STEPS/TIPS ON USE: (see video on this page) -To detect leaks while minimizing false alarms, turn the sensitivity dial upward toward (+) until the device begins to alarm away from any gas leak. Turn sensitivity dial downward (-) slightly until alarm stops and 1st LED just turns off. Now, any small increase of gas level (as from a leak!) will cause the alarm to sound. -If alarm sounds prematurely, sensitivity needs to be decreased to prevent false alarms. -Each leak varies in leak rate and background gas concentration, so adjust sensitivity level to find any leak. -Allow device to warm up sensor for 10s until yellow “Warm Up” light turns off.
