14.1 Quick guide to troubleshooting

The meter may report or exhibit issues that are caused by installation, wiring, configuration, and process
problems — including external devices, or mechanical issues with the sensor itself.
To identify and resolve problems as effectively as possible, work through the following list of suggestions:
• If this is a first installation:
— Verify the power wiring and power supply.
— Verify the output wiring. The outputs must be powered externally.
— Verify the grounding.
— Verify cable shielding.
— Perform loop tests for each output.
— Check the sensor installation and orientation. Ensure that it is appropriate for your application.
— Ensure that the installation meets temperature and/or pressure requirements.
• Check for active status alerts and follow the recommendations.
• If the device appears to be functioning correctly, but the process data is not acceptable, review the
symptoms and suggestions in the following sections:
— Density measurement problems
— Temperature measurement problems
— Gas measurement problems
— Concentration measurement problems
• If the device appears to be functioning correctly, but the control loop is not performing as expected:
— Verify the output wiring.
— Ensure that all external devices are operational, are receiving data, and are configured appropriately.
— Use sensor simulation to test boundary conditions and system response.
