Parameters
2.6. Analog Output Scaling
2.6.1. Current Output Function
Can be set to either Level, Space, or Distance.
To view the mA reading in the secondary region of the LCD, press on the
handheld programmer.
To modify Current Output Function via SIMATIC PDM:
• Open the menu Device – Select Analog Output.
Notes:
• Level, space, and distance have different reference points.
• Use caution when changing Current Output Function while the device is
connected to a HART network. Current Output Function controls the
primary value. Changes to Current Output Function will update the mA
Setpoints.
• Current Output Function also affects the secondary, tertiary and
quaternary variables in a HART network.

difference between High Calibration
Point and Low Calibration Point
