Rosemount 1151
Common Functions The following tasks are a common part of a transmitter commissioning.
Setting the Loop to Manual
When preparing to send or request data that would disrupt the loop or change
the output of the transmitter, set the loop to manual. The HART
Communicator will prompt for this setting when necessary. Keep in mind that
simply acknowledging this prompter does not set the loop to manual. It is only
a reminder; the loop must be set to manual as a separate operation.
Change Non-Output Related Information
The Rosemount 1151 Smart contains several configuration parameters that
do not directly affect the transmitter output. These parameters include:
•Date
• Descriptor
• Message
• Meter type

Setting Units
By setting the output units, a process can be monitored using the specified
units. This is important if a plant uses units which differ from the default
values. Output units can be selected from among 14 output options:
Reranging One of the most common configuration tasks involves reranging the
transmitter 4 and 20 mA points.
Reranging matches the transmitter range points with the applied process
pressures. It can be performed three ways:
• using the communicator only
• using the communicator and a reference pressure
• using the integral zero and span buttons and a reference pressure
