Configuration

2.1 Configuring the transmitter
The Rosemount 148 must be configured for certain basic variables
to operate. Transmitters are pre-configured in the factory to
order specifications or factory defaults. Configuration may be
required if the transmitter is not configured or if the configuration
variables need revision. This can be done in two ways: by ordering
factory-configuration by Emerson Automation Solutions, or by
using the Rosemount 148 PC Programming interface in a bench
configuration setting. The Rosemount 148 PC Programming Kit
includes configuration software and a communication modem. The
Rosemount 148 device will need an external power supply of 12 to
42.4 Vdc for configuration. To configure the transmitter:
Procedure
1. Hook up the transmitter and a load resistor (250–1100 ohms)
wired in series with the power supply.
2. Attach the modem in parallel with the load resistor and
connect it to the PC.
2.2 Verify the transmitter configuration
If the transmitter has a sensor connected (either a test sensor or
actual installation hardware), the configuration can be checked using
the Information tab on the Rosemount 148 PC Programmer interface.
Select Refresh to update the status and confirm that the transmitter
has been configured correctly. For troubleshooting, refer to the
