Maintain Menu
Access to the fields in the “Maintain” menu is restricted. Data can displayed, but changes and de-
letions are only possible after entering the maintenance password [or higher] or operating a key
switch.
Calibration Submenu
To calibrate the individual gas detection inputs a manual 2-point calibration procedure can be
used and if required an automatic presetting can be done during the first calibration. After a cali-
bration process has been started using the MDO, ‘Zero’ gas must be applied to the sensing head.
Then a ‘Test’ [span] gas must be applied. The results of a calibration are then displayed and saved
[see section 7.1 Maintenance and Adjustment].
NOTE: The presetting is applied immediately and cannot be cancelled or discarded.
Calibration parameters for the individual inputs can be set in the calibration menu. From that point
on the calibration is controlled by the SUPREMATouch.
The window is divided into two subwindows:
- “Start calibration”
- “End calibration”
If an input is selected that is not already in calibration mode, the “Start calibration” window ap-
pears. If an input is selected that is already in calibration mode, the “End calibration” window ap-
pears.
The functions of the individual fields are described below.
The “Meas. Point” and “Tag” fields are contained in both subwindows.
Meas. Point
Field type: Selection
The field contains a list of all configured inputs. After an input number is selected, the rest of the
fields are filled, depending on whether or not the input is in calibration mode.
Global parameter changes and actions using the fields described below apply to the in-
put selected in this field.
