Emerson recommends testing the 4-20 mA (1-5 Vdc) points in addition to alarm levels when
installing, repairing, or replacing a transmitter.
The host system may provide a current measurement for the 4–20 mA (1-5 Vdc) HART
output. If it does not, connect a reference meter to the transmitter by either connecting
the meter to the test terminals on the terminal block or shunting transmitter power
through the meter at some point in the loop.
For 1-5 V output, voltage measurement is directly measured from

Procedure
From the HOME screen, enter the fast key sequence:
Fast keys
Perform an analog loop test using AMS Device Manager
Procedure
1. Right-click the device and go to Methods → Diagnostics and Test → Loop Test.
2. Set the control loop to Manual and select Next.
3. Follow screen prompts to perform a loop test.
4. Select Finish to acknowledge the method is complete.
Perform an analog loop test using a local operator interface
(LOI)
To perform an analog loop test using the LOI< you may set the 4 mA (1 V), 20 mA (5 V), and
custom mA points manually.
Procedure
See Figure 2-17

2.8.3 Simulating device variables
You can temporarily set the Pressure, Sensor Temperature, or Scaled Variable to a user-
defined fixed value for testing purposes.
Once the simulated variable method is left, the process variable will be automatically
returned to a live measurement. Simulate device variables is only available in HART
Revision 7 mode.
