily
damage.
1.2.8 Communications
The standard RS232 port allows you to
plug the Scanner into your computer
and download the data from memory.
An AC Adapter is also supplied that you can plug
into the 9 pin D shell that will power
the unit for programming or downloads.
This eliminates the need to have AC voltage
