1OPERATING INSTRUCTIONS

This chapter presents detailed instructions on the operation of the 9412/9412A.

Overview

The 9412/9412A uses a single -line LCD to display menu selections. The front panel keys are used to "navigate" through sets of menus to set various options and control the pulse genera- tor. Some keys are only active at certain times or have different behavior depending on what state the menus are in -- once understood, the menus can be quickly and easily manipulated. The 9412/9412A also contains non-volatile memory for storing up to four (4) (eight (8) for the 9412A) configurations, so you need not go through the entire setup process each time the in- strument is used.

Selecting Menu Items

The menu items in the 9412/9412A are arranged in sets. Pressing the		key will toggle be-
tween sets of menus, while the	key will toggle between menu items within the current set.

Hold down the Left arrow key to receive a short description of the current menu item. Press- ing and holding the Right arrow key will display the valid range for that item.

Numeric Input Mode

When the current item is numeric, the system enters the Numeric Input mode. In this mode, the Left and Right arrow keys are used to select a digit to edit. The selected digit blinks to identify itself as the active digit. The Up and Down arrow keys are then used to increment or decrement this digit. When the left most digit is active, pressing and holding the Left arrow key will display a brief description of the current item. When the right most digit is active, pressing and holding the Right arrow key will display the range and units for the current item.

Item Edit Mode

When the current item is non-numeric, the Up and Down arrow keys are used to select among different options for the entry. The Left and Right arrow keys are used to display a description of the item.
