1. Verify level.
2. Check the settings of the 4-20 mA range values.
3. Verify output is not in alarm condition.
4. Check that power wires are connected to the correct signal terminals.
5. Perform Calibrate Analog Out.
1. Verify power supply voltage is adequate at signal terminals.
2. Check for external electrical interference.
3. Under turbulent conditions with low level rates, consider increasing the
Damping value.
Verify level is between the 4 and 20 mA set points.
Verify output is not in alarm condition.
Verify device is not in loop test or simulation mode.
1. Verify power supply voltage is adequate at signal terminals.
2. Check load resistance (250 ohms minimum).
3. Check if device is at an alternate HART address.
4. Check current analog output value to verify that device hardware works.
