NOTE: In extreme cases, such as when the sensor is exposed 
to moisture, warmup can take up to 20 minutes.
4.  Using TEK-Mate to detect leaks
a. Place the tip of TEK-Mate as close as possible to suspected 
leak (do not block air flow).
b. Slowly move the probe past each possible leak point.  If a leak is 
detected, TEK-Mate will alarm and the HIGH or LOW indicator 
will flash.  Faster flashing and alarm indicate a higher 
concentration of refrigerant.
c. When a leak is identified, pull the probe away from the leak for a 
few seconds and return to the suspected leak site.
NOTE: For large leaks, press the power button to switch to low 
sensitivity mode.  The LOW indicator will flash when 
low sensitivity mode is active.
5.  Replacing filters
a. Remove dirty or clogged filter with a paper clip or similar object.
b. Push the new filter into the probe tip.
