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
programmed 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. Max: Maximum analog output value allowed regardless of input
5. Min: Minimum analog output value allowed regardless of input
6. 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, 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
milliamp 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.
