ABSTRACT:
A test device includes a pair of test probes (21 and 22) which are manipulated onto a succession of test sites (11, 13 and 16) formed on a complex circuit board, and the operator is visually apprised of test results without loss of eye contact with the test sites. Visual appraisal is provided by a small light emitting diode (46) which is activated in accordance with the probed test results. The diode is mounted on the operator's safety glasses (58) and is of such size as to be not discernible when positioned inside the normal focal point of the operator's eye, but a glow is discernible when the diode is operated upon a particular test condition being ascertained by the test probes.
