Emerson Micro Motion 1600 User Manual

16.19 Perform transmitter output tests
A loop test is a way to verify that the transmitter and the remote device are communicating properly. A loop
test also helps you know whether you need to trim mA Outputs.
Prerequisites
Follow appropriate procedures to ensure that testing will not interfere with existing measurement and control
loops.
16.19.1 Perform a mA loop test using the display
Prerequisites
Before performing an mA loop test, configure Channel B as an mA Output.
Follow appropriate procedures to ensure that testing will not interfere with existing measurement and control
loops.
Procedure
1. Choose Menu → Service Tools → Output Simulation and select the mA Output.
2. Set Simulation Value to 4.
3. Start the simulation.
4. Read the mA current at the receiving device and compare it to the transmitter output.
The readings do not need to match exactly. If the values are slightly different, you can correct the
discrepancy by trimming the output.
5. Choose New Value.
6. Set Simulation Value to 20.
7. Start the simulation.
8. Read the mA current at the receiving device and compare it to the transmitter output.
The readings do not need to match exactly. If the values are slightly different, you can correct the
discrepancy by trimming the output.
9. Choose Exit.
Postrequisites
• If the mA Output readings are within 200 microamps of each other, you can correct this discrepancy by
trimming the output.
• If the discrepancy between the mA Output readings is greater than 200 microamps, or if at any step the
reading was faulty, verify the wiring between the transmitter and the remote device, and try again.
• You must end the test. It will not time out by itself. A power cycle will also end the test.
16.19.2 Perform a Frequency Output test using the display
Prerequisites
Before performing a Frequency Output test, configure Channel B as a Frequency Output.
Follow appropriate procedures to ensure that testing will not interfere with existing measurement and control
loops.
Procedure
1. Choose Menu → Service Tools → Output Simulation and select the Frequency Output.
2. Set Simulation Value to 1.
