Quick Start Guide
NOTICE
This guide provides basic guidelines for the Rosemount 248. It does not provide instructions for detailed
configuration, diagnostics, maintenance, service, troubleshooting, or installations. Refer to the Rosemount
248 Reference Manual for more instruction. The manual and this guide are also available electronically on
Emerson.com/Rosemount.
Explosions could result in death or serious injury.
Installation of this transmitter in an explosive environment must be in accordance with the appropriate local,
national, and international standards, codes, and practices. Review the Hazardous Locations Certifications for
any restrictions associated with a safe installation.
Process leaks may cause harm or result in death.
Install and tighten thermowells or sensors before applying pressure.
Do not remove the thermowell while in operation.
Electrical shock can result in death or serious injury.
Avoid contact with the leads and terminals. High voltage that may be present on leads can cause electrical
shock.
Unless marked, the conduit/cable entries in the transmitter housing use a 1/2–14 NPT thread form. Entries
marked “M20” are M20 1.5 thread form. On devices with multiple conduit entries, all entries have the
same thread form. Only use plugs, adapters, glands, or conduit with a compatible thread form when
closing entries.
When installing in a Hazardous Location, use only appropriately listed or Ex certified plugs, adapters or
glands in cable/conduit entries.

1.3 Rosemount 248 PC Programmer Kit installation
1. Install all necessary software for Rosemount 248 PC configuration:
a. Install the Rosemount 248C software.
Place the Rosemount 248C CD-ROM in the drive.
Run setup.exe from Windows™NT, 2000, or XP.
b. Install the MACTek®HART Modem drivers completely before beginning
bench configuration with the Rosemount 248 PC Programming system.
Note
For USB modem: Upon first use, configure appropriate COM ports within the Rosemount
248PC software by selecting Port Settings from the Communicate menu. The USB modem
driver emulates a COM port and will add to available port selections in the software’s
drop-down box. Otherwise software defaults to first available COM port, which may not be
correct.
2. Set up configuration system hardware:
a. Hook up the transmitter and load resistor (250-1100 ohms) wired in
series with the power supply (the Rosemount 248 device will need an
external power supply of 12-42.4 Vdc for configuration).
b. Attach the HART modem in parallel with the load resistor and connect it
to the PC.
See Table 1 for spares kit and re-order numbers. For more information, refer to
the Rosemount 248 Reference Manual.
2.0 Mount the transmitter
Mount the transmitter at a high point in the conduit run to prevent moisture
from draining into the transmitter housing.

4.0 Perform a loop test
The loop test command verifies transmitter output, loop integrity, and
operation of any recorders or similar devices installed in the loop.
Note
This is not available with the Rosemount 248C Configuration Interface.
4.1 Initiate a loop test
1. Connect an external ampere meter in series with the transmitter loop (so the
power to the transmitter goes through the meter at some point in the loop.
2. From the Home screen, select: 1) Device Setup > 2) Diag/Serv > 1) Test
Device > 1) Loop Test.
3. Select a discrete milliampere level for the transmitter to output. At Choose
Analog Output, select: 1) 4 mA > 2) 20 mA,or select 3) Other to manually
input a value between 4 and 20 milliamperes.
4. Select Enter to show the fixed output.
5. Select OK.
6. In the test loop, check that the fixed mA input and the transmitter’s mA
output are the same value.
Note
If the readings do not match, either the transmitter requires an output trim or the current
meter is malfunctioning.
After completing the test, the display returns to the loop test screen and allows
the user to choose another output value.
4.2 End the loop test
1. Select 5) End.
