After the instrument is turned ON and allowed to warm up, observe that both the leak rate LED and the audible indicator should be flashing/ticking at no more than 1 or 2 times a second, indicating that the instrument is in its idle state and currently not detecting an increasing concentration of refrigerant.
Important: The instrument’s function is to detect a change in refrigerant level, and not to make a quantitative measurements. The technique of locating a leak by detecting a change in level allows an operator to quickly locate the source of a leak without making manual sensitivity adjustments, or being concerned about the background refrigerant level in the surrounding area.
Begin by slowly moving the probe tip toward the area of the suspected leak source. If surfaces are dirty or wet, wipe them off with a shop towel. Avoid allowing dirt to clog the probe tip, or allowing water to enter the instrument. When the instrument first detects an increase in the refrigerant level, the leak rate LED begins flashing and the audible indicator begins ticking at a faster rate. If movement of the probe is stopped for more than 10 seconds, the instrument will self-zero and return to its idle state even though refrigerant is still present.
