9. ENABLING & LOCKING OUT MENU ITEMS
For security reasons and ease of operation, any and all menu items
may be disabled or "locked out" so that they are no longer directly
accessible from the front panel. Each function to be enabled is set
to "0" and each function to be disabled is set to "1" in menu items
Loc 1-4. These menu items can in turn be locked out by installing an
internal hardware jumper. With the jumper installed, the operator
only has access to enabled menu items. With the jumper removed,
the operator also has access to the Loc 1-4 menu items.
SETTING HARDWARE LOCKOUT JUMPER
To access the lockout jumper, remove the rear panel per Section 9
and locate jumper “a” in the lower portion of the power supply board
next to the input connectors (see figure at right).
SETTING SOFTWARE LOCKOUTS
When setting up the meter, it may be neces-
sary to enable specific menu items by setting
the corresponding lockout digit to 0. Be sure
to reset the lockout digit to "1" if you do not
want the menu item to be changed by an
operator.
