the Product into the dialog box.
3. Push Send to trim the low analog output point.
4. To trim the high analog output point, do steps 2 and
3 again. Follow the prompts on the display.
Sensor Trim
You can only do a Sensor Trim on a supported
transmitter. A Sensor Trim adjusts the Input block of a
HART transmitter. If your application does not use the
Output block of the transmitter, Sensor Trim is the only
adjustment necessary.
A Sensor Trim can involve one or more trim points. This
is controlled by the transmitter’s software.
To do a Sensor Trim:
1. From the Active Device screen, push the Service
softkey, and then Sensor Trim. See Figure 16.
