Function Keys
Use the four function keys, marked F1 through F4 located below the LCD
to perform software functions as indicated by the dynamic labels. Different
labels appear over the four function keys as you move among the various
menus.
On-line Menu
When connected to a HART compatible device, simply press the ON Key
to display the On-line Menu. This menu contains the most critical
information about the connected device and your measurement including:
• Model Number
• User-defined Tag Number
• Flow Rate Units of Measure
• Analog Output LoRange
• Analog Output HiRange
a. Simulation Mode
The HART Communicator provides a mode that allows you to simulate
an on-line connection to a specific HART compatible device. The
simulation mode is a training tool that enables you to become
familiar with a device before configuring it in a critical environment.
Access to the simulation mode is through the utility menu.
For more details and instructions on use of the Emerson Model 275
Communicator please contact Brooks Service Department
Representative or your local Emerson office.
b. Recalibration of Analog Transmitter Output (spanning high and
low)
At any time after factory calibration, shipment, installation, or service, the
SMM transmitter can be recalibrated by overwriting any of the
previous calibration point-pairs, assuming that the user can provide
a series of accurate rates of flow through the meter. If preferred, the
meter with transmitter may be returned for recalibration at the
Brooks Service Department for a fee.
c. Basic Transmitter Setup Parameters
Refer to Figures 3-1 and 3-2. These are meter identification parameters
set prior to shipment of the meter.
Flowmeter Identification: Model Number, Serial Number, Tag Name
Flowmeter Configuration: Low Flow Cutoff, Calibration Factor, Flow Rate
