Testing For a Gas Leak  
1. Turn instrument ON and allow it to warm up (approximately 60 seconds).  
2. The instrument is ready to check for gas leaks after the audible alarm begins to  
beep. Note that the instrument starts in its high-sensitivity mode.  
3. Check for the presence of gas by positioning the tip of the flexible probe near the  
area to be tested.  
4. An increase in the relative concentration of gas is indicated by the visual alarm’s  
LED blinking faster and the audible alarm’s beep rate increasing.  
5. Once the presence of the gas has been confirmed, the instrument’s sensitivity  
can be lowered by double pressing the ON/OFF button (a decreasing frequency  
tone should be heard), allowing the location of the leak to be easily pinpointed.
