Note the following:
• During the trim, the transmitter’s mA output will not report process data.
CAUTION! Do not
use the mA output for process control while you are performing the trim.
• Enter the measured value in the same scale that you specified for the mA measurement point.
If you specified “Don’t Know”:
- If you are using ProLink II, enter the measured value in one scale and the tool will display
the equivalent value in the other scale.
- If you are using the Communicator, you must specify the mA measurement point before
you can continue.
• Any trimming performed on the output should not exceed ± 200 microamps. If more trimming
is required, contact Micro Motion customer support.
• If you are using the Communicator, the receiving device value can contain up to two decimal
places.
