Basic Configuration/Start-Up

4.4 Basic configuration

This section describes the various HART commands used to configure the Rosemount 3300

Series Transmitters for level measurements. The transmitter outputs a 4-20 mA signal

proportional to the primary variable. Three additional variables are available through the HART

signal.

Table 4-1. Device Revision 2, HART Communicator Fast Key Sequence

4.4.1 Transmitter variables

You can assign up to four transmitter variables. Typically, the Primary Variable (PV) is configured

to be Aggregate Level, Interface Level, or Volume.

For Rosemount 3301, the PV is typically set to be Level. If the transmitter is in the Immerse

Probe mode (see Measurement mode on page 71), the PV is normally set to Interface Level.

For Rosemount 3302, the PV is typically set to Interface Level, but Level and other options can

also be used.
