A channel (500) is configured and arranged to be fixedly mounted (401) to equipment (100) to be temporarily monitored. At least one sensor-engagement member (80 0) is movably captivated (402) within this channel and a sensor assembly (1000) (comprisin g a plurality of photosensitive receptors (1001) that are disposed in a pattern that corresponds to signal lights as comprise a part of the monitored equipment) is biased (404) towards the sensor--engagement member by an affixment member (1200) to thereby retain the sensor assembly i n place with respect to the monitored equipment. By this approach, the sensor assembly (in combination with the sensor-engagement member) can be moved (403) along the channel to a selected position with respect to at least one of the signals lights and the n retained in that selected position by the affixment member. |
