Rev 1.5 8

Safety
Operation of the PowerMaster®and the supplied accessories and adapters can present the user
to potentially hazardous conditions. Please follow all required safety procedures set forth by the
user’s safety organization within the company. If no safety organization exists, please follow all
applicable OSHA rules and standards for PPE (Person Protective Equipment) when working in
high voltage and low voltage environments. This equipment should be used by trained and
qualified personnel ONLY.
The protection rating is reinforced insulation per IEC 61010-1 3rd Edition (2010-06), Category IV
600V.
Per IEC 61010-1 3rd Edition –
Measurement Category IV (CAT IV) is for equipment installed at or near the origin of the
electrical supply to a building, between the building entrance and the main distribution board.
Such equipment may include electric power meters, current transformers, and potential
transformers.
Probes - only use probes meeting the manufacturer’s specifications. Using probes that do not
meet the manufacturer’s specifications may be a safety hazard or could invalidate the product
warranty.
Making Connections
1. Press the PowerMaster® ON key, and wait until the Main Menu is displayed.
2. Connect the voltage leads, current leads, and CT probes to the metering service.
3. Proceed with testing.
Safety Tips for Testing:
1. The jack screws used to secure the banana cables to the DIRECT CURRENT connector
MUST be screwed down at all times during testing. This process prevents the possibility
of arc flash from an open secondary in situations where the current leads become free of
the front panel while still inserted into the test switch
2. Verify the probe is rated for the voltage and current being tested (see Section 2.7 for
probe specifications). Only use probes meeting the manufacturer’s specifications. Using
probes that do not meet the manufacturer’s specifications may lead to a safety hazard.
3. Never connect a probe around a conductor or connect to a live terminal before terminating
it to its cable and to the PowerMaster®.
4. For LiteWire probes, verify the fiber optic cable is clean to prevent surface arcing. For
cleaning and maintenance information, refer to the Amp LiteWire or Volt LiteWire manual
supplied with the probe.
5. When using LiteWire probes, verify the hot stick being used has been certified previously
to prevent high voltage arcing.
WARNING
Rev 1.5 9

6. When inserting duck bill probes into a test switch, short the CT secondary (+) first by
pulling the test switch in an open position. This will prevent possible arcing.
7. For clamp-on probes, clean contact surfaces and then snap and release the jaws to verify
a metal-to-metal contact of the jaws (dirt and grease may contaminate the surfaces).
8. For flexible probes, take care to pad mount CT installations. Always wear appropriate
PPE when inside the CT installation.
9. For pad mount CT installations, be wary of various items around the installation (chairs,
tables, etc.) which can potentially become a safety hazard.

1 Introduction
The PowerMaster®3 Series is a handheld field instrument with a true 3-phase analyzing
standard. There are two versions of the 3 series, the 3301, and the 3302. The 3301 has the
ability to do customer load meter testing, register and demand testing, and provides access to
vector diagrams, waveforms, and harmonics. The 3302 has the same ability, but also adds CT
and PT burden measurement, CT and PT ratio testing, and direct current inputs.
Accuracy
With an accuracy of ± 0.05% on direct current channels and ± 0.10% accuracy on the probe
channels, the PowerMaster®is 4 times more accurate than most meters.
User Interface
The user interface is a Windows CE based program that enables the user to perform complex
tasks with an easy-to-use dashboard. This allows the user to either select the appropriate test
within the list, or select "Integrated Site Testing" which incorporates all tests together in a step-by-
step process. Hot keys on the front panel are used as shortcuts to quickly view the vector
diagram, power meter, waveforms, and harmonics at any time during testing. With features
designed to help the meter technician with their job, this user interface is a tool for beginners to
metering that normally was designated to seasoned technicians and engineers only.
Integrated Site Testing
Using Integrated Site Test, the user can easily test the entire site using a step-by-step process
that eliminates mistakes and proves the installation is operating accurately. Integrated Site Test
allows the user to perform tests in sequence that are built into the PowerMaster®. The user will
have the option to customize each test for a particular site, which can be associated to any site in
the database. These test setups can be created and customized as many as required.
Instrument Transformer Testing
Some of the most powerful features of the PowerMaster® are in the Instrument Transformer
Testing section. The PowerMaster®3302 has the ability to sequentially test all three CTs and
PTs in the metering circuit. Using the Hot Keys, the user can quickly view the power pairs
(secondary and primary) for diagnostics. Each test displays the graphs of the ratio and the
parallelogram for all phases on one page. A brand new feature limited to the 3302 as well is the
ability to measure the total burden on the circuit. With a simple quick test, the total burden of the
CT circuit can be measured and analyzed to determine the potential for an overburdened CT.
With the introduction and inclusion of the 303/335 accessory, customers can also now perform a
burden added test, with added burden points of 0.1, 0.3, 0.5, 1 and 2 ohms.
Customer Load Meter Testing
In accordance with ANSI C-12.1-2001 using Method 3 (5.1.5.3), a customer load test can be
performed. The PowerMaster® can determine within seconds how accurate the meter is under
real-world conditions. Determining this accuracy is incredibly valuable since the customer is
being billed under these conditions.
Phantom Load Meter Testing
With the inclusion of the 305/335 accessory, customers can now perform a phantom load test
with current only up to 5A.
Hot Keys
The user can easily access important functions at any time in the PowerMaster®with a push of a
button. The 1) vector diagram, 2) power meter, 3) waveforms, and 4) harmonics all have
dedicated buttons on the PowerMaster®front panel. These keys can be alternatively accessed
using a PC/laptop or USB keyboard via function keys (F7-F10 respectively).
Rev 1.5 16

