4.1 Introduction
The TMO2D display contains an interactive, user-friendly program that enables the user to change operating
parameters as desired.
This user program has six main menus. Use the front panel keypad and display to check or change the settings for
current operating parameters. The TMO2D stores data in memory and will retain it for several years if the main power
is lost. New data overrides any previously entered data.
The user program consists of six main menus:
• Setup
• Outputs
• Relays
• Tests
• Calibration
• System Log
Note: The TMO2D can function as a display package for a variety of Panametrics transmitters. As an example, this
chapter describes TMO2D programming when the TMO2D is used with a TMO2 or XMO2 oxygen transmitter.
4.2 Entering Data into the User Program
To enter data into the user program or to check previously entered values, enter the Menu Mode. When the power is
turned on, the TMO2D enters the Operate Mode. To enter the Menu Mode:
1. Press the [NO] key.
2. Key in the code [1] [2] [3]. The TMO2D will display an asterisk (*) after you enter each digit.
If an incorrect code is entered or a non-numeric ([YES]/[NO] or arrow) key is pressed rather than 1 2 3, the LCD will
automatically resume displaying data, and you must press [NO] to re-attempt the code. Once all three digits have
been entered correctly, the display will cease collecting data and the LCD will switch to Menu Mode.
The LCD screen now displays the Setup Menu, the first of the six main menus. At this display, press [YES] to enter this
menu, or [NO] to scroll to the next menu. Pressing [NO] repeatedly scrolls through all six main menus.
Note: The first six options are main menus, while the RESUME prompt enables users to exit the Menu Mode and
return to Operate Mode.
