4: Terminal A3 only
5: Terminals A1 and A3
6: Terminals A2 and A3
7: All terminals enabled
Default: 7
Range: 1 to 7

Terminal A3 Offset
TerminalA3Offset
Adds an offset when the analog signal to terminal A3 is at 0 V.
Default: 0
Min.: -500
Max.: 500
<1> Default is 0 when b5-01 is set to 0.
Default is B when b5-01 is set to 1 or 3.
