Basic setup

2.7.1 Set process variable units
Fast Keys
The PV Unit command sets the process variable units to allow you to monitor your process
using the appropriate units of measure.
Field Communicator
Enter the Fast Key sequence shown. Select from the following engineering units:
inH

AMS Device Manger
Right click on the device and select Configuration Properties from the menu. In the Basic
Setup tab, use Unit drop down menu to select units.
2.7.2 Rerange
The Range Values command sets the 4 and 20 mA points and digital lower (LRV) and upper
(URV) range values. In practice, you may reset the transmitter range values as often as
necessary to reflect changing process conditions. Changing the lower or upper range point
results in similar changes to the span.
Note
Transmitters are shipped from Emerson Process Management. fully calibrated per request
or by the factory default of full scale (span = upper range limit.)
Use one of the methods below to rerange the transmitter. Each method is unique; examine
all options closely before deciding which method works best for your process.
