Checking the test points

Some status alarms that indicate a sensor failure or overrange condition can be caused by problems 
other than a failed sensor. You can diagnose sensor failure or overrange status alarms by checking the 
meter test points. The 

test points

 include left and right pickoff voltages, drive gain, and tube 

frequency. These values describe the current operation of the sensor.

To read the current test point values, use the procedure described in Section 15.11.

15.16.1

Evaluating the test points

Use the following guidelines to evaluate the test points:

•

If the drive gain is erratic, negative, or saturated, refer to Section 15.16.2.

•

If the value for the left or right pickoff does not equal the appropriate value from Table 15-4, 
based on the sensor flow tube frequency, refer to Section 15.16.3

.

•

If the values for the left and right pickoffs equal the appropriate values from Table 15-4, based 
on the sensor flow tube frequency, record your troubleshooting data and contact the Micro 
Motion customer service department for assistance. See Section 1.8.

15.16.2

Drive gain problems

Problems with drive gain can appear in several different forms:

•

Erratic drive gain (e.g., rapid shifting from positive to negative)

•

Negative drive gain

•

Saturated or excessive (near 100%) drive gain 

See Table 15-5 for a list of possible problems and remedies.

Drive gain problems, causes, and remedies

Cause

Possible remedy

Excessive slug flow

See Section 15.12.

Plugged flow tube

Purge the flow tubes.

Cavitation or flashing

Increase inlet or back pressure at the sensor.

If a pump is located upstream from the sensor, increase the distance 
between the pump and sensor.
