INTRODUCTION
There are four meters in the PowerScout HD Series: the PowerScout 3 HD (PS3HD), the PowerScout 12
HD (PS12HD), the PowerScout 24 HD (PS24HD), and the PowerScout 48 HD (PS48HD). These meters
monitor the voltage, current, power, energy, and many other electrical parameters on single and three-
phase electrical systems. A PSHD meter uses direct connections to each phase of the voltage and current
transformers to monitor each phase of the current. Information on energy use, demand, power factor,
line frequency, and more are derived from these voltage and current inputs.
The PSHD meter is not meant to be a standalone energy recorder; rather, it is connected as a slave
device to a data logger, Remote Terminal Unit (RTU), or Building Management host network. The PSHD
meter communication interfaces include Ethernet (LAN) or RS-485 serial. BACnet MS/TP and Modbus
RTU are the two communication protocols that operate over an RS-485 serial network and BACnet IP
and Modbus TCP are supported over Ethernet. A USB port is also provided as the preferred connection
for on-site configuration and can be run concurrently with an RTU.
Unpacking the Unit
The PSHD can be ordered with optional product features which are identifiable on the part number
label.
PowerScout HD Part Numbering Scheme

Planning for Field Installation
DENT Instruments
PowerScout HD
PLANNING FOR FIELD INSTALLATION
Project Manager Aspects
Meter installation often includes coordination between individuals or groups of people with different
responsibilities. Spend a few minutes considering who will be executing each portion of the installation
and what tools are needed at each stage. Things to consider include determining how to communicate
with the meter, setting address configuration, installing ViewPoint HD, access to PIN numbers, etc. The
more tasks completed before installation the fewer tasks will be needed in the field, where most
mistakes happen. The following section gives an overview of typical process activities followed by details
in the next section.
CONFIGURATION &DATA VIEWING OPTIONS
The PowerScout HD meter has three methods for configuration and data viewing. The most powerful
interface is ViewPoint HD, a Microsoft Windows application that runs on PCs or Tablets. ViewPoint HD is
encouraged for complex installations and is required for configuring advanced functions, like alarms. The
second interface is the PSHD Web App and is intended for smart phones or tablets that can connect to
the meter over USB or Ethernet. The third interface is the optional LCD user interface and is intended for
intermittent end-user observation and is restricted in capability. The RTU can also be used for
configuration if communication settings are already established. The feature set of each interface is
summarized next.

Meter Configuration
DENT Instruments
PowerScout HD
METER CONFIGURATION - DETAILS
This section is written to support setting up the PSHD in an office environment and
configuring the power meter for a pre-determined configuration. In many cases, the
setup is standardized for an organization or project. In other cases, the setup can be
documented and emailed to an installer. The setup can also be performed on-site and
reflect “as-built” configurations.
The PSHD meter cannot be configured using ViewPoint HD over a serial port. RS-485 serial
network configurations must be pre-configured or use Modbus / BACnet hosts.
This section describes the use of the ViewPoint HD Windows Application. If this interface
cannot be used, refer to the section on using the simplified
PSHD Web App interface. The web
browser can be accessed from the USB port to support macOS users.
Install the ViewPoint HD Software
The following directions assume that this is a “fresh” installation of ViewPoint HD software. If you are
upgrading ViewPoint HD from a previous version, follow the Uninstallation Procedure at the end of this
section prior to installing new software. Instructions can also be found in the UPGRADE INSTALLATION
READ ME.txt file accompanying the ViewPoint HD installer.
Insert the ViewPoint HD thumb drive into the computer or download from
Locate the ViewPoint HD Installer folder and copy it to your desktop. Running the installer directly from
the USB drive or from a server location may lead to the installation being unsuccessful.
TYPICAL INSTALLATION
Double-click the “RunMe to Install ViewPoint HD.bat” batch file to install ViewPoint and its support files
in Windows default locations. This option works for most users.

DENT Instruments

Meter Configuration
CUSTOM INSTALLATION
For users who want to specify the location of the ViewPoint HD software and support files, double-click
the folder “Install Files” and run setup.exe. This will prompt the user for additional details. Selecting the
run setup.exe instead of the batch file also requires users to run a separate installer for the LabView
RunTime engine located within the LVRTE folder. This second step is handled automatically in the batch
file.
INSTALLATION TROUBLESHOOTING
Successful installation of ViewPoint HD may be prevented by settings specific to your PC for the
following reasons:
1) Anti-virus protection software may interfere with the installation of ViewPoint HD. If the
installation does not complete for this reason, try temporarily disabling the virus protection
software on your PC and re-attempt the installation.
2) Administrative Access. In some cases, user privilege settings may disallow the installation of new
applications. This may require logging in as an administrator.

UNINSTALLATION PROCEDURE
If ViewPoint HD software had been previously installed on a computer, installation of a new version of
software “over the top” of an existing version of ViewPoint HD may not replace all the support files
required to run the software properly. Therefore, it is recommended that you uninstall previous versions
of ViewPoint HD prior to updating the software.
Uninstallation is a two-step process which involves 1) removing ViewPoint HD using Windows and 2)
deleting the ViewPoint HD folder from your hard drive.
1) Open the Windows Uninstaller (Windows 10: Go to Add or Remove Programs under
System Settings)
2) Search for ViewPoint HD or scroll down the program list to locate the program
3) Select the ViewPoint HD application and press the Uninstall button
After uninstallation is complete, perform the final steps to completely remove program’s support files
from your hard drive:
1) Open Windows File Explorer and navigate to the Local Disk (typically C:)
2) Delete the folder titled “ViewPoint HD”
Once the program has been uninstalled and the support files have been removed, follow the Typical
Installation instructions at the beginning of this section.
CONNECTION &CONFIGURATION OPTIONS USING VIEWPOINT HD
When the ViewPoint HD application is launched, it will prompt the user to select one of four
connectivity options.
•Connect over USB cable
•Connect over Ethernet to a Predetermined IP address
•Scan Network for Meters
•Create Setup file only (no meter connected)
Note: The USB connection method is recommended for new users who have physical access to the
meter and the appropriate USB cable (supplied). Check out this option first!

USB CONNECTION (POWER &COMMUNICATIONS)
1) Connect the PSHD meter to a USB port of your computer to provide both power and
communications.
a. If equipped, the LCD user interface is the most visible indication of a running meter.
b. For meters without a display, a green flashing LED on the circuit board indicates that the
PSHD meter has booted and is running.
c. PS12HD, PS24HD, and PS48HD meters draw 500mA from the USB port which may
overload “out of spec” USB hosts. If the meter fails to power, or flickers when powering
over USB, an alternate configuration for power must be used.
d. PS3HD meters draw 150mA from the USB port and should not require any additional
external power when connected via USB.
A to B Cable
For use with PS12HD/PS24HD/PS48HD
A to C Cable
For use with PS3HD
Preferred Connection via USB Cable
2) Launch the ViewPoint HD application and press the “CONNECT OVER USB” button on the pop-up
window.
The meter should now be communicating. The ViewPoint HD application offers visual guides and context
help to facilitate meter configuration. Please read the ViewPoint HD overview section (below) or watch
the tutorial videos for additional information on configuring the meter. By default, PSHD meters are
configured for DNS Ethernet addressing. A very common configuration sequence is using USB to
configure a meter for Ethernet communications at a static IP address and then switching from USB over
to Ethernet to locate it. This is facilitated in ViewPoint HD by pressing the “Connect to Another Meter”
icon located in the upper right-hand corner.
