1464493 Testing electric circuits GRUNDIG EMV 7 April 1975 [9 Aug 1974 4 Sept 1974 16 Oct 1974 7 Nov 1974] 14220/75 Heading G1U [Also in Divisions G5 and H2] A test apparatus includes a rectangular two-part housing 1, 2 a circuit board 3 carrying test circuitry with light-source indicators, and a connector element 6 and wherein one surface of the housing is apertured to permit observation of the light emitting diodes. The circuit board carrying the multiway connector 6 is located by pegs 4 and shoulders 5, is held in place by the upper part 1 of the housing and secured by a screw 18. The connector 6 which may be linear or annular, Figs. 3-6 (not shown), mates with an element (21) on a radio or television receiver, Fig. 2 (not shown), which element (21) is connected to various test points in the receiver. The light-emitting diodes indicate the acceptability of the test signals, and an indexable roller, (53), Fig. 10 (not shown) carrying test information may be viewed through an aperture (52) in the housing to provide information relative to the circuit of the receiver under test. In an alternative embodiment, a probe contact is provided on the housing for making contact with pins on a circuit board under test. Figs. 7-9 (not shown).
