In the Review menu, navigate to the Additional Status option� Plug the inlet
tube� If the system is not leaking, the detector will display a fault after about 30
seconds� This may take longer if the sampling wand is attached and possibly as
long as 2 minutes if the test gas must travel through a lengthy sample tube�
If a fault is not issued, observe the flow reading on the detector’s display� If it
stabilizes at more than the maximum rate shown in the “Sample Analysis Flow
Rate” column of “Detectable Gases” on page 62, there is likely a system leak�
