Tip
If you do not know the correct value for Off-Line Password, wait 30 seconds. The password
screen will time out automatically and you will be returned to the previous screen.
4. If Scroll flashes on the display, activate the Scroll optical switch, then the Select optical
switch, and then the Scroll optical switch again.
The display will prompt you through this sequence. The Scroll-Select-Scroll sequence is
designed to guard against accidental activation of the off-line menu. It is not
designed as a security measure.
5.
To exit a display menu and return to a higher-level menu:
• Activate Scroll until the EXIT option is displayed, then activate Select.
• If the EXIT option is not available, activate Scroll and Select simultaneously and
hold until the screen returns to the previous display.
6. To exit the display menu system, you can use either of the following methods:
• Exit each menu separately, working your way back to the top of the menu
system.
• Wait until the display times out and returns to displaying process variable data.
A.3.1 Enter a floating-point value using the display
Certain configuration values (for example, Lower Range Value and Upper Range Value) are
entered as floating-point values. The display supports both decimal notation and
exponential notation for floating-point values.
The display allows you to enter a maximum of 8 characters, including the sign. The decimal
point is not counted as a character. Exponential notation is used to enter values that
require more than 8 characters.
Enter a floating-point value using decimal notation
Decimal notation allows you to enter values between –9999999 and 99999999. You can
use the decimal point to enter values with a precision of 0 through 4 (4 characters to the
right of the decimal point).
Decimal values entered via the display must meet the following requirements:
• They can contain a maximum of 8 digits, or 7 digits plus a minus sign (−) to indicate
a negative number.
• They can contain a decimal point. The decimal point does not count as a digit. The
decimal point must be positioned so that the precision of the value does not exceed
4.
When you first enter the configuration screen, the current configuration value is displayed
in decimal notation, and the active character is flashing. If the value is positive, no sign is
displayed. If the value is negative, a minus sign is displayed.
