Section 3: Configuration

Configuration
Descriptor
The Descriptor variable provides a longer user-defined electronic label to assist with more
specific transmitter identification than is available with the tag variable. The descriptor may be
up to 16 characters long and has no impact on the operation of the transmitter or the Field
Communicator.
Message
The Message variable provides the most specific user-defined means for identifying individual
transmitters in multi-transmitter environments. It allows for 32 characters of information and is
stored with the other configuration data. The message variable has no impact on the operation
of the transmitter or the Field Communicator.
Sensor serial number
The Sensor S/N variable provides a location to list the serial number of the attached sensor. It is
useful for identifying sensors and tracking sensor calibration information.
3.4.8 Diagnostics and service
Test device
The Test Device command initiates a more extensive diagnostics routine than is performed
continuously by the transmitter. The Test Device menu lists the following options:
1 Loop test verifies the output of the transmitter, the integrity of the loop, and the
operations of any recorders or similar devices installed in the loop. See “Loop test”
below for more information.
2 Self Test initiates a transmitter self test. Error codes are displayed if there is a problem.
3 Master Reset sends out a command that restarts and tests the transmitter. A master
reset is like briefly powering down the transmitter. Configuration data remains
unchanged after a master reset.
4 Status lists error codes. ON indicates a problem, and OFF means there are no
problems.
Loop test
The Loop Test command verifies the output of the transmitter, the integrity of the loop, and the
operations of any recorders or similar devices installed in the loop. To initiate a loop test,
perform the following procedure:
