Introduction

This section will help you use the Model 8718's menu system.
The menu system allows you to enter and store data and to
select various options during operation.

The menu system is always available from any measurement
mode. It is accessed by pressing the appropriate function key
that corresponds to

MENU

on the bottom line of the display

screen.

The menu system is comprised of three menu screens where all
the basic options are listed. A specific menu item is selected by
pressing the appropriate numeric key that corresponds with that
menu item. Instructions or sub menus appear when one of the
basic menu options is selected. If it isn't clear what to do, press
the

Help

key.
