Emerson Micro Motion 1600 - 16.10.6 Consistently incorrect mA measurement; 16.10.7 mAO correct at lower current, but incorrect at higher current; 16.10.8 mAO goes in and out of fault conditions; 16.11 Status alerts, causes, and recommendations

2. Verify the measurement units configured for the output.
3. Check the Fault Action settings.
4. Check the settings of Upper Range Value and Lower Range Value.
5. Check the mA Output trim.
16.10.6 Consistently incorrect mA measurement
Cause
• Loop problem
• Incorrect measurement unit configured for process variable
• Incorrect process variable configured
• LRV and URV are not set correctly
• mA Output Direction not set correctly
Recommended actions
1. Check the mA Output trim.
2. Verify the measurement units configured for the output.
3. Verify the process variable assigned to the mA Output.
4. Check the direction parameters.
16.10.7 mAO correct at lower current, but incorrect at higher current
Cause
The mA loop resistance may be set too high.
Recommended actions
Verify that the mA Output load resistance is below the maximum supported load.
See the installation manual for your transmitter.
16.10.8 mAO goes in and out of fault conditions
Cause
There is a problem with the interaction between the Output Saturated alert and the fault action configured for
the output.
Recommended actions
1. Identify and resolve the fault.
2. Verify that the mA Output load resistance is below the maximum supported load (600 ohms).
3. Configure the transmitter to ignore the Output Saturated alert or the relevant conditions.
4. Change the configuration of Fault Action from Downscale to another option.
16.11 Status alerts, causes, and recommendations
Not all of these alerts may apply to your type of transmitter.
