All text in capital letters refers to keyboard selections. For example, press the ENTER key. 

With the LS-5B instrument, the printing of the sample photomultiplier can be delayed so that it no longer coincides with the flash. When used in this mode, the instrument measures phosphorescence signals. Both the delay of the start of the gate (tA) and the duration of the gate (t ) can be selected in multiples of lOps from the keyboard. Delay times may be accurately measured, by varying the delay time and noting the intensity at each value. 

The computer, which conPols the Stainer, is an integral part of the unit. Programming is performed using a restticted set of buttons (not a full keyboard), and menu selections are displayed on an LCD screen. The slides are individually pro-... 

However, if you still cannot see the Start menu, you have three more options. (1) You can press the P=- key on the keyboard or type CTRL-ESC. These keys will bring the Start menu to the top and also select the Start button. (2) If you... 

Press the W key. This is the keyboard shortcut for selecting Place and then Wire from the menus. 

Throughout the manual many keyboard sequences are given as shortcuts for making menu selections. The explanation of these sequences will be given later. It is important to know the conventions used to specify the sequences. 

Click this button to exit from the current button panel mode, and return to the display ground state of the spectrum window from which another function with its own button panel mode may be chosen. Selecting an entry from the pull-down menu bar in the main menu automatically causes a change in the display ground state of the spectrum window. The Return key on the keyboard has the same function. 

Keyboard for input of analytical parameters and operator-selected variables. 

The generation of frequency sweeps under computer control, described in Section II, 3 (p. 13) is one small aspect of a general tendency towards control of analytical instrumentation by means of digital computers, through appropriate interfacing devices. Several commercial and individually built systems have appeared in which all of the instrumental parameters for frequency sweeps or pulse-excitation (see Section IV, p. 45) are selected by teletype or numerical keyboard input to the computer, which then acquires the spectral data automatically and performs any further processing required. Automatic analysis of spectral peak positions and areas by a computer, and printing of the numerical results on a teletype or... 

Signals from the image received by the camera are processed by a central processing unit that contains circuits for measuring areas of features, number counts and size distributions based on selected diameters. Parameters such as ratio of maximum to minimum diameters may also be determined. The area under examination is displayed on a screen and interaction is either via a teletype keyboard or menu driven. Using this unit, objects can be selected for examination, objects can be deleted and touching particles can be separated. 

Microprocessor-based control strategies like this one generally include a selectable temperature-setpoint profile that is based on product grade. In other words, the operator can push a button or select from the keyboard the desired temperature profile. A setpoint-generator algorithm then continuously calculates the setpoint as a function of time and feeds it to the controller. The controller, then, controls to this setpoint. 

Figure 1.1 Screen dumps of the EXPLORER trees for the files on the GT Calculator CDROM. Each file is activated by selecting the particular icon of the tree and then activating with the mouse or by pressing the ENTER button on the keyboard.

Eor example, to operate the GT Calculator for the case of structures of Ih symmetry, select Ih.xls and open this spreadsheet in the usual manner, either by pressing the ENTER button on your keyboard or with your mouse. The initial screen display will be as in the first diagram in Eigure 1.2 and it is necessary to choose the enable macros option in order to activate the functionality of the calculator. After a short graphic display, which can be cancelled with the ESC button, the standard logo screen for the calculator files is displayed with the centre text used to distinguish the different point groups. 

An Excel worksheet consists of 256 columns (labeled A, B, C,. .. IV) and 65,536 rows (labeled 1, 2, 3,. ..). The rows and columns define cells (A1, H27, etc.), which constitute the worksheet. Information can be entered into a cell from the keyboard after the cell has been selected, usually with the mouse pointer. Data can also be entered into a cell, or many cells, by calculation. The Excel 2000 for Windows document window is shown in Figure 1-1. Depending on your monitor, your screen may show a different number of rows or columns. 

You can edit cell entries in one of two ways — either in the formula bar or by using the Edit Directly In Cell feature. When you select a cell that contains an entry, the contents of the cell appear in the formula bar. As soon as you begin to enter a new value, the old value disappears. To make minor editing changes in the old entry, place the mouse pointer in the text at the point where you want to edit the entry. The mouse pointer becomes the vertical insertion-point cursor. You can now edit the text in the formula bar using the Copy, Cut, Paste or Delete commands or keys. Complete the entry using the Enter button in the formula bar, or by pressing the Enter key on the keyboard. 

Excel Tip. Sometimes it s difficult to select a chart element by clicking on it (for example, if two chart elements are almost superimposed). Instead of selecting with the mouse pointer, you can use the up and down arrows on the keyboard to select chart elements. This allows you to select each chart element in turn (Chart, Plot, Axis, Series 1, etc.) the name of the selected chart element is displayed in the reference area of the formula bar. By using the left and right arrows, you can select related chart elements within a group (e.g.. Series 1 Point 1, Series 1 Point 2, etc.). 

To detect a single keypress, you can PEEK location 197 as is done in lines 14 and 15 (Z=197). Sometimes, however, you want to let the user do two things at once from the keyboard. In this program, for instance, you can select effects with a function key and simultaneously change the program frequency or pause the sound. 

Deleting objects Select the object and press the Del key on the keyboard, or right-click the object and select Delete from the menu that appears. 

Ektachem DT-60 II is the basic instrument (further extensions are the DTE module for electrolytes and the DTSC module for enzymes) the course of the analysis is monitored from the Ektachem DT-6011, the dialogue with the user is effected via a keyboard and display and the result is computed and printed out. The user selects the slide required for the desired analysis, removes it from the packing and inserts it into the sample receiver unit. The undiluted serum is applied to the slide by means of an automatic pipette (Fig. 16). Pipetting of the sample is monitored via an optical detector. Subsequently, the time cycle for the period of incubation and measurement is started. Incubation for 5 minutes is effected at 37°C in the incubator to which the slide has been transported automatically. 

Figure 6. CAMSEQ/M provides a brief description of each input item for the selected options. A full description of the option is available by pressing the help key (user key 10 on the Tektronix keyboard) and entering the option name.

With this selection, the user can enter new VLE data from the keyboard, or use previously entered VLE data for correlation with IPVDW or 2PVDW models.)...
