4.4.6 Selecting an alternative mass position
When choosing a gas from the gas library a default mass position for the gas to be
detected will be chosen automatically.
In cases of cross sensitivity with other substances in your leak testing environment it
may be advisable to chose an alternative mass position for detecting the required
gas.
A list of all available gases with their default and alternative mass positions is
available in Section 9 (gas library).
The selected mass position can be changed by scrolling to the “
MASS” line item in the
“
EDIT GAS” sub-menu and pressing the “EDIT” key.
In the following display page the available different positions for the selected gas can
be scrolled with the “up” and “down” keys.
Below the selected mass it is indicated whether or not this is the preferred mass.
In addition, the mol mass of the chosen gas is stated followed by the size of the peak
relative to the largest peak for this gas.
The norm factor indicates the sensitivity for the chosen gas at its chosen mass
position.
