9. ENABLING & LOCKING OUT MENU ITEMS
For security reasons and ease of meter 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 disabled is set to "1"
in menu items Loc 1, Loc 2 or Loc 3, and each function to be enabled is
set to "0." The top menu items Loc 1, Loc 2 and Loc 3 can in turn be
locked out by installing an internal hardware jumper. With the jumper
installed, the operator only has access only to enabled menu items. With
the jumper removed, the operator also has access to menu items Loc 1,
Loc 2
and Loc 3.
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 necessary to
enable specific menu items by setting the corres-
ponding 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.

Press the

jumper must be removed (see above).
