5.6.2 Performing digital-to-analog trim (4-20mA/ 1-5 V 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, 2 to 10 volts if measuring across a 500 
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.
Performing a 4-20/ 1-5 V mA output trim using other scale with
