NOTE 8—This type of location is commonly used in leak location due to the presence of continuous emission. AE signal end—the recognized termination of an AE signal, usually de? NOTE 5— Use of the term continuous emission is recommended only for describing the qualitative appearance of emission signals.

One candela produces 1 lumen of luminous? By monitoring the AE signal magnitudes of the continuous signal at various points along the object, the source can be determined based on the highest magnitude or by interpolation or extrapolation of multiple readings. The common types are as follows: Also called halogen-sensitive leak detector or halide leak detector.
