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.
NOTE: The detector will NOT operate without the power stick installed.
Recharging the Power Stick
A fully charged power stick should provide power for greater than 5 hours of continuous
operation.
Š When the power stick voltage is low, the green ON indicator will flash and you will have
adequate power to use the Compass for a short time.
Š When the power stick is fully depleted, the Compass will shut down and the green ON
indicator and highest yellow leak indicator LED will flash in an alternating manner.
Recharge the Compass by connecting it to the supplied AC power adapter, or by using the
cigarette lighter adapter. Allow 10 hours for a full charge.
NOTE: The power stick does not need to be fully charged to operate nor fully discharged
before recharging.
WARNING WARNING WARNING
DO NOT ATTACH ANY OTHER POWER CORDS TO THE COMPASS POWER
JACK EXCEPT THE AC POWER ADAPTER AND DC CORDS DESIGNED FOR
THIS INSTRUMENT.
Changing the Filter
The foam filter in the probe tip should be replaced if it becomes plugged with water or oil or
appears dirty. To replace the filter, twist off the tip protector (counter clockwise) and simply push
out (with a paper clip or similar object) the filter from the sensor side (larger end) of the tip
protector. Slide the new filter into the small hole in the tip protector, then replace the tip
protector. If the sensor becomes unseated when you remove the tip protector, take it out and
plug it back in, as described in the next section.
