Page 9: Introduction
Corona and surface discharge are localized to small areas relative to the total size of the equipment. The Biddle Cat. No. 569001 Ultrasonic Corona and Leak Detector is equipped with a highly directional horn to permit the user to localize the source of the electrical discharge while remaining at a safe distance from the electrical terminals. - Page 10 When ultrasound is generated in parts of a container or assembly, the surfaces of the container usually transmit the ultrasonic sound but may not radiate effectively. For such cases the Cat. No. 569001-8 Contact Probe accessory is available. This probe makes direct contact with the surface to detect the ultrasound, similar to the action of a stethoscope.

Page 11: Safety Precautions
BIDDLE Instruments recommends that the loudspeaker or meter of the Cat. No. 569001 be used in preference to the headphones. The sound produced by the headphones of the Cat. No. 569001 can reach levels approaching those that risk hearing damage, therefore, the operator must set the volume control at a sufficiently low level to prevent discomfort. -

Page 15: Description And Specifications
Section D DESCRIPTION and SPECIFICATIONS GENERAL The Biddle Cat. No. 569001 Detector consists of several interconnecting components supplied in a cushioned carrying case as shown in Figure 1. The microphone probe and the receiver make up a basic complete system. The receiver converts and amplifies the ultrasonic signals from the microphone probe to an audible loudspeaker or headphone output and also to a meter deflection. - Page 16 Section D DESCRIPTION AND SPECIFICATIONS (Cont’d.) The circuit is powered from a 9-volt transistor type battery. The power requirements are small enough so that the battery life is on the order of 75 hours if used intermittently. The circuit has sufficient gain available so that the sensitivity is limited only by the noise of the input stage.

Page 19: Operation
Section E OPERATION PRELIIMINARY Select any accessories to be used with the basic system (microphone probe and receiver). Fit the microphone with either the sound concentrator or the directional horn by sliding it into the mating opening. In the case of the horn, the microphone must be fully inserted into the socket and the two thumb screws tightened with the fingers to prevent the microphone from dropping out if the horn is pointed overhead. - Page 20 Section E OPERATION (Cont’d.) If the apparatus is operating with dc, you will hear a series of popping sounds when there is an intermittent discharge. For extensive discharges the sound approaches a tone. CONTACT PROBE To use the Contact Probe, connect it to the receiver in place of the microphone. Test the system just as for the microphone except lightly rub your finger on the probe stem.

Page 21: Application
Section F APPLICATION The Corona and Leak Detector can be adapted to many different situations. In the case of large apparatus such as a small open air substation or a portion of a larger substation, use the microphone probe without the directional horn when making a fast general survey. -
