Description
Changing this value changes the position of the
green trip level indicator in the analyser vacuum
display.
The function shuts off all analyser and source
voltages if tripped and protects the instrument
against pressure surges. Set a value of about 5.5,
which corresponds to about 3e-6 mbar.
The speed at which the source turbo operates.
When the source is pumped down (evacuated) the
value should be between 95 and 100%. A value
below 90% indicates a cooling fault.
