sub-menus are Temperature and pH or ORP/Redox. Under each sub-menu are prompts. Under
PROGRAM, the sub-menus for 6081 are, Temp, Measurement, Security, HART, Diagnostics, and

messages to aid in troubleshooting. “Fault” or “Warn” appears in the main display to alert the

Security
6.5.1
How the Security Code Works
Use security codes to prevent accidental or unwanted changes to program settings, displays, and
calibration. Two three-digit security codes can be used to do the following…
a. Allow a user to view the default display and information screens only.
b. Allow a user access to the calibration and hold menus only.
c. Allow a user access to all the menus.
1. If a security code has been programmed, pressing MENU causes the security screen to appear.
2. Enter the three-digit security code.
a. If a security code has been assigned to configure only, entering it will unlock all the menus.
b. If separate security codes have been assigned to calibrate and configure, entering the
calibrate code will allow the user access to only the calibrate and hold menus; entering the
configuration code will allow the user access to all menus.
3. If the entered code is correct, the main menu screen appears. If the code is incorrect, the
Invalid Code screen appears. The Enter Security Code screen reappears after two seconds.
Refer to section 8.5 to program the security codes.
