              Used by the International Energy Agency (IEA) during the energy management workshop on the network among IoT devices,

              this product features excellent power measurement functions, particularly, active/standby power consumption pattern analysis,

              and presents ways to save energy by measuring and monitoring a variety of power related parameters,

              including active/standby power consumption of electric appliances that are unnecessarily wasting electricity,

              electric charges based on monthly and annual power consumption based on pattern analysis, and carbon emissions.

              With the adoption of a plug & play method, it allows you to view four major power measurement items

 simultaneously upon plugging into a universal multi-tap.

 The use of the data logging function and GUI program will facilitate the preparation of power consumption pattern analysis

 and verification reports.



Gui Program and RS22 communication compatible

Embedded Data Logger: (optional) data may be saved using internal memory instead of external USB or SD card

Precise measurements of low power and low powerfactors

Time settings when making measurements of wattage

Easy plug & play measurements  

Excellent readability of LCD and simultaneous measurements of four items, including V, A, W and Hz

Switch between two different types of electric charge (domestic, industrial)

Compliance with KS C IEC 62301 Standard for standby power measurements

Acquired Performance Certification, World Class Product certificate, Procurement Excellence certificate, CE, FCC certificate

Performance accredited by the international testing agency “Interteck” based in UK

Selected by the official wattage of the “SELINA Project” in Europe

Invited for demonstration at the International Standby Power Conference in Australia, India, and Japan

Participated in the Standby Korea 2010 National Roadmap Project

 1. Upon applying the power supply, plug the source device

into the multi-tap on the bottom right corner.

2. Push the Display button to change the mode to Watt hour (Wh).


3. Push the Wh TIME SET button to set the saving time

(00 through 24 hours)



4. Measuring of the watt hour (Wh)

begins upon pushing the Wh RUN/STOP button.


5. “Energy” will be displayed in the top right corner

of the screen and measuring of the watt hour (Wh) begins.


6. Upon completion of watt hour integration calculation,

push the Display button to change the mode to CO2 emissions.


7. Check the CO2 emissions in association with the watt hours measured.


8. Push the DISPLAY button to change the mode to electric charge.


9. If you want to measure the power of another device,
push and hold the Wh CLR button for three seconds
to initialize the data and repeat the measurement.



            (view electric charges and carbon emissions)

      This is available in the measurement of standby power and constant consumption power.

Push the HOLD button in the effective power display mode and push the DISPLAY button.

             Next, the estimated electricity consumption, electric charges, and CO2 emissions will be displayed

on a monthly and annual basis as illustrated below.



            (various power analysis functions)

            The Wattman offers two power data collection and analysis functions: PC program-based and Data logger-based.

            Functional enhancement along with new functions added

            Integrated change from HPM-100 Viewer to “Wattman Viewer”

            (compatible with the existing viewer dependent upon product settings)

            A variety of improvements have been made, including enhanced reliability against exceptions

            such as communication error while collecting data,

            display of data collection time, and promoting ease of use such as introduction of icons.

            New functions are offered, including wattage control button, discrete mode (individual collection mode)

            Real Time Graph & All Data Table with Statistic

            Display of dedicated graphs for data collected on a real time basis,

            and statistical values such as real time data table, minimum, maximum, average, CO2 emissions, and estimated monthly values.

            Data Table adopts the All Data Table method to display all collected data.


            Data collection environment settings and automatic file saving

            You may configure a variety of data collection parameters,

including collection interval, file name, total collection time, unit, C)2, and electric charge.

            Upon completion of collection, you may automatically save it with a preset file name in a format compatible

with Microsoft Excel.


            File Statistic & Graph Analysis

            This opens a file and displays minimum, maximum, average, CO2 emissions, and estimated monthly values on the data table.

     It also draws graphs for V, I, W, Wh, PF, Hz, and cost data.

You may move and resize the graphs, facilitating quick and precise interpretations, and report preparation as well.









A rapid industrial development is usually accompanied by an increase in CO2,

environmental contamination and global warming at an alarming rate.

Furthermore, the nuclear disaster in Fukushima, Japan necessitates energy savings.

Energy savings is referred to as the fifth energy.

All stakeholders, including government,

local autonomous bodies and people should actively engage in the energy saving campaign.

Domestic Usage


Oversea Usage - Celina Project

Supermarkets in various European countries measure active/standby power consumption

using the Wattman, and use the data to come up with appropriate energy policies.


Oversea Usage - IEA Subsidiary Agencies

Wattman has been invited to demonstrate its functions and usage in the International Standby Power Conference.


Oversea Usage - IEA International Workshop

Wattman has been used in the IEA International Workshop to show
