Display limit (and
search threshold)
In the “Search threshold display limit” window, you can set the search threshold with
the buttons on the left and select the factor for the lower display limit with the buttons
on the right.
The search threshold is a percentage of the trigger value and serves as an additional
warning level. Smaller leaks that are even below the trigger value can thus also be
reported when needed, see "Audio settings [}34]."
The absolute value of the search threshold is calculated by the device and displayed.
Fig.23: Setting display limit and search threshold
With the “Display limit” function, you can hide measurement results that are below the
expected leak rate. This makes the measurement view clearer especially in view of
the measurement bar because smaller measurement results are hidden.
You can define the lower display limit as a multiple of the lowest measurable leak rate
(1 x, 2 x, 5 x, 10 x, 20 x, 50 x, 100 x).
Internal calibration You can deactivate internal calibration. If it is deactivated, only the more precise
external calibration can be carried out for the gas, see "Calibrate [}43]."
Internal calibration is precluded from the start if the mass position of a gas is outside
the range from 40 to 105amu.
Mass With the selection of a gas from the gas library, a standard mass position is
automatically selected for gas to be measured. If the device could respond to other
substances in the working environment for the leak detection, we recommend
selecting another mass position for the verification of the required gas. You can find a
list of all possible gases with their normal and alternative mass positions in the
Appendix, see "Gas library [}87]."
