I. General Layout & Functionality
a) The PowerPad™ has been laid out with ease of use and maximum functionality in mind. Looking at the top of the
unit from left to right, the unit has three current inputs (A Phase, B Phase, and C Phase) and four
voltage inputs (A Phase, B Phase, C Phase, and Neutral) (Figure 1, bullet 1). One thing to note is
that the Current Probes are intelligent. The unit auto-detects and auto-configures itself according to which probes
are connected to it.
b) Just to the right of the display on the right-hand-side is an optically isolated RS-232 port (Figure
1, bullet 2). This allows the user to simultaneously connect to a power panel and computer. This can be
accomplished, without the possibility of danger due to an accidental fault.
c) Just below the RS-232 port is a power port (Figure 1, bullet 4). This supplies power to the unit and
charges the internal NiMH battery pack. The battery pack has a 10-hour operational capacity and can be
charged at any level of discharge. Power to this port can be 120/240V, 50/60Hz. PowerPad™ can be used while
charging.
d) There are four operational menu buttons (light gray buttons) located on the lower left front panel.
(Figure 1, bullet 10) From top-to-bottom they are SETUP , SNAPSHOT , PRINT ,
and HELP .
e) The blue buttons on the bottom right are the MAIN MODE function buttons . (Figure 1, bullet 9) From
left-to-right and then top-to-bottom they are: TRANSIENT MODE , HARMONIC MODE ,
WAVEFORM MODE , ALARM MODE , RECORDING MODE , and POWER/ENERGY
MODE .
f) There are six sub-menu buttons just below the screen (Figure 1, bullet 6). These allow the
user to choose the sub-menus available in a particular menu mode. The function for each of these buttons
change according to the display function or mode in use. The sub-menus available in the waveform mode can be
seen in (Figure 1, bullet 5)
g) The arrow keys allow the user to move within the menus such as the side-bar menu seen on the
right-side of the display (Figure 1, bullet 3)
h) The enter button allows the user to choose and enter changes to the setting within the menus.
(Figure 1, bullet 7)

II. Setup
a) Once the unit is turned ON, by pressing the green button (Figure 1, bullet 11) in the bottom-left-hand
corner, the unit powers up and defaults to the Waveform Mode , which is the top-left of the six blue
main mode function buttons (Figure 1, bullet 9). Date, time and battery capacity are displayed in the
top-right-corner of the screen .
b) The user can depress the SETUP button , the top button on the left side, to configure the instrument
(Figure 1 bullet 10). There are 11 options in the setup. One option to note is the Electrical Hookup. Use the
arrow keys (Figure 1, bullet 8) to scroll down and press the ENTER key (Figure 1, bullet 9). You
should see a screen similar to Figure 2. Figure 3 shows the example of the screen seen while configuring the
instrument using the DataView®software.

To change the setup using the panel, simply scroll through the options using the arrow keys (Figure 1,
bullet 8) and pressing the ENTER key (Figure 1, bullet 9) when the desired function is highlighted.

III. Operational Examples
a) Assuming that the unit was connected using a 4-wire WYE setup to a three-phase circuit, scrolling through the
OPERATIONAL menu buttons (blue buttons) (Figure 1, bullet 9) (from left to right) would result in the
following screens examples. Note: Alarms example is not shown.

IV. Additional Information
The PowerPad™ is a stand-alone unit that comes standard with the Dataview®software. The unit can be remotely
controlled using the software for operation and configuration. The Dataview® software adds a significant amount of power
and versatility to the unit. It also features automatic report generation that allows the user to go from data download to
report in three mouse clicks, using the factory supplied templates. The user can also create custom templates to meet
the needs of the application.
Each unit comes fully equipped with all the accessories needed. Users choose a particular package depending on which
current probes that they would like to use with their unit.
