6.5 Operation modes

You can carry out measurements in 3 operating modes:

• Accumulation measurement

• Carrier gas measurement

• Continuous measurement (accumulation or carrier gas)

6.5.1 Accumulation measurement

If a leaking test object that has been filled with helium under pressure is placed in a

closed measurement chamber, the helium concentration in this measurement

chamber increases over time. This is called accumulation (of helium). The difference

between the helium concentrations at 2 time points provides the leak rate.

The air in the measurement chamber must be circulated so that the concentration of

the helium in the entire measurement chamber is set equally.

The following diagram shows the typical helium concentration over time in a closed

measurement chamber with a leaking test object. Because of the helium content in the

environment, the helium value is never zero. The helium concentration shows linear

growth over time. The device measures the helium concentration in the measurement

chamber 4 times (except for turbo measurement).
