What is the maximum linear rate for operating a low voltage holiday detector?

The maximum linear rate for operating a low voltage holiday detector is established at 1 ft/s. This specific rate is important for maintaining the accuracy and reliability of the detection process. Holiday detectors are used to identify discontinuities in coating films that could lead to corrosion if not addressed. At a speed of 1 ft/s, the device can effectively scan the surface while ensuring that the inspection current has adequate time to assess the integrity of the coating, allowing for a thorough examination of the areas being tested.

Exceeding this speed can result in missed holidays or incomplete detection, as the device may not have the necessary time to register all the fluctuations in the coating's integrity. Thus, operating the detector at or below this recommended rate ensures that the inspection is both efficient and comprehensive, ultimately contributing to the long-term performance of the coated surface.
