4.5 Changing the measurement units
The transmitter is able to store measurement units in two different places: in the transducer block and
in the AI blocks. These two units locations are independent and can be set to different values. This
affects configuration in the following ways:
• If you are using a PROFIBUS configuration tool or the display, units will be set to match in
both the relevant AI block and the transducer block.
• If you are using ProLink II, use the
Function Block tab to configure units. Although units can
be configured on some of the other tabs, doing so may produce unintended results.
Note: Changing the measurement units for a process variable automatically changes the associated
totalizer units as well. For example, setting the mass flow units to g/s will automatically set the mass
totalizer unit to grams.
Note: Configure the AI block channel before configuring the AI block units. The AI blocks will
produce an error if the measurement units are set to a value that is impossible for the configured
channel.
To configure measurement units, refer to Tables 4-2 through 4-7 and the flowcharts in Figures 2-1
and 2-3.
