Milliamp output problems and recommended actions (continued)Table 10-6:
Problem Possible causes Recommended actions
mA output consis-
tently out of range
• Incorrect process variable or units assigned
to output
• Fault condition if fault action is set to up-
scale or downscale
• LRV and URV are not set correctly
• Verify the output variable assignments.
• Verify the measurement units configured
for the output.
• Check the Fault Action settings. See
Section 10.19.
• Check the settings of Upper Range Value and
Lower Range Value. See Section 10.18.
• Check the mA output trim. See
Section 10.17.
Consistently incorrect
mA measurement
• Loop problem
• Output not trimmed correctly
• Incorrect flow measurement unit config-
ured
• Incorrect process variable configured
• LRV and URV are not set correctly
• Check the mA output trim. See
Section 10.17.
• Verify that the measurement units are con-
figured correctly for your application.
• Verify the process variable assigned to the
mA output.
• Check the settings of Upper Range Value and
Lower Range Value. See Section 10.18.
mA output correct at
lower current, but in-
correct at higher cur-
rent
• mA loop resistance may be set too high • Verify that the mA output load resistance
is below maximum supported load (see
the installation manual for your transmit-
ter).
