Electronic Leak Testing

CAUTION: CARE SHOULD BE TAKEN TO PREVENT PERSONAL INJURY WHICH COULD OCCUR DUE TO TOUCHING A HOT ENGINE WHEN TESTING. TESTS SHOULD BE DONE WITH THE ENGINE OFF AND AS COOL AS POSSIBLE. DO NOT OPERATE THE DETECTOR IN A COMBUSTIBLE ATMOSPHERE SINCE ITS SENSOR OPERATES AT A HIGH TEMPERATURE.




The successful use of this and any other electronic leak detector depends greatly upon the scan rate and carefully following the manufacturer's instructions regarding calibration, operation and maintenance. Each joint, including soldered, brazed and welded areas, must be circled moving at 25 - 30 mm (1 - 2 in.) per second with the tip of the probe as close to the surface as possible. The tip should be no more than 6.35 mm (1/4 in.) away and must not block air intake. A leak is indicated when the audible tone goes from a steady one to two clicks per second to a solid alarm.
