5.6.2 Performing digital-to-analog trim (4-20 mA output trim)
using other scale
The scaled 4-20 mA output trim command matches the 4 and 20 mA points to a user
selectable reference scale other than 4 and 20 mA (for example, two to ten volts if
measuring across a 500 Ω load or 0 to 100 percent if measuring from a Distributed Control
System (DCS)).
To perform a scaled 4-20 mA output trim, connect an accurate reference meter to the
transmitter and trim the output signal to scale as outlined in the output trim procedure.
