A Front-Panel Menu Tutorial
This section is a step-by-step tutorial which shows how to use the |
|
front-panel menu. We recommend that you spend a few minutes with this |
2 |
tutorial to get comfortable with the structure and operation of the menu. |
|
The menu is organized in a top-down tree structure with three |
|
levels (menus, commands, and parameters). You move down |
|
or up the menu tree to get from one level to the next. Each of the |
|
three levels has several horizontal choices which you can view by |
|
moving left < or right > . |

1Turn on the menu.
You enter the menu on the “menus” level. The MEAS MENU is your first choice on this level.
A: MEAS MENU
2 Move across to the SYS MENU choice on this level.
|
|
There are six menu group choices available on the “menus” level. Each |
|
|
|
choice has a letter prefix for easy identification (A: , B: , etc.). |

4Move across to the BEEP command on the “commands” level.
There are eight command choices available in the SYS MENU. Each choice on this level has a number prefix for easy identification (1: , 2: , etc.).
6: BEEP
5Move down a level to the BEEP parameter choices.
The first parameter choice is “ON” for the BEEP command (the beeper setting is stored in non-volatile memory and “ON” is the factory setting).
ON
6Move across to the “OFF” choice.
There are two parameter choices for BEEP.
OFF
7Save the change and turn off the menu.
The multimeter beeps and displays a message to show that the change is now in effect. You are then exited from the menu.
