To perform refrigerant leak detection follow the instructions below 12 0019 9372 Rev 0 Tru Pointe IR Refrigerant Leak Detector Leak Detection Procedure that the instrument s battery is fully charged before initial use Charging takes approximately 3 hours Press and hold the ON OFF button for one second to turn on the instrument Wait for the warm up and calibration sequence to complete This takes approximately 30 seconds The default sensitivity level is High at startup Change this setting using the L M H button based on your preference and application If you suspect a large leak use either the medium or high sensitivity setting Locate the most likely place for a refrigerant leak Key points to consider include e soldered joints in refrigerant lines e points that have changes in cross section e points that have changes in direction of these lines Visually trace the entire refrigerant system all lines hoses fittings couplings service valves etc looking for signs of lubricant leakage damage and corrosion as indications of likely leak points Move the probe slowly approximately 3 in sec or 75 mm sec ina sweeping back and forth motion no more than 0 25 0 63 cm away from suspected leak areas See Figure 7 Acloser probe position and slower sweeping movement normally improve the likelihood of finding a leak The audio signal will increase in the number of tics per second in proportion to the detect

5. e and particular application Consecutive presses of the L M H button will toggle the instrument through these three modes A NOTE Generally a retest is advisable when a leak is discovered using the most sensitive settings or if the probe was in a static position when the leak was discovered In these cases repeat the test ensuring the probe moves past the suspected leak location while maintaining the smallest possible gap between the suspected leak point and the tip of the probe Also consider using the Medium sensitivity position of the detector after finding an apparent leak with the High sensitivity setting A fourth sensitivity setting is Background Mode Background Mode is the most sensitive operating mode of the Tru Pointe IR In this mode the instrument will trigger on extremely small refrigerant levels as well as sudden probe movements e With the instrument in High sensitivity mode quickly press the Peak button 4 times in succession to put the Tru Pointe IR into Background Mode e The first left most LED in the bar graph display will blink quickly when in Background Mode e The leak detection tone will change from a tick to a steady tone when in Background Mode e To exit the Background Mode quickly press the PEAK button 4 times in succession or switch from High sensitivity mode to one of the other levels 0019 9372 Rev 0 11 Tru Pointe IR Refrigerant Leak Detector 2 5 Probe Selection The Tru Pointe IR has
