10. ENABLING & LOCKING OUT MENU ITEMS
For security reasons and ease of meter operation, any or 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" under menu headers
Loc 1-4 , while each function to be
enabled can be set to "0." Access to the menu headers Loc 1-4 can in
turn be locked out by installing a hardware jumper on the power
supply board. With the jumper installed, the operator only has access
to previously enable menu items, not to the menu headers
Loc 1 - 4
and hence not to the menu items below. With the jumper removed,
the operator has access to menu headers
Loc 1
-
4
and hence to the
menu items below.
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).
