Figure 2.3.1—The Main Coupler Screen
Notice that F1, F4, and F5 are written in large letters. They take you to the Menu, ANSI 96, and
Probe Screens, respectively. F2, F3, F6, F7, and F9 are all settings that pertain to the current Main
Coupler Screen.
2.3.2 Customizing the function keys
As described in Section 2.3.1, the functions of F1 through F9 will vary, depending upon the cur-
rent screen. Most of the time, the functions of these keys in each screen are set at the factory and
cannot be changed. However, the FP40 does allow you to customize the function of several keys.
This allows you to change the FP40 screen to fit your testing needs. Most of these are set in the
FUNCTION KEY DEFIN section of the General Setup Menu.
MAIN F2 & MAIN F3: These settings change the function of F2 and F3 in the Main Coupler
Screen. Usually, you can select from AVG, GAIN, MULTICURVE, and TELECOIL. (These options are
explained in Chapter 3.) The available settings are dependent upon the options on your FP40, so
you may have some additional functions available.
MAIN F4: This setting changes the automated coupler test sequence available from the Main
Coupler Screen. Depending upon the options you purchased with your FP40, you may have only
one choice for this key, or you may have multiple choices. See Chapter 4 for more information on
automated test sequences.
SETUP F2 & SETUP F3: These selections allow you to customize the function of F2 and F3 in the
General Setup Menu. This allows you to adjust functions used in the Main Coupler Screen that you
might not need to change often.
For instance, if you always want to have Multi-Curve turned on in the Main Coupler Screen, you
can have it set to ON in the General Setup Menu, freeing up either F2 or F3 in the Main Coupler
Screen for a more commonly changed function, such as CIC.
