If ENTER is pressed again, the display moves to the fol-
lowing display:
LOGGED HELP

)
At this point, the analyzer will display the last fault the sys-
tem has seen, if any are present. You may scroll through
the fault logs to view what the last 25 faults were. Use the
right and left arrow keys to scroll through the fault logs. To
return to the beginning, press

When a top level menu is selected, a new set of menu
items may be offered: for example:

Pressing ENTER with any of the above displayed menus,
will display additional sub-menus within the selected
menu. In some cases, such as
DRIVE , the next level is the
parameter or information to be changed. Refer to the flow
chart for what menus are available within the top level
menus. You may only view the personality settings for
selected menus while in access level 2. Remember, you
may always cancel a selected menu item by pressing the
ESC. key.
6.5 CHANGING THE ACCESS LEVEL OF THE
HAND HELD ANALYZER
When the analyzer is first connected, you will be in access
level 2 which enables you to only view most settings
which cannot be changed until you enter a password to
advance to a lower level. This ensures that a setting can-
not be accidentally altered. To change the access level,
the correct password must be entered. To enter the pass-
word, scroll to the
ACCESS LEVEL menu. For example:
MENU:
ACCESS LEVEL 2
Press ENTER to select the ACCESS LEVEL menu.
Using the UP or DOWN arrow keys, enter the first digit of
the password, 3.
