Possible causes
The loaded software is not
compatible with the pro-
grammed board type.
The signal from the sensor
pickoff(s) is insufficient. This
suggests that the sensor
tubes or vibrating elements
are not vibrating. This alert
often occurs in conjunction
with Alert 102.
The measured viscosity is
above the highest range for
which the device is calibra-
ted.
Known Density Verification
failed.
The time period signal is
outside the limits for the
sensor type.
The calculated mA output
value is outside the config-
ured range.
The HART address is set to a
non-zero value, or the mA
output is configured to send
a constant value.

Recommended actions
• Contact Micro Motion.
• Check for foreign material in the process gas or
fluid, coating, or other process problems.
• Check for fluid separation by monitoring the den-
sity value and comparing the results against ex-
pected density values.
• Ensure that the sensor orientation is appropriate
for your application. Settling from a two-phase or
three-phase fluid can cause this alert.
• Check your process against the values reported by
the device.
• Contact Micro Motion.
• Check the subtest results and perform the recom-
mended actions.
• Retry the test.
• Contact Micro Motion.
• Check your process conditions against the values
reported by the device.
• Check the settings of Upper Range Value and Lower
Range Value. See Section
• Check process conditions. Actual conditions may
be outside the normal conditions for which the
output is configured.
• Check for foreign material in the process gas or
fluid, coating, or other process problems.
• Verify that the measurement units are configured
correctly for your application.
• Check whether the output is in loop test mode. If
it is, unfix the output.
• Exit mA output trim, if applicable.
• Check the HART address. If the HART address is
non-zero, you may need to change the setting of
mA Output Action (Loop Current Mode).
• Check whether the output has been set to a con-
stant value via digital communication.
