Voltammeter ВА-240 is designed to measure voltage and current in the electrical network. The wires are connected to the shunt and to the diesel wiring circuit according to the diagram. The magneto-electric mechanism is covered with a dial on which there are scales with two rows of digits: the upper row of digits from 0 to 30 for voltage readings, the lower one from 0 to 60 in one direction and from 0 to 20 in the other - for current readings. voltampermeter.
