Emerson Micro Motion 1600 - 16.6.4 Unusually low density reading; 16.7 Discrete Output troubleshooting; 16.7.1 No Discrete Output; 16.7.2 Loop test failed

16.6.4 Unusually low density reading
Cause
• Two-phase flow
• Incorrect calibration factors
• In low-frequency meters, erosion or corrosion
Recommended actions
1. Check for alerts, especially Drive Overrange.
2. Check your process conditions against the values reported by the device.
3. Verify all of the characterization or calibration parameters. See the sensor tag or the calibration
sheet for your meter.
4. Purge sensor tubes.
5. Check for tube erosion, especially if the process fluid is abrasive.
6. Perform Smart Meter Verification.
16.7 Discrete Output troubleshooting
16.7.1 No Discrete Output
Cause
• Output not powered
• Wiring problem
• Circuit failure
Recommended actions
1. Check the power supply and power supply wiring if power source is set to external.
2. Verify the output wiring.
3. Verify that the channel is wired and configured as a Discrete Output.
4. Contact customer service.
16.7.2 Loop test failed
Cause
• Output not powered
• Power supply problem
• Wiring problem
• Circuit failure
Recommended actions
1. Check the power supply and power supply wiring.
2. Verify the output wiring.
3. Contact customer service.
