A hard vacuum test can be performed as soon as one of the test
modes is reached
The leak detector will automatically switch to the selected mode as
soon as the inlet pressure has crossed the threshold.

Use the correction factor to work in a unit other one than those
proposed (See board
G 700 for the factor to be applied) or with
an installation having its own pumping.
According to the He concentration level in the gas used for the
leak detection, the displayed signal changes.

By default, the leak detector is configurated to work in vacuum
test, in the most sensitive test mode: this configuration meet the
majority of the operators needs.
