4.15.3 Nulling the Console
After an Image has been loaded from disk, pressing the Select button on any module
causes the console to leave Image Display mode and enter the Horizontal Nulling mode,
described below. The console returns to Image Display mode whenever there are no
modules selected.

Nulling Methods Overview
To allow the engineer to quickly null the console and to allow for different operating
habits, three nulling modes are provided. These nulling modes are explained in diagrams
on the following pages.
• Horizontal Nulling allows the operator to null all items on the console in horizontal,
console-wide rows. Horizontal Nulling is the fastest way for a single person to null the
entire console.
• Vertical Nulling allows multiple modules to be nulled individually and independently.
Vertical Nulling permits more than one person to null the console, module by module.
• Fast Switch Nulling allows the engineer to recall and null all mechanical switch settings
on the console in one operation.
NOTE:
Switch states are also be recalled and nulled in Horizontal and Vertical modes.
Fast Switch Nulling is provided only as a streamlined switch recall method.

Horizontal Nulling Mode
Horizontal Nulling uses one input module as a “null controller” to select a module control,
which then becomes available for nulling across the entire console.
In Horizontal nulling mode, the operator selects a module as the “Null Controller”, by
simply pressing its Select button. When the operator adjusts an item on the Null
Controller, the same item on the other modules become available for nulling. To null to
another control, the operator simply adjusts that control on the Null Controller module.
