<p>The indicator circuit is for connection to the first, second and third phases of the meter. The third phase is connected to a second node point via a first resistor. The second phase is connected to a third node point which is connected to a first node via a third resistor and to the second node via a second resistor. The first phase is connected to the first node via a capacitor. The first and second nodes are connected to a display member.</p> |
