Foam filter for sensor protection. Multi-function control button for power and HIGH / LOW sensitivity selection. LED power indicator. Variable-pitch audible leak alarm. Progressive yellow LED leak indicators. Rechargeable, replaceable NiMH power stick. AC power adapter (100, 120, 230 V(ac) models available) to charge/power the instrument. 12 V(dc) vehicle adapter.
Getting Started: Installing the Sensor and Charging the Power Stick WARNING DO NOT OPERATE THIS INSTRUMENT IN THE PRESENCE OF GASOLINE, NATURAL GAS, PROPANE, OR IN OTHER COMBUSTIBLE ATMOSPHERES. The Compass Refrigerant Leak Detector is shipped with the heated diode sensor packed separately. The sensor is located in the protective foil package along with a desiccant capsule to keep it dry. Installation of the sensor in the leak detector is required before use. To install the sensor: 1.
The INFICON Compass Refrigerant Leak Detector provides similar responses to all CFC’s (e.g., R-12), HCFC's (e.g., R-22), HFC's and refrigerant blends (e.g., R-134A, R-404A, R407C, R-410A) as well as SF6. There is no need to change settings for the refrigerant you're working with. The Compass has two sensitivity settings: HIGH and LOW. The sensitivity indicators are located on the upper right hand face of the instrument. LOW is eight (8) times less sensitive than HIGH sensitivity.
Choosing Power Options The INFICON Compass Refrigerant Leak Detector will operate with a charged power stick or by connection to the AC power adapter. When the instrument is plugged in using the AC power adapter, the power stick will continue to be charged while the Compass is operating, although more slowly than if the instrument is off. A 12 V(dc) power cord is also included, designed to charge and power the Compass from your vehicle's cigarette lighter.
Changing the Sensor The Compass's electrochemical heated diode sensor is located in the tip of the probe. This specialized sensor will operate for about 100 hours. When that amount of time has passed, or you feel you may have missed some refrigerant leaks, you should replace the sensor. A reference refrigerant leak is also available separately from INFICON to check your sensor's sensitivity. (See Replacement Parts and Accessories.) To change the sensor: 1. Turn off the leak detector. 2.
Troubleshooting NOTE: The internal parts of the Compass Leak Detector are not serviceable. Do not attempt to disassemble the instrument, except for replacing the filters, sensor or power stick. Opening the plastic housing for any reason will void the warranty. Problem Cause Remedy 1. Green ON light flashes but detector still runs. 1. Power stick voltage is low. 1. Finish current job and recharge power stick, or be prepared to plug in AC adapter to power leak detector. 2.
Problem Cause Remedy 6. Leak detector is not very sensitive, seems to have missed leaks, or picks up some refrigerant types but not others. 6. Sensor has reached the end of its useful life. 6. Purchase new sensor from distributor and install in Compass. If you require additional assistance, please call 1-800-344-3304. Replacement Parts and Accessories Replacement parts and accessories for your Compass are available through the same dealer from whom you bought the instrument. Replacement Power Stick.
Warranty and Liability-Limitation INFICON warrants your Compass Refrigerant Leak Detector to be free from defects of materials or workmanship for two years from the date of purchase. INFICON does not warrant items that deteriorate under normal use, including power stick, sensor and filters.
