	Few devices provide any information about partial load or consumption in various states, in the manual or labels. A device's label may show the maximum power load of it, but this is likely to be only a momentary situation and may even not be ever reached in normal operation. Some devices may get to the maximum consumption only briefly in operation, such as the case of a washing machine or air conditioning device, while others draw some energy even when powered off or in standby.

	All of the above means that determining the actual cost impact of using an electrical tool or appliance is very difficult. The energy meter installed on the premise will only show the total energy being consumed and you would have to turn off all devices but your equipment, and operate for possibly a few hours in that state, to collect reliable information. This is not practical.		All of the above means that determining the actual cost impact of using an electrical tool or appliance is very difficult.

			All power load estimations are given according to European typical product ranges. Products for the American, Japanese or other markets may have highly different specifications.

	The time consideration centers around the utility of first checking quickly consumption of various common devices and then chose which more frequently used one to monitor for an hour or a day. Note that consumption estimates can vary based on use. Some modern vacuum cleaners still may have no power control.

-The most important information provided by a meter is instant power load, total electricity consumption and line voltage. The instant power load is essential as it shows as plainly as possible what amount of energy is required by a device, no matter how large or small, depending on how it is operated. As this value is clearly shown on the LCD of the meter, any doubt about the impact of device is cleared.
