5.8.2 Performing digital-to-analog trim (4–20 mA/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 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.
Performing a 4–20/1–5 V mA output trim using other scale
