3.5.4 Display password
Some of the display menu functions, such as accessing the off-line menu, can be protected by a
display password. For information about enabling and setting the display password, refer to
Section 8.9.
If a password is required, the word
CODE? appears at the top of the password screen. Enter the digits
of the password one at a time by using
Scroll to choose a number and Select to move to the next
digit.
If you encounter the display password screen but do not know the password, wait 60 seconds without
activating any of the display optical switches. The password screen will time out automatically and
you will be returned to the previous screen.
3.5.5 Entering floating-point values with the display
Certain configuration values, such as meter factors or output ranges, are entered as floating-point
values. When you first enter the configuration screen, the value is displayed in decimal notation (as
shown in Figure 3-4) and the active digit is flashing.
