5.4.2 Milliamp output trim with a Communicator
See Figure 5-6 for the mA output trim procedure.
Note the following:
If you are trimming the primary mA output, the HART/Bell202 signal to the
Communicator will affect the reading. Disconnect the Communicator before
reading the output, then reconnect and resume the trim, after taking the
reading.
Any trimming performed on the output should not exceed ± 200 microamps.
If more trimming is required, contact Micro Motion customer support.
The receiving device value that you enter in the Communicator can contain
up to two decimal places.
