Description
In "Elektronika Praktyczna" 12/2015, a project of a mini-timer was published which can be installed in a supervised device. The presented project is an extension of that idea to the possibility of measuring the time when the power consumption of the device exceeds the set value.
Recommendations: the meter can be useful, for example, to maintenance services for planning repairs of machines and devices.
