How should the sensor probe be moved when using an electronic leak detector?

The correct approach for moving the sensor probe of an electronic leak detector is to do so at approximately 1 inch per second. This speed allows for the most effective detection of refrigerant leaks, as it gives the detector sufficient time to sense the presence of refrigerant in the air without missing or skipping over potential leak sources.

Moving the probe too quickly may result in the detector not being able to register smaller leaks or trace amounts of refrigerant. A speed of around 1 inch per second strikes a balance, enabling the sensor to adequately sample the surrounding air for any leaking refrigerants. This method ensures that the technician can accurately determine if a leak is present, which is crucial for maintaining the efficiency of air conditioning systems and ensuring environmental safety.
