Operation

4 Operation

The AccuMind R© is operated via the touch screen display. The Ac-cuMind offers five different screen modes which can be switchedbetween with the arrow buttons in the bottom line (see Figure 4).Different screen modes are available with one up to six fields to dis-play measurement readings and calculation results.

Figure 6: Basic display with process parameters. The display can bechanged with the arrow buttons. Touching a field will open a menuto select different process parameters and may trigger a passwordrequest! (→ 4.2))4.1 Selection of the shown Process Parameters

To switch between displayed process parameter the correspondingfield on the display has to be touched. The AccuMind will then askfor a passwor(→ 4.2).The available process parameters are depending on the entered pass-word and the corresponding access level.A variation of process parameters are selectable. Depending on thenumber of parameters the selection has to be divided into severaldisplays with nine parameters each. To switch between displaysplease use the arrow buttons.Once a parameter has been selected the appropriate measurementunit has to be selected. If the variable has been selected before theaccording unit is stored and can be changed later through the menu(configuration→ units→ selection of units (5.2.7)). Finally the num-ber of decimal digits can be selected. If the Enter button is pressedor 0 is entered the process parameter will be shown as a whole num-ber.

4.2 Password access

The AccuMind R© is protected against unauthorized accress througha hierarchic password system. Profound changes in the system canonly be executed by authorized personnel. Simple changes (e.g.change of displayed process parameter) can be executed by the stan-dard user.

10

The password menu is shown in figure 4.2. When a valid password isbeing entered and confirmed through touching the ’ENTER’ button asub-menu will open which is associated to the user rights connectedto the entered password. ’DEL’ will delete wrong input and ’CANCEL’will leave the password menu.

Figure 7: Password input menu.The following passwords are being stored in factory default:Level Factory Default User Setting1. Operating staff 56982. User 89563. Service 89144. Parameterization 64575. Lab 89726. OEM7. SKI intern8. SKI Development9. MasterThese passwords can be changed through themenu via→ Access→Change PWD. For amore detailed explanation please refer to section5.2.8).

4.3 Tool symbol button

Touching the tool symbol buttonwill open amenuwhich allows chang-ing all settings. This menu is password protected. All settings aredescribed in the next menu point under → 5. For the simple flowmeasurement operation this button is not required.4.4 Bread crumb navigation

The bread crumb navigation allows simple and fast solving of prob-lems. If a problem occurs which can be solved through a differentsetting in the menu system amessage is shown in the top row of thedisplay. Touching this message will redirect the user to the appropri-ate sub menu and allows to change the user the setting.The company symbol in the upper right corner serves as an ’EXIT ’button for fast navigation and will change the display to the last usedbasic operational display.
