The indicator works as a part of electrical equipment of road construction equipment with a rated voltage of the on-board network of both 12V and 24V, as well as an operating time counter in industrial electrical installations with a constant voltage supply from 9 to 36V. The required operating mode is determined by the pointer switching circuit. It can operate in the hour meter / voltmeter mode, in which the indicator constantly displays the voltage of the on-board network, and the operating time is counted only when the engine is running, and in the operating time counter mode, in which the operating time is counted and displayed continuously when the supply voltage is present. In the operating hours / voltmeter mode, the indicator also monitors the voltage of the on-board network (voltage on the battery) and signals by flashing the symbol when it goes beyond the permissible limits.
