10. 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 accessible from the front panel. Each function to be
disabled can be set to "1" in menu items Loc 1 through Loc 4, and
each function to be enabled can be set to "0." The Loc 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 has access to
the Loc menu items.
SETTING THE HARDWARE LOCKOUT JUMPER
To access the lockout jumper, remove the rear panel per Section
10 and locate jumper “a” in the lower portion of the power supply
board next to the input connectors (see figure).
SETTING SOFTWARE LOCKOUTS
Set the lockout digit to "1" if you do not want the
menu item to be changed by an operator, other-
wise to “0”.
Loc 1 Loc 2 Loc 3 Loc 4
Press the MENU key until Loc 1, Loc 2, Loc 3
or Loc 4 is displayed. Note: hardware lockout
jumper “a” must be removed (see above).
