Scaling the 4-20 mA Analog Output (
Aout
)
The 4-20 mA analog output can be scaled to provide a 4-20 mA signal for any display range selected.
No equipment is needed to scale the analog output; simply program the display values to the
corresponding mA output signal.
The
Analog Output
menu is used to program the 4-20 mA output based on display values.
Note: During the analog output scaling, the display value is always indicated with a decimal point
regardless of the decimal point selection for the temperature display.
For instructions on how to program numeric
values see
Setting Numeric Values
, page 27.
Reset Menu (
reset
)
The
Reset
menu is used to reset the maximum or minimum reading (peak or valley) reached by the
process; both may be reset at the same time by selecting “reset high & low” (
rst HL
).
Control Menu (
Contrl
)
The
Control
menu is used to control the 4-20 mA analog output and the relays manually, ignoring the
input. Each relay and analog output can be programmed independently for manual control. Selecting
automatic control sets all relays and analog output for automatic operation.
