Analog Output Programming (AoutPr)
The Analog Output Programming menu is used to program the behavior
of the 4-20 mA output. The following parameters and functions are pro-
grammed in this menu:
1. Source: Source for generating the 4-20 mA output (e.g. PV)
2. Overrange: Analog output value with display in overrange condition
3. Underrange: Analog output value with display in underrange condition
4. Break: Analog output value when loop break is detected
5. Max: Maximum analog output value allowed regardless of input
6. Min: Minimum analog output value allowed regardless of input
7. Calibrate: Calibrate the internal 4-20 mA source reference used to
scale the 4-20 mA output
Analog Output Source
The source for generating the 4-20 mA output may be assigned to the
rate/process variable, total, grand total, maximum or minimum value
reached by the rate/process, or one of the set points, or the Modbus PV
input.

Analog Output Calibration
To perform the analog output calibration it’s recommended to use a mil-
liamp meter with a resolution of at least 0.1 µA to measure the output
current. The values saved internally during this procedure are used for
scaling the 4-20 mA output in the Setup menu.
