System TC being at atmosphere is not a normal state for
the leak detector. The turbo pump must be turned off,
and the spectrometer tube must be vented by operating
the valves or by opening the vent screw on the turbo
pump. This is best done before the pump gets up to
speed just after turning the leak detector on.
You must take care to avoid damage to the vacuum
system and the spectrometer tube. Follow instructions
carefully.
