- c: D+ d; Y* {Standard CISPR 14-1 is applicable for the measurement of clicks produced by a lighting chain equipped with an electronic control box that changes the cadence of the light.
The standard does not give any information concerning the test set-up for this kind of equipment. It does not give the layout of the lighting parts such as winding up, folded back and forth parallel to the lead so as to form a horizontal bundle for a power supply cable exceeding a length of 1m or fully uncoiled. As a result the tests can conducted with different results.
/ f  v( `/ v' ~& ZTo put in place the lighting chain fully uncoiled is not realistic due to the length of the lighting chain (from 3 m until 30 m)
Decision:
4 D1 k. {+ q, Q% EThe correct test set-up for measurement of voltage disturbances on mains port of lighting chains” (continuous or discontinuous disturbances) is as follows:
1) Distance between AMN and electronic control box according to the rules of CISPR 15 (0,8 m +/- 20%). If the power supply cord is longer than 0,8 m, the cord is folded back and forth in the shape of a meander, as far as possible so as to form a bundle not exceeding 30 – 40 cm in length.
, Q/ c5 e+ p& s) t2) The lighting chain itself should be extended behind the electronic control box up to a length of 1m and bundled in order not to exceed this additional 1m. The total length of the test arrangement will be about 1,8 m.
