Answer :
Final answer:
Technician A and Technician B are both partially correct. The electronic leak detector probe should be held directly against a suspected leak area, and routine calibration and inspection are necessary for the detector to function accurately.
Explanation:
Technician A and Technician B are both partially correct. When using an electronic leak detector probe, Technician A is correct that the probe should be held directly against a suspected leak area during a leak test. This allows the detector to accurately detect any traces of refrigerant or other gases indicating a leak. Technician B is also correct that routine calibration and probe tip inspection and maintenance are necessary for the proper functioning of the electronic leak detector. Since the detector relies on accurate measurements, regular calibration and inspection ensure its accuracy and reliability.
