4.4.8 Set Error Handling? (cont.)
You have completed the Setup Menu. At the Main Menu prompt, press [NO] to leave the Setup Menu and progress to
the Outputs Menu.
4.5 The Outputs Menu
The second main menu, the Outputs Menu , enables users to select which 4-20 mA output (A or B) to adjust, and to
enter all necessary information for either or both outputs.
The TMO2D provides a choice of one isolated 0/4-20 mA output, or two isolated 0/4-20 mA outputs. You can set both
options for a 0 to 20-mA or a 4-20 mA response, and scale the output anywhere within the range of the transmitter.
Note:
The display is programmed to accept settings for two outputs; however, if only a single isolated output is used,
only output A is effective.
The steps in the following example illustrate how to set up outputs. In this instance, output A will have a 0 to 20-mA
range, with 0 mA equal to 0% oxygen and 20 mA equal to 100% oxygen. (Appendix B offers a flow diagram of the
Outputs Menu in Figure 26 on page 79.)
