Reference is made to the circuitry enclosed by the broken line labeled "Multi-Circuit Current Sensor". T10 and T11 form a differential pair. T9 with its base connected to voltage source VA forms a high current limiter. T12 and resistor R5 provide a current sink. T12 is turned on by the collector current of T10. Current sense indicator IS is connected to the collector of T12.
