ELECTRICITY METER

摘要

An electricity meter is provided which is capable of communicating assessment results as to whether integral power consumption is expected to exceed a target value, even to users who do not intentionally attempt to verify their power consumption. A calculation unit 9 is provided with a target setting means 22 for setting the target integral power consumption for a predetermined period of time, and an assessing means 23 which, on the basis of the current integral power consumption and the target integral power consumption, makes a judgment of a warning state in which the integral power consumption at the end of the predetermined period is expected to exceed the target integral power consumption, or a non-warning state in which the former is not expected to exceed the latter. A display block 3 is distinctly provided with a light-emitting display unit 20 comprising LEDs which continuously emit light, as a separate unit from a power consumption display 10, and the assessment results of the assessing means 23 as to whether the integral power consumption is expected to exceed a target integral power consumption are continuously notified by means of the light emitting state of the light-emitting display unit 20.
