When refrigerant is detected, the buzzer will change to a "siren" type sound.
Verify the place of siren and detect continuously until the leak is confirmed.
Operating
Adjust to the higher sensitivity, when a leak can't be found. Adjust to the lower
sensitivity when unstable.
When the buzzer alarms for leak, if the sensing tip remained at the part being
detected long enough,the circuit will equalize
