Load Calibration (Tools Menu):

The "Load Calibration" command allows you to use the calibration data from a

previously-saved file for your current Real-time window. When this item is selected, an ‘Open’ dialog box
appears, and the calibration file can be located and opened. Only ELF calibration files (extension *.clb) can be
loaded. The Sensitivity setting that was saved with the calibration file will also be loaded.

Main Menu:

The Main Menu contains important commands you use to perform functions within the software. Some

menu commands can be found directly in the toolbar, however, not all commands found under the menu are
located on the toolbar. The Main Menu changes, depending where your focus lies. The reason for this
difference is because there are some commands that can only be accessed from a Movie Window, and others
from a Real-Time Window. For example, if you have two windows open, one a Real-Time Window, and the
other a Movie Window, the Main Menu will contain a different set of submenus and commands.

Main Window:

When you initiate the ELF software program, the Main Window is displayed on your computer

screen. The Main Window consists of the Menu Bar, Tool Bar, and Main Status Bar, and may contain one or
more Real-time or Movie Windows. The window that is selected is considered the active window or the window
that has focus. See "Focus". Only one window can be active at one time, and the title bars of the other windows
will be grayed out.

Menu Bar:

The Menu Bar provides drop-down menus (submenus) used to control the ELF software program. It is

located at the top of the Main Window.

Minimum Requirements:

The minimum hardware requirements that your computer must meet in order to run the

ELF software and operate the hardware successfully. The minimum requirements are: Pentium 300 MHz with
64 MB RAM and 5 MB of Hard Drive Space. In addition, a 3 ½ Inch Floppy Drive or CD Drive, One 9-pin RS-
232 port per ELF handle, and Windows Operating System (one of the following: 95 / 98 / ME / NT / 2000 / XP).
See "Hardware".

Movie Toolbar (Playback Controls):

This bar is located at the top of the Movie Window, and consists of the movie

playback icons and the Save As icon. See "Playback Controls".

Movie Window:

The Movie Window displays a previously recorded movie. It consists of the display area, scroll bar,

the "Movie Toolbar (with playback controls) and the "Movie Window Status Bar".

Multi-Point Calibration:

Multi-Point Calibration is a method in which at least two known forces are applied to the

sensor and then calculated to convert Digital Output into Engineering Units. See "Calibration".

New (File Menu):

The "New" command opens a new Real-time window, in addition to any other Real-time or Movie

windows that are currently open. The new Real-time window becomes the active window when it is opened. If
more than one Real-time window is open, the force data will be displayed in all windows, in unison. If the
sensor has already been calibrated, this calibration will also apply to the new Real-time window.

Next Frame (Movie Toolbar Playback Controls):

Plays the recording forward one frame each time it is clicked.

Number (View Menu):

The "Number" option displays each COM port as numerical values. Each numerical value is

color coded to indicate the individual COM ports. As time elapses, the numbers change to indicate changes in
force.

Open (File Menu):

The "Open" command displays the Open dialog box, which allows you to open previously

recorded movie files. Only ELF movie files, with the *.flf file extension, can be opened.

Piece Wise Linear Calibration:

This calibration connects each calibration point directly and interpolates between

the values.

Play Backward (Movie Toolbar Playback Controls):

Plays the recording in reverse.

Play Forward (Movie Toolbar Playback Controls):

Plays the recording forward.

Playback Controls:

The Playback controls are used for movie playback functions. The following functions are

available: "First Frame", "Play Backward", "Previous Frame", "Stop", "Next Frame", "Play Forward", and "Last
Frame". See "Movie Toolbar (Playback Controls)".

Port:

See "COM Port".

Previous Frame (Movie Toolbar Playback Controls):

Plays the recording in reverse one frame each time it is

clicked.

Properties (View Menu):

The "Properties" command opens the Properties dialog box, which allows you to change
