Abstract

1520650 Testing electrical apparatus STANDARD TELEPHONES & CABLES Ltd 16 Oct 1975 42443/75 Heading G1U To test voltages in, e.g. a television receiver, a number of light-emitting devices (e.g. diodes) are connected via suitable impedances if necessary to test points, the devices providing a visible indication of satisfactory, or otherwise, voltages at those points. A fault finding diagnosis chart may be provided to identify faults given particular patterns of lit or unlit l.e.d.s.
