A “click” is defined as a disturbance exceeding the limit of continuous noise for not longer than 200ms, separated from a subsequent or preceding disturbance by at least 200ms.

All the automatic, programme-controlled machines, electrically-operated and thermal appliances, generate clicks.
The effects of such disturbance, vary with the repetition rate and the amplitude: the higher is the disturbance amplitude, the lower should be its frequency of occurrence.

AFJ CL55C have been specially designed to fully support a thorough investigation on the when, where and why a click occurs.

CL55C provide for a very substantial contribution to problem-solving requirements, in a critical domain of equipment compliance.
