Possible cause
The configured board type does not
match the physical board, or the
configured sensor type does not
match the physical sensor.
Internal electronics failure.
Internal electronics failure.
Internal electronics failure.
The transmitter has lost communi-
cation with the core processor.
There may be a problem with the
wiring or with either component.
Internal electronics failure.
This can indicate a loss of communi-

Recommended actions
• Verify all of the characterization or cali-
bration parameters. See the sensor tag
or the calibration sheet for your meter.
• Ensure that the correct board is instal-
led.
• Verify the setting of the Sensor Type pa-
rameter.
• If Sensor Type=Curved Tube, ensure that
no parameters specific to Straight Tube
have been set.
• Cycle power to the meter.
• Contact customer support.
• Cycle power to the meter.
• Contact customer support.
• Cycle power to the meter.
• Contact customer support.
• Check the wiring between the sensor
and the transmitter.
• Check for noise in the wiring or in the
transmitter environment.
• Verify that internal wiring is secure and
that there are no internal electrical
problems.
• Check the status LED on the core pro-
cessor.
• Check the resistance across core pro-
cessor terminals.
• If the alert persists:
- Replace the core processor.
- If that does not solve the problem,
restore the original core processor
and replace the transmitter.
- If that does not solve the problem,
replace both the transmitter and
the core processor.
