Milliamp output problems and recommended actions (continued)Table 14-7:
Problem Possible causes Recommended actions
Consistently incorrect
mA measurement
• Loop problem
• Output not trimmed correctly
• Incorrect measurement unit configured for
process variable
• Incorrect process variable configured
• LRV and URV are not set correctly
• Check the mA output trim. See
Section 14.15.
• 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 14.17.
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 the maximum supported load
(see the installation manual for your trans-
mitter).
