3. From the Maintenance menu, select Calibration (see Figure 16-1).
4. Select
mA Output Trim.
5. Select
Milliamp Output 1 or Milliamp Output 2.
6. Select the output level to be trimmed:
• To trim at 4 mA, select
Trim 4.0 mA
• To trim at 20 mA, select Trim 20.0 mA
7. Press CHG, enter the amount of current indicated by the reference device, then press SAVE.
8. Compare the output level that is indicated by the reference device to the output level that
appears in the display.
• If the output level that appears in the display matches the output level that is indicated by
the reference device, press
YES.
• If the output level that appears in the display does
not match the output level that is
indicated by the reference device, press
NO, then repeat Steps 7 and 8.
Note: Any trimming performed on the output should not exceed ± 200 microamps. If more trimming is
required, contact Micro Motion customer support.
Note: If you are trimming the primary mA output, and you are performing a trim using a HART
connection to the Series 3000 device, the HART signal will affect the reading. Disconnect the HART
connection before reading the output, then reconnect and resume the trim after taking the reading.
