Entering and Changing Setup Window Parameters

The Setup dialog box changes the parameters and switches that the technique uses in running an experiment. Access a parameter in the Setup dialog box using either the keyboard or the mouse.

From the keyboard, use the TAB key to advance down the Setup dialog box. The parameter that is currently selected is highlighted in reverse video or with a dotted box. When the parameter that you wish to edit is active, replace it by typing a new value. The old value is erased as soon as you press a printing character. To retain and edit the old parameter, click a cursor-movement key (such as a direction key or HOME key) before the first printable key.

Do not press the ENTER key after you type the new value unless it is the last change required in the Setup window. The ENTER key is equivalent to OK, which accepts all Setup entries and starts the experimental run.

If you use the mouse to access a parameter, just click the mouse somewhere within the value. You get an editing cursor in the value. Use the DELETE, backspace, and direction keys to move around within and erase the old parameter value. Any new digits that you type are inserted after the current location of the editing cursor. Do not press the ENTER key when you have finished typing the new value unless it is the last change required in your Setup.

Enter most numbers in floating-point format. We recommend that you only enter a decimal point when actually required. For example, enter 1 not 1.0. If you need to enter very large or very small values, use E format. 1.23E-4 equals 0.0001234. Note that E (upper and lower case) are the only valid letters that may be entered in a number. Unless otherwise noted, all values in the standard techniques are entered in SI units.

On/off switches in Setup are indicated by square check boxes. With the mouse you alter the state of a switch by clicking on the box to activate or deactivate. From the keyboard, tab down until the switch state is enclosed in a dotted line, then press the space bar to change the state. The label for a switch always indicates the current state of the switch, not the state you will get after switching.
