Overview
From very low power to high power, applies to the wide range of power measurements!!
The KPM1000 Digital Power Meter is a single-phase power measuring instrument that applies to the wide range of power measurements, from very low power during standby mode to high power during operation mode. It has a minimum power range of 750 mW, with resolution of 0.01 mW, and the basic accuracy of 0.1% of reading with guaranteed accuracy extending from 1% of the range while it realizes a wide dynamic range.
In recent years, eco-design regulations have been actively implemented in many countries, starting with Europe’s ErP Directive and including the United States’ Energy Star and Japan’s Top Runner Program. These regulations are being utilized by companies in their efforts to act against environmental problems and differentiate their products. Through ErP Directive Lot 6, the standby power (off mode and standby mode power consumption) of household electrical appliances and OA electronic equipment is regulated and the preparation of a declaration of conformity is required by CE marking. This requirement regulates the standby power to become 1 W or less; and starting in 2013, the regulation will be strictly reduced to 0.5 W or less. The KPM1000 can accurately measure the standby power even less than 0.5 W.
The KPM1000 complies with IEC62301 (the measurement of standby and off mode power in household and office electrical and electronic equipment products) standards, and it is capable to perform the standby power measurements required by ErP Directive Lot 6 and other regulations. System upgrades are also possible. Because of its size, weight, and various type of optional interface (some are factory options), the KPM1000 can be widely used as a beach-top instrument for measuring equipment power and also as a part of component of the test system.

Power measurement and application examples
Measurement with direct input (Less than 20 A of DUT)
Measurement using CT (current transformer) and PT (potential transformer) (Exceeds 20 A of DUT)
Measurement of standby power
Measurements complying with IEC62301 First Edition standards can be performed. It is possible to measure the “standby and off mode power” of the household and office electrical and electronic equipment products required by the standard such as ErP Directive Lot 6.
Utilization of Assist Tool
A handy application software Assist Tool can be downloaded from the WEB. It makes the operation possible from a PC as you would from the main unit panel. And as a data logger, it can easily acquire the long term periods of data, too.
Collective display of measurement parameters
17 measurement items can be displayed in a single window.
Measurement data logging feature
Using the Assist Tool, you can import waveform data to the PC in the CSV format with a simple connection and a single press of a button. When an application such as Excel is used, graphs can easily be created.
Acquisition of voltage and current waveform data
You can easily import voltage and current waveforms to a PC. It is difficult to imagine what type of waveform they actually have even when the peak values, crest factors, and power factor values are viewed. Also, it is difficult to use and take measurements with an instrument such as an oscilloscope with linear measurements of surroundings. With this function, voltage and current waveform data can easily be imported to a PC in the CSV format. When an application such as Excel is used, graphs can easily be created.
