Menu Bar - Ecom Instruments MCAL 4200 Instruction Manual

2.2 Menu Bar

The parameters on the display are controlled by the menu bar, which is located at the bottom
of the LCD. The function keys (F1, F2, and F3) are used to navigate through all the levels and
choices of the menu bar. The top level of the menu is the home menu. It can be accessed
anytime by pressing the HOME key. There are three variations of the home menu: the input
home menu, the output home menu, and the pulse home menu.
In the input home menu the only active options are [MENU] and [LIGHT]. The [MENU] option
is used to enter the next level of the menu bar, the main menu. Press the corresponding
function key (F1) to enter the main menu. The [LIGHT] option is used to turn on the LCD
back light. Press the corresponding function key (F2) to turn on the back light.
In the output home menu there are three active options, [MENU], [LIGHT] and [STEP] or
[RAMP]. The first two options work the same as in the input home menu. The third option is
selectable in the Auto Function Menu and is used to turn on and off the selected auto
function. See Section 4.2, Using the Automatic Output Functions. Also leaving this menu or
pressing the Home button will stop the auto functions.
The pulse home menu also has three active options, [MENU], [TRIG], and [COUNTS]. The
[TRIG] and [COUNTS] options are used for pulse simulation. The function of these options is
explained in Section 4.7 (Sourcing a Pulse train).
The next level of the menu bar is the main menu. The levels under the main menu depend on
what mode the calibrator is in.
The main menu has three active options [UPPER], [LOWER], and [MORE].
Choosing [UPPER] calls up the parameter selection menu for the upper display. Choosing
[LOWER] calls up the parameter selection menu for the lower display. [MORE] enters the next
menu level.
The Auto Function Menu is the next menu if you are in source mode. Its options are
[AUTO FUNC], [NEXT] and [DONE]. [AUTO FUNC] allows you to adjust the Automatic Output
Function parameters. [NEXT] proceeds to the next menu level and [DONE] returns to the
home menu. See Section 4.2, Using the Automatic Output Functions.
