8.4.6 Burn-in
This function is used to prepare the detector, leaving it in optimal working condition by automatically
carrying out a series of short tests and inlet vents between each test.
NOTICE
Risk of pollution
►
Before starting this function, make sure that the leak detector is in an environment free of tracer
gas pollution.
