SECTION 3 OPERATION
3-1 OVERVIEW
Once the TO2 has been correctly assembled and installed in accordance with the instruc- tions in Section 2, the analyzer is ready for operation.
Before operating the system, verify that the Leak Checks have been performed in accor- dance with Section
For the remainder of this section, Analyzer Module interconnection with a Platform or some interfacing component is assumed. Dis- play and Keypad information refers to that which the user can expect to see and do with regard to the Front Panel of the Platform.
3-2 DISPLAYS & OPERATING KEYS
The LCD screen shows all measurement val- ues of the Analyzer, status values and all user menu instructions. Operation is performed with five function keys, four arrow (cursor) keys and the enter key. The function of each key varies depending on the installed Ana- lyzer module, any auxiliary modules installed, and the individual menu displayed.
In case of power failure, all user defined spe- cific module parameters are saved by a bat- tery powered memory.
The Function Keys, also called softkeys, are assigned values depending on the menu or screen being displayed. The legend is dis- played above the keys.
The Enter Key is used to confirm a previously entered variable value, to start a selected function or to go to a submenu selected at a menu line as opposed to the Function Keys. As an alternate to using the Enter Key to start a function, the → key can be used.
The Cursor Up/Down Keys (↑ or ↓) are used to move up or down the lines within a menu or to increment and decrement number vari- ables.
The Cursor Left/Right Keys (← or →) are used to move backwards or forwards between the pages of a menu or to select numeric dig- its for adjustment.
