4.4.1 Editing gas parameters
When pressing one of the “
GAS
1” to “
GAS
4” buttons an info page regarding the
corresponding gas will open.
Changes to the current settings can be made by scrolling to the line item to be
changed by use of the “up” and “down” keys and selecting the highlighted line item
by pressing the “
EDIT
” key.
In the opening info page the name of the gas, the currently selected trigger value and
the measurement mode will be displayed. This info is followed by the value for the
lower display limit and search level and the status of the internal calibration. In
addition, the currently selected mass position, the calibration factor for the chosen
gas, the date of the last calibration and type of the last calibration are listed.
Gases with mass positions between 40 and 105 amu may be calibrated via the built-
in ECO-Check reference leak. If a gas may be calibrated with the ECO-Check
reference leak the line item „Internal cal“ will show “enabled”. If “disabled” is stated
the selected gas is not set up to be calibrated internally but must be calibrated via an
external test leak.
If the chosen gas can not be calibrated with the ECO-Check reference leak (because
its mass position is below 40 amu or above 105 amu) this line will state “impossible”.
For details on how to perform an internal calibration see Section
3.5.2 .
4.4.2 Removing / adding a working gas
A selected gas can be removed from the main display by setting the
MODE
in the
GAS
EDIT
menu to “disabled”. If you want a gas to be included in the list of measured gases
again, please set the Mode back to “enabled”.
When choosing the “
NAME
” line of the info page and pressing “
EDIT
” the gas library
will open and a new gas can be selected from the list of pre-programmed gases.
You can scroll through the list by the “up” and “down” keys. For faster access also
scrolling through the columns of the list is possible by the “left” and “right” keys.
The currently highlighted gas is selected by pressing the “
OK
” button. The menu can
be exited without changes by the use of “
ESC
” button.
