Analog output diagnostic alerts
Two diagnostic alerts are shown under the Diagnostics heading.
The first is mA Output Fixed. This alerts the user that the 4–20 mA analog output signal is
fixed at a constant value and is not representative of the HART Primary Variable. This
diagnostic alert may also be triggered if “Loop Current Mode” is disabled, the device is in
alarm, or if “Test Calculation” is running.
The second diagnostic is mA Output Saturated. This alerts the user that the measured
Primary Variable has exceeded the range points defined for the 4–20 mA analog output
signal. The analog output is fixed at the user-defined high or low saturation point and is
not representative of the current HART Primary Variable.

Flow/energy calculation verification (test calculation)
About this task
Mass and energy flow Fast Keys
1, 2, 3
(Fully compensated mass and energy flow feature board only):
The Flow and Energy Calculation Verification Test allows the user to verify the flow
configuration of the Rosemount 3051SMV by entering expected values for the differential
pressure, static pressure, and process temperature variables. Under the Flow/Energy
Calculation Verification heading, perform the following steps:
Procedure
1. Select the Enable Test Calculation button.
2. Select Simulate DP option. Select Next.
