Q : Ever
wondered how much of your money goes in to your
wall socket ?
A : Watt-X™ can help you find out ...
Watt-X™ electricity meter will show you how efficient your home appliances
are. A large LED display counts consumption by the
Kilowatt-hour . You can estimate your electricity expenses for
any period of time. Watt-X™ accumulates the energy reading
and saves it into nonvolatile storage memory. In addition,
this energy meter can automatically calculate and display the cost of
total energy consumption (model 102) or generation (model
103). All these features make Watt-X™
indispensable tool in electricity usage assessment.

information |
 |
|
This
electricity meter is designed in compliance with international standard
IEC1036 (1996-09) and ANSI C12.16 standard – Alternating
Current Watt-Hour Meters for Active Energy, (Classes 1 and 2).
The instrument does not need any specific installation or
adjustments and it is an easy to use plug & play tool. An
energy meter of this type is used in a variety of
applications.

Valuable
features
|
Automatic energy cost calculation by
adjustable $ / kWhr constant
 |
Three
buttons on the front panel of the electricity meter allow the User to adjust
electricity cost constant, which is then used by the
instrument to calculate electricity cost. The display
will toggle between kWhrs and $, when the cost
constant is set to a non-zero.
|
|
|
Nonvolatile
memory for storage of energy reading and $/kWhr constant
|
Build-in
EEPROM inside the energy meter holds all data safe.
Constants, cost
calculations and energy reading is preserved even
after long power outages.
|
|
|
Bright
red numerical LED display with large ½” digits
|
The
display can be seen with excellent quality under any
ambient light conditions and especially at dark
places, like the ones behind refrigerators and stoves.
This type of display does not require ambient light to
be seen and its viewing quality does not dependent on
the viewing angle, which is a common problem with LCD
type displays.
|
|
|
High display
resolution - 0.001kWhr
from 0 to 9.999 kWhrs
|
Watt-X
electricity meter display resolution allows for immediate response to
changes in load conditions. Thus the energy reading
could be observed in nearly real time speed and the
User will not have to wait hours before anything on
the display changes. The high resolution mode is
effective from 0 to 9.999 kWhrs , then it changes to
0.1 standard resolution.
|
|
|
Load
intensity indication
|
Load
intensity is indicated by a flashing LED. As the
electricity load turns larger the LED flashing
frequency increases.
This feature works independently from energy
reading updates, so intensity pulses can be seen even
before the display changes at all, thus providing
immediate information for the presence of electricity
usage.
|
|
|
Field
calibration
|
The
instrument does not require calibration and will
perform according to the class standards without any
need of additional adjustments. However if better
accuracy is expected the instrument could be easily
calibrated at steady load conditions.
|
|
|
Bi-directional
energy detection
|
This
feature is a hardware option. The electricity
meter with reverse detection measures generated energy only. The energy direction
sensitivity is fixed in hardware and not User
selectable feature.
|
|
|
Quality
design and manufacturing
|
Watt-X
electricity meter is manufactured in U.S.A. with high quality
parts and materials. Product optimizations are constantly
being made in order to reduce production cost and
offer lower prices to our customers.

* Watt-X Electricity Meter utilizes state of the art
technology. It measures real energy by sampling instantaneous
power signals from the load and applying subsequent digital
filtering to derive real power information. This method works
accurately at any power factor (PF)