Database
The PowerMaster®has a built-in SQL database that can hold all information pertaining to the site
including (but not limited to) the meter, CT, PT, AMR, account number, address, substation, GPS
locator, billing multiplier, and when the site needs to be tested again. The user can easily select
a pre-loaded component (meter, CT, PT, etc.) from our large database or create a new
component to be associated to each metering site. Using the Meter Site Manager PC software,
this information along with data results can easily be synchronized to the master database or
formatted into a .csv or .txt file for exporting into the utility’s master database. The real power of
having a built-in database inside the PowerMaster® is the ability to create a daily "route" of tests
for the user that can be setup in the shop (or synched from Meter Site Manager) before going into
the field.
Hardware
The PowerMaster®can be stored in a compact Pelican case, which is waterproof, weather tight,
and extremely rugged. The large buttons are on a tactile key panel creating a splash-proof
membrane. A keyboard and mouse can be alternatively used instead of the key panel, which
allows the user the freedom of operating the PowerMaster® identical to a PC. Implementing a 5.7
inch, full color transflective VGA display allows the user to view the data and operate much easier
in full sunlight. It also prevents eye strain found in other products with small, black and white
displays.
Rev 1.5 17

2 Product Description
This section gives the user a brief tour of the PowerMaster®. It describes the various keys and
their functions, the input and output ports, and the standard accessories supplied with the
PowerMaster®. Optional accessories are discussed later in Section 2.7.
2.1 Keypad
The PowerMaster®keypad uses 37 function keys. Descriptions of all keys are discussed below:
To turn the system on, press and hold down the Power key located at the top right of the
PowerMaster®screen until the green LED embedded in the key turns green. Once powered,
pressing the Power button again turns the system OFF. The PowerMaster®incorporates a power
conservation function. If no activity (keystroke) occurs within 1 minute following the Power
keystroke, the PowerMaster®will go into “sleep” mode in which the display is turned off. Any
tests in process will not be affected. To restore the display press any key.
The HOT KEYS are used to quickly access the power data at any time while using the
PowerMaster®. All hot keys are located to the right of the display. The key functions are: 1)
waveform display, 2) vector analysis, 3) power meter, and 4) harmonics, respectively. For more
information on the hot keys, see Section 8.
Rev 1.5 18

The Function keys (F1 - F6) are located directly below the PowerMaster®display. Six rectangular
boxes on the display directly above the function keys define their use as it corresponds to each
screen. The purpose of each key may change from screen to screen. If any of the screen boxes
are blank, the box’s corresponding key has no function in that screen.
The TAB key moves the cursor from one field to the next field.
The BACK TAB key moves the cursor from one field to the previous field.
The DROP-DOWN key enters the drop-down box menu once the cursor is focused on that field.
All available selections are displayed at the time of keystroke. This key also checks and un-
checks checkboxes. Press the key a second time to select an item and close the dropdown list.
The PREVIOUS key is used to allow the user to go back to the previous screen. Continually
pressing this key will always take the user back to the Main Menu.
The DIRECTIONAL keys are used to move the cursor up or down in a menu selection. Also, the
keys are used to make selections in a drop-down box. These keys can be used alternatively to
view selections in a drop-down box without having to press the DROP-DOWN key.
The BACKSPACE key will delete one character at a time in a reverse direction OR delete the text
in the field entry all together if highlighted
PAGE UP and PAGE DOWN keys are used to move the screen either up or down one page.
This function is available if information exceeds the first page of the screen.
The ENTER key is used to accept data or a menu selection.
Rev 1.5 19

The SPACE key is used to place a space in between text fields and can also be used to
check/uncheck checkboxes.
The ten alphanumeric keys (0 through 9 / A through &) are used to input alphanumeric values into
the PowerMaster®. A single press followed by a one-second delay returns the numeric value
(first character of the key. Two rapid presses followed by a one second delay returns the second
character (first of the three alpha characters) of the key. Three or four rapid presses followed by
a one-second delay returns the third or fourth (second or third alpha) characters of the key,
respectively. For example, if you want to type the letter “N” which is the third character on its
corresponding key, press the key three times rapidly, and then stop for one second. The letter
“N” will appear on the screen.
The symbols keys operate the same as the alphanumeric keys. These keys will normally be used
when entering notes and comments in the PowerMaster®. Note the “period” key (second from
left) is used to help enter the Kt value of the meter (ex. 1.8 Kt).
The battery indicator is located on the unit’s front panel and features four notifications.
1. Charging: Light blinks green
2. Fully Charged: Solid Green
3. Almost Depleted: Yellow
4. Battery Dead: Red. At this point the unit shuts down and will not turn on until A/C power is
reconnected.
