Page 10: Low Battery Indication
Operation The Informant Refrigerant Leak Detector Low Battery Indication A low-battery condition is indicated when the LO BATT LED glows. There will be approximately 20 minutes of full operation time remaining from the time this LED fi rst turns on; after which, the intensity of all LED’s and audible output will gradually diminish. -
Page 11: Procedure For Locating A Refrigerant Leak
The Informant Refrigerant Leak Detector Operation sensitivity mode helps locate a refrigerant leak source when the leak is large, or where high winds may affect the instrument’s operation. Place the Informant into its low-sensitivity mode by pressing and holding down the LOW SENS / MUTE button until the LOW SENS LED turns on. Return the instrument to its normal-sensitivity mode by again pressing and holding down the LOW SENS / MUTE button until the LOW SENS LED turns off. -
Page 12: Sensor Failure Indication
Operation The Informant Refrigerant Leak Detector which, if the probe is moved away from the leak source, the detector will respond with a lower refrigerant level indication. Caution: Exposing the sensor to a steady stream of highly concentrated refrigerant will severely reduce sensor life or damage the sensor. -
Page 13: Sensor Flooding Indication
The Informant Refrigerant Leak Detector Operation Sensor Flooding Indication When the sensor becomes fl ooded with a high concentration of refrigerant, observe that the gas-level LED’s quickly light full scale and then all turn off, leaving both the audible tick rate and probe tip blink rate at elevated levels. - Page 14 Operation The Informant Refrigerant Leak Detector • At each area checked, the probe shall be moved around the location, at a rate no more than 25 to 50 mm/sec (1 to 2 in./sec), and no more than 5 mm (0.2 inch) from the surface completely around the position. Slower and closer movement of the probe greatly improves the likelihood of fi...
